- Add type for
hasNext
to the query and mutation results Submitted by @JoviDeCroock (See #3703)
- Support use of defer with suspense Submitted by @AndrewIngram (See #3687)
- Mark
@urql/core
as a peer dependency as well as a regular dependency Submitted by @kitten (See #3579)
- Updated dependencies (See #3520, #3553, and #3520)
- @urql/[email protected]
- Prioritise
context.suspense
and fallback to checkingclient.suspense
Submitted by @JoviDeCroock (See #3427) - Updated dependencies (See #3430)
- @urql/[email protected]
⚠️ Fix edge case that causes execute functions fromuseQuery
anduseSubscription
to fail when they’re called in their state after a render that changespause
. This would previously cause internal dependencies to be outdated and the source to be discarded immediately in some cases Submitted by @kitten (See #3323)- Updated dependencies (See #3317 and #3308)
- @urql/[email protected]
- Switch
react
imports to namespace imports, and update build process for CommonJS outputs to interoperate with__esModule
marked modules again Submitted by @kitten (See #3251)
- Avoid unnecessary re-render when two components use the same query but receive unchanging results, due to differing operations Submitted by @nathan-knight (See #3195)
- Remove the default
Client
fromContext
. Previously,urql
kept a legacy default client in its context, with default exchanges and calling an API at/graphql
. This has now been removed and you will have to create your ownClient
if you were relying on this behaviour Submitted by @JoviDeCroock (See #3033)
- Allow mutations to update their results in bindings when
hasNext: true
is set, which indicates deferred or streamed results Submitted by @kitten (See #3103)
⚠️ Fix source maps included with recently published packages, which lost theirsourcesContent
, including additional source files, and had incorrect paths in some of them Submitted by @kitten (See #3053)- Upgrade to
wonka@^6.3.0
Submitted by @kitten (See #3104) - Silence "Cannot update a component (%s) while rendering a different component (%s)." warning forcefully Submitted by @kitten (See #3095)
- Add TSDocs to all
urql
bindings packages Submitted by @kitten (See #3079) - Updated dependencies (See #3101, #3033, #3054, #3053, #3060, #3081, #3039, #3104, #3082, #3097, #3061, #3055, #3085, #3079, #3087, #3059, #3055, #3057, #3050, #3062, #3051, #3043, #3063, #3054, #3102, #3097, #3106, #3058, and #3062)
- @urql/[email protected]
⚠️ Fix type utilities turning thevariables
properties optional when a type fromTypedDocumentNode
has noVariables
or all optionalVariables
. Previously this would break for wrappers, e.g. in code generators, or when the type didn't quite match what we'd expect Submitted by @kitten (See #3022)- Updated dependencies (See #3007, #2962, #3007, #3015, and #3022)
- @urql/[email protected]
⚠️ Fixfetching
going tofalse
after changing variables in a subscription, by @JoviDeCroock (See #2667)
- Update generics for components, by @JoviDeCroock (See #2663)
- Updated dependencies (See #2665)
- @urql/[email protected]
- Tweak the variables type for when generics only contain nullable keys, by @JoviDeCroock (See #2623)
- Goodbye IE11! 👋 This major release removes support for IE11. All code that is shipped will be transpiled much less and will not be ES5-compatible anymore, by @kitten (See #2504)
- Implement stricter variables types, which require variables to always be passed and match TypeScript types when the generic is set or inferred. This is a breaking change for TypeScript users potentially, unless all types are adhered to, by @kitten (See #2607)
- Upgrade to Wonka v6 (
wonka@^6.0.0
), which has no breaking changes but is built to target ES2015 and comes with other minor improvements. The library has fully been migrated to TypeScript which will hopefully help with making contributions easier!, by @kitten (See #2504)
⚠️ Fix missing React updates after an incoming response that schedules a mount. We now prevent dispatched operations from continuing to flush synchronously when the original source that runs the queue has terminated. This is important for the React bindings, because an update (e.g.setState
) may recursively schedule a mount, which then disabled othersetState
updates from being processed. Previously we assumed that React used a trampoline scheduler for updates, however it appears thatsetState
can recursively start more React work, by @kitten (See #2556)- Updated dependencies (See #2556)
- @urql/[email protected]
⚠️ Fix Node.js ESM re-export detection for@urql/core
inurql
package and CommonJS output for all other CommonJS-first packages. This ensures that Node.js'cjs-module-lexer
can correctly identify re-exports and report them properly. Otherwise, this will lead to a runtime error, by @kitten (See #2485)
⚠️ Fix issue where a paused subscription would execute with stale variables, by @JoviDeCroock (See #2463)
- Revert to the previous
useQuery
implementation,use-sync-external-store
seems to be causing some unexpected timing issues, by @JoviDeCroock (See #2308)
- Updated dependencies (See #2295)
- @urql/[email protected]
⚠️ fix diff data correctly for the next state computing, this avoids having UI-flashes due to undefined data, by @JoviDeCroock (See #2238)⚠️ fix issue where the cache infinitely loops, by @JoviDeCroock (See #2237)
- Update
useQuery
implementation to avoid an aborted render on initial mount. We abort a render-on-update once when the state needs to be updated according to theOperationResult
source we need to listen to and execute. However, we can avoid this on the initial mount as we've done in a prior version. This fix does not change any of the current behaviour, but simply avoids the confusing state transition on mount, by @kitten (See #2227) - Updated dependencies (See #2228)
- @urql/[email protected]
- pin version for
use-sync-external-store
, by @JoviDeCroock (See #2223)
- Leverage the new
use-sync-external-store
package anduseSyncExternalStore
hook inuseQuery
implementation to bring the state synchronisation in React in line with React v18. While the current implementation works already with React Suspense and React Concurrent this will reduce the maintenance burden of our implementation and ensure certain guarantees so that React doesn't break us, by @JoviDeCroock (See #2164)
⚠️ FixuseMutation
not working correctly with React 18, by @Dremora (See #2158)- Updated dependencies (See #2189, #2153, #2210, and #2198)
- @urql/[email protected]
- Extend peer dependency range of
graphql
to include^16.0.0
. As always when upgrading across many packages ofurql
, especially including@urql/core
we recommend you to deduplicate dependencies after upgrading, usingnpm dedupe
ornpx yarn-deduplicate
, by @kitten (See #2133) - Updated dependencies (See #2133)
- @urql/[email protected]
⚠️ Fix issue where a paused query would not behave correctly when callingexecuteQuery
, this scenario occured when the query has variables, there would be cases where on the first call it would think that the dependencies had changed (previous request vs current request) which made the source reset to null, by @JoviDeCroock (See #1982)- Updated dependencies (See #1944)
- @urql/[email protected]
⚠️ Fix issue withuseQuery
'sexecuteQuery
state updates, where some calls wouldn't trigger a source change and start a request when the hook was paused, by @kitten (See #1722)- Updated dependencies (See #1709)
- @urql/[email protected]
- Remove closure-compiler from the build step (See #1570)
- Updated dependencies (See #1570, #1509, #1600, and #1515)
- @urql/[email protected]
- Add a displayName to the Provider, by @JoviDeCroock (See #1431)
⚠️ Fix issue whereuseSubscription
would endlessly loop when the callback wasn't memoized, by @JoviDeCroock (See #1384)⚠️ Fix case where identicaluseQuery
calls would result in cross-component updates, by @JoviDeCroock (See #1383)
- Breaking: Remove
pollInterval
option fromuseQuery
. Instead please consider usinguseEffect
callingexecuteQuery
on an interval, by @kitten (See #1374)
- Reimplement
useQuery
to apply a consistent Suspense cache (torn down queries will still eliminate stale values) and support all Concurrent Mode edge cases. This work is based onuseMutableSource
's mechanisms and allows React to properly fork lanes since no implicit state exists outside ofuseState
in the implementation. TheuseSubscription
hook has been updated similarly without a cache or retrieving values on mount, by @kitten (See #1335) - Remove deprecated
operationName
property fromOperation
s. The newOperation.kind
property is now preferred. If you're creating new operations you may also use themakeOperation
utility instead. When upgrading@urql/core
please ensure that your package manager didn't install any duplicates of it. You may deduplicate it manually usingnpx yarn-deduplicate
(for Yarn) ornpm dedupe
(for npm), by @kitten (See #1357)
- Updated dependencies (See #1374, #1357, and #1375)
- @urql/[email protected]
⚠️ Fix edge cases related to Suspense triggering on an update in Concurrent Mode. Previously it was possible for stale state to be preserved across the Suspense update instead of the new state showing up. This has been fixed by preventing the suspending query source from closing prematurely, by @kitten (See #1308)
⚠️ Fix Suspense when results share data, this would return partial results for graphCache and not update to the eventual data, by @JoviDeCroock (See #1282)
- Add a built-in
gql
tag function helper to@urql/core
. This behaves similarly tographql-tag
but only warns about locally duplicated fragment names rather than globally. It also primes@urql/core
's key cache with the parsedDocumentNode
, by @kitten (See #1187) - Add
suspense: false
to options whenexecuteQuery
is called explicitly, by @kitten (See #1181) - Updated dependencies (See #1187, #1186, and #1186)
- @urql/[email protected]
⚠️ Fix in edge-case in client-side React Suspense, where after suspending due to an update a new state value is given touseSource
in a render update. This was previously then causing us to subscribe to an outdated source inuseEffect
since the updated source would be ignored by the time we reachuseEffect
inuseSource
, by @kitten (See #1157)
⚠️ Fix regression in client-side Suspense behaviour. This has been fixed in[email protected]
and@urql/[email protected]
but regressed in the patches afterwards that were aimed at fixing server-side Suspense, by @kitten (See #1142)
⚠️ Fix server-side rendering by disabling the new Suspense cache on the server-side and clear it for prepasses, by @JoviDeCroock (See #1138)- Updated dependencies (See #1135)
- @urql/[email protected]
- Improve the Suspense implementation, which fixes edge-cases when Suspense is used with subscriptions, partially disabled, or used on the client-side. It has now been ensured that client-side suspense functions without the deprecated
suspenseExchange
and uncached results are loaded consistently. As part of this work, theClient
itself does now never throw Suspense promises anymore, which is functionality that either way has no place outside of the React/Preact bindings, by @kitten (See #1123)
- Add support for
TypedDocumentNode
to infer the type of theOperationResult
andOperation
for all methods, functions, and hooks that either directly or indirectly accept aDocumentNode
. Seegraphql-typed-document-node
and the corresponding blog post for more information., by @kitten (See #1113) - Refactor
useSource
hooks which powersuseQuery
anduseSubscription
to improve various edge case behaviour. This will not change the behaviour of these hooks dramatically but avoid unnecessary state updates when any updates are obviously equivalent and the hook will furthermore improve continuation from mount to effects, which will fix cases where the state between the mounting and effect phase may slightly change, by @kitten (See #1104) - Updated dependencies (See #1119, #1113, #1104, and #1123)
- @urql/[email protected]
⚠️ Fix the production build overwriting the development build. Specifically in the previous release we mistakenly replaced all development bundles with production bundles. This doesn't have any direct influence on how these packages work, but prevented development warnings from being logged or full errors from being thrown, by @kitten (See #1097)- Updated dependencies (See #1097)
- @urql/[email protected]
- Deprecate the
Operation.operationName
property in favor ofOperation.kind
. This name was previously confusing asoperationName
was effectively referring to two different things. You can safely upgrade to this new version, however to mute all deprecation warnings you will have to upgrade allurql
packages you use. If you have custom exchanges that spread operations, please use the newmakeOperation
helper function instead, by @bkonkle (See #1045) - Updated dependencies (See #1094 and #1045)
- @urql/[email protected]
⚠️ Fix React Fast Refresh beng broken due to an invalid effect, by @JoviDeCroock (See #969)
- Add the operation to the query, mutation and subscription result, by @JoviDeCroock (See #924)
- Update hooks to be exported functions rather than exported block-scoped variables to provide TypeScript consumers with better access to their signature, by @dotansimha (See #904)
- Updated dependencies (See #911 and #908)
- @urql/[email protected]
- Upgrade to a minimum version of wonka@^4.0.14 to work around issues with React Native's minification builds, which use uglify-es and could lead to broken bundles, by @kitten (See #842)
- Updated dependencies (See #838 and #842)
- @urql/[email protected]
- Bump @urql/core to ensure exchanges have dispatchDebug, this could formerly result in a crash, by @JoviDeCroock (See #726)
- Add graphql@^15.0.0 to peer dependency range, by @kitten (See #688)
- Forcefully bump @urql/core package in all bindings and in @urql/exchange-graphcache.
We're aware that in some cases users may not have upgraded to @urql/core, even though that's within
the typical patch range. Since the latest @urql/core version contains a patch that is required for
cache-and-network
to work, we're pushing another patch that now forcefully bumps everyone to the new version that includes this fix, by @kitten (See #684) - Updated dependencies (See #688 and #678)
- @urql/[email protected]
- Avoid setting state on an unmounted component when useMutation is used, by @JoviDeCroock (See #656)
- Updated dependencies (See #658 and #650)
- @urql/[email protected]
⚠️ Fix bundling for packages depending on React, as it doesn't have native ESM bundles, by @kitten (See #646)
⚠️ Fix node resolution when using Webpack, which experiences a bug where it only resolvespackage.json:main
instead ofmodule
when an.mjs
file imports a package, by @JoviDeCroock (See #642)- Updated dependencies (See #642)
- @urql/[email protected]
⚠️ Fix Node.js Module support for v13 (experimental-modules) and v14. If your bundler doesn't support.mjs
files and fails to resolve the new version, please double check your configuration for Webpack, or similar tools, by @JoviDeCroock (See #637)- Updated dependencies (See #637)
- @urql/[email protected]
- Bumps the
@urql/core
dependency minor version to ^1.10.1 for React, Preact and Svelte, by @JoviDeCroock (See #623) - Avoid React v16.13.0's "Warning: Cannot update a component" by preventing cross-hook updates during render or initial mount, by @kitten (See #630)
- Updated dependencies (See #621)
- @urql/[email protected]
⚠️ Fix more concurrent-mode and strict-mode edge cases and bugs by switching to useSubscription. (See #514)⚠️ Fix client-side suspense support (as minimally as possible) by altering the useBehaviourSubject behaviour. (See #512)- Updated dependencies (See #533, #519, #515, #512, and #518)
- @urql/[email protected]
This patch fixes client-side suspense. While we wouldn't recommend its use
anymore, since suspense lends itself to prerendering instead of a loading
primitive, we'd like to ensure that suspense-mode works as expected in urql
.
Also, as mentioned in v1.8.0
's notes, please ensure that urql
upgrades to
use wonka@^4.0.7
to avoid any issues. If your bundler or packager uses a
lower version with urql
, you will see runtime errors.
- Clean up unnecessary
useMemo
foruseCallback
in hooks (see #504) - Fix synchronous, client-side suspense and simplify
toSuspenseSource
helper (see #506)
This patch fixes urql
relying on a quirk in older versions of wonka
where
shared sources wouldn't cascade cancellations, which they now do. This meant
that when an app goes from some queries/subscriptions to having none at all,
the exchange pipeline would be stopped completely.
- Fix exchange pipeline stalling when all queries end (see #503)
This release doesn't change any major feature aspects, but comes with bugfixes
to our suspense and concurrent-mode handling. Due to an upgrade to wonka@^4.0.0
this is a minor version though.
In v1.6.0 we believed to
have solved all issues related to suspense and concurrent mode. However there were
still some remaining cases where concurrent mode behaved incorrectly. With the new
useOperator
hook in [email protected]
we believe
to have now fixed all issues.
The initial mount of useQuery
and useSubscription
will now synchronously reflect
whatever urql
returns, most of the times those will be cached results. Afterwards
all subsequent updates and fetches will be scheduled cooperatively with React on
an effect.
If you're using wonka
for an exchange with urql
you may want to upgrade to wonka@^4.0.5
soon.
You can still use the older v3.2.2
which will work with the new version (even in the same bundle),
unless you're making use of its subscribe
, make
, or makeSubject
exports.
A migration guide can be found in the wonka
docs.
- Support concurrent mode with all edge cases fully (see #496)
- Move to
[email protected]
with the prior fix in #496 (see #499)
This release splits our main package into two entrypoints. Importing from urql
remains
unchanged, but internally this entrypoint uses urql/core
, which doesn't contain any
React-related code. If you're building framework-agnostic libraries or apps without
React, you can now use urql/core
directly.
- Fix
originalError
onGraphQLError
instances (see #470) - Fix
stringifyVariables
not using.toJSON()
which prevented Dates from being stringified, by @BjoernRave (see #485) - Expose
urql/core
without any React code included (see #424)
- Fix suspense-mode being erroneously activated when using
client.query()
(see #466)
This fixes a potentially critical bug, where a component would enter an infinite rerender loop,
when another hook triggers an update. This may happen when multiple useQuery
hooks are used in
a single component or when another state hook triggers a synchronous update.
- Add generic type-parameter to
client.query
andclient.mutation
, by @ctrlplusb (see #456) ⚠️ FixuseQuery
entering an infinite loop during SSR when an update is triggered (see #459)
- Fix hook updates not being propagated to potential context providers (see #451)
This release comes with stability improvements for the useQuery
and useSubscription
hooks
when using suspense and concurrent mode. They should behave the same as before under normal
circumstances and continue to deliver the correct state on initial mount and updates.
The useQuery
hook may however now trigger suspense updates when its inputs are changing,
as it should, instead of erroneously throwing a promise in useEffect
.
The added stale: boolean
flag on the hooks indicates whether a result is "stale".
useQuery
will expose stale: true
on results that are cached but will be updated
due to the use of cache-and-network
.
We've also made some changes so that client.query()
won't throw a promise, when suspense
mode is activated.
- ✨ Add
stale
flag toOperationResult
and hook results (see #449) - Replace
useImmeditateEffect
anduseImmediateState
withreact-wonka
derived state and effect (see #447) - Add (internal)
suspense
flag toOperationContext
- Replace
fast-json-stable-stringify
with embedded code (see #426) - ⚠ Prevent caching
null
data (see #437)
This release finally adds shortcuts to imperatively make queries and mutations. They make it easier to quickly use the client programmatically, either with a Wonka source-based or Promise-based call.
// Call .query or .mutation which return Source<OperationResult>
const source = client.query(doc, vars);
const source = client.mutation(doc, vars);
// Call .toPromise() on the source to get Promise<OperationResult>
const promise = client.query(doc, vars).toPromise();
const promise = client.mutation(doc, vars).toPromise();
This version also adds a useClient
hook as a shortcut for useContext(Context)
.
We provide a default client that makes requests to /graphql
. Since that has
confused users before, we now log a warning, when it's used.
- ✨ Implement
client.query()
andclient.mutation()
(see #405) - Fix
useImmediateEffect
for concurrent mode (see #418) - Deconstruct
Wonka.pipe
using a Babel transform (see #419) - ⚠ Add
useClient
hook and warning when default client is used (see #420)
This release adds "active teardowns" for operations, which means that an exchange can now send a teardown to cancel ongoing operations. The subscriptionsExchange
for instance now ends ongoing subscriptions proactively if the server says that they've completed! This is also reflected as fetching: false
in the useQuery
and useSubscription
hook.
We've also fixed a small issue with suspense and added all features from useQuery
to useSubscription
! This includes the pause
argument and an executeSubscription
function.
- ✨ Implement active teardowns and add missing features to
useSubscription
(see #410) - Fix
UseMutationResponse
TypeScript type, by @jbugman (see #412) - Exclude subscriptions from suspense source (see #415)
This release removes all metadata for the @urql/devtools
extension from the core
urql
package. This data will now be generated internally in the devtools exchange
itself. Please also upgrade to the latest @urql/devtools
version if you're using
the extension.
This release has mainly been focused on minor refactors to keep the bundlesize low.
But it also introduces new features, like specifying a default requestPolicy
and
a new polling option on useQuery
!
This release also exports makeResult
and makeErrorResult
, which will reduce the
boilerplate code that you need for custom fetch exchanges.
- Minor bundlesize optimizations and remove
debugExchange
in production (see #375) - ✨ Add
requestPolicy
option toClient
to change the default request policy (see #376) - ⚠ Remove dependency on
graphql-tag
and improveOperation.key
hashing (see #383) - Remove
networkLatency
andsource
metadata from context, and deleteuseDevtoolsContext
(see #387 and #388) - ✨ Add support for polling with
pollInterval
argument touseQuery
, by @mxstbr (see #397) - ⚠ Prevent
__typename
from being added to the toplevel GraphQL documents (see #399) - Add
operationName
field tofetch
request body (see #401)
This release comes with some important fixes and enhancements, which all address
certain edge-cases when using urql
.
It fixes the cache-and-network
request policy, which wouldn't always work correctly and issue another network request after resolving a response from the default cache. We also had a major bug in React Native environments where responses wouldn't ever be reflected in the useQuery
hook's state. Lastly, you can now use extensions
from your GraphQL servers and modify the OperationContext
from the hooks options.
- ✨ Add support for
extensions
key in GraphQL responses, by @adamscybot (see #355) - ⚠ Fix
cache-and-network
request policy by adding operation flushing to the client (see #356) - Add
fetch
option to the Client so it doesn't have to be polyfilled globally (see #357 and #359) - ⚠ Fix
useImmediateState
for React Native environments (see #358) - ✨ Add
context
option to all hooks to allowOperationContext
to be changed dynamically (see #351) - Add
isClient
option tossrExchange
in casesuspense
is activated on the client-side (see #369)
A release focused on improving developer experience (in preparation for the upcoming devtools) as well as minor documentation improvements and bug fixes.
- Add metadata to operation context in development (see #305, #324, #325 and #329)
- Fix minor typename memory leak (see #321)
- Fix types for react subscription components (see #328)
- Fix displayName attributes not populated in examples (see #330)
- Fix error in
collectTypes
method (see #343) - Fix HTTP status bounds check error (see #348)
This is a hotfix that patches a small regression from 1.1.2
where
useQuery
would crash due to an incorrect teardown function from pause.
- Fix
executeQuery
dispose function whenpause
is set, by@JoviDeCroock (see #315)
This patch fixes a small bug that usually manifests in development,
where the initial state would be incorrect after a fast response from
the GraphQL API. This used to lock the state into fetching: true
indefinitely in some cases.
- Export all TS types for components (see #312)
⚠️ Fix state getting stuck on initial mount for fast responses (see #310)- Refactor build tooling to be driven only by Rollup (see #306)
- Remove dev-only dependencies from
dependencies
(see #304)
This release comes with two small patches. One being a critical fix, where cancelled requests would be erroneously deduped, which meant a previously cancelled query would never be fetched.
It also refactors our bundling process to transpile Object.assign
to
restore IE11 support and reduce the amount of duplicate helper in our bundles.
⚠️ Fix torn-down requests being deduped forever (see #281)- Fix
useQuery
'spause
argument blocking explicitexecuteQuery
calls (see #278) - Add
Object.assign
transpilation for IE11 and refactor bundling (see #274)
This release introduces support for server-side rendering. You can find out more about it by reading the new Basics section on how to set it up.
This version now also requires a version of React supporting hooks! (>= 16.8.0)
We unfortunately forgot to correct the peerDependencies
entries in our v1.0.0 release.
- ✨ Add server-side rendering support (see #268)
- ✨ Ensure that state changes are applied immediately on mount (see #256)
- Ensure that effects are run immediately on mount (see #250)
⚠️ Removecreate-react-context
and bump React peer dependency (see #252)- Add generics to the

Since the entire library has been rewritten for v1.0.0, no changes are listed here!
urql
v1 is more customisable than ever with "Exchanges", which
allow you to change every aspect of how urql
works.
