This is the fourth blog in a multipart series where we will be building Chatty, a WhatsApp clone, using React Native and Apollo.
Here’s what we will accomplish in this tutorial:
- Design GraphQL Mutations and add them to the GraphQL Schemas on our server
- Modify the layout on our React Native client to let users send Messages
- Build GraphQL Mutations on our RN client and connect them to components using
react-apollo - Add Optimistic UI to our GraphQL Mutations so our RN client updates as soon as the Message is sent — even before the server sends a response!
YOUR CHALLENGE
- Add GraphQL Mutations on our server for creating, modifying, and deleting Groups
- Add new Screens to our React Native app for creating, modifying, and deleting Groups
- Build GraphQL Queries and Mutations for our new Screens and connect them using
react-apollo
While GraphQL Queries let us fetch data from our server, GraphQL Mutations allow us to modify our server held data.
To add a mutation to our GraphQL endpoint, we start by defining the mutation in our GraphQL Schema much like we did with queries. We’ll define a createMessage mutation that will enable users to send a new message to a Group:
type Mutation {
# create a new message
# text is the message text
# userId is the id of the user sending the message
# groupId is the id of the group receiving the message
createMessage(text: String!, userId: Int!, groupId: Int!): Message
}
GraphQL Mutations are written nearly identically like GraphQL Queries. For now, we will require a userId parameter to identify who is creating the Message, but we won’t need this field once we implement authentication in a future tutorial.
Let’s update our Schema in server/data/schema.js to include the mutation:

We can easily test our newly minted createMessage mutation in GraphIQL to make sure everything works:
Wow, that was way faster than when we added queries! All the heavy lifting we did in the first 3 parts of this series is starting to pay off….
Now that our server allows clients to create messages, we can build that functionality into our React Native client. First, we’ll start by creating a new component MessageInput where our users will be able to input their messages.
For this component, let's use cool icons. react-native-vector-icons is the goto package for adding icons to React Native. Please follow the instructions in the react-native-vector-icons README before moving onto the next step.
# make sure you're adding this package in the client folder!!!
cd client
yarn add react-native-vector-icons

# this is not enough to install icons!!! PLEASE FOLLOW THE INSTRUCTIONS IN THE README TO PROPERLY INSTALL ICONS!
After completing the steps in the README to install icons, we can start putting together the MessageInput component in a new file client/src/components/message-input.component.js:

Our layout looks ready. Now let’s make it work!
Let’s start by defining our GraphQL Mutation like we would using GraphIQL:
mutation createMessage($text: String!, $userId: Int!, $groupId: Int!) {
createMessage(text: $text, userId: $userId, groupId: $groupId) {
id
from {
id
username
}
createdAt
text
}
}
That looks fine, but notice the Message fields we want to see returned look exactly like the Message fields we are using for GROUP_QUERY:
query group($groupId: Int!) {
group(id: $groupId) {
id
name
users {
id
username
}
messages {
id
from {
id
username
}
createdAt
text
}
}
}
GraphQL allows us to reuse pieces of queries and mutations with Fragments. We can factor out this common set of fields into a MessageFragment that looks like this:

const createMessage = graphql(CREATE_MESSAGE_MUTATION, {
props: ({ ownProps, mutate }) => ({
createMessage: ({ text, userId, groupId }) =>
mutate({
variables: { text, userId, groupId },
}),

Just like with a GraphQL Query, we first pass our mutation to graphql, followed by an Object with configuration params. The props param accepts a function with named arguments including ownProps (the components current props) and mutate. This function should return an Object with the name of the function that we plan to call inside our component, which executes mutate with the variables we wish to pass. If that sounds complicated, it’s because it is. Kudos to the Meteor team for putting it together though, because it’s actually some very clever code.
At the end of the day, once you write your first mutation, it’s really mostly a matter of copy/paste and changing the names of the variables.

What went wrong? Well technically nothing went wrong. Our mutation successfully executed, but we’re not seeing our message pop up. Why? Running a mutation doesn’t automatically update our queries with new data! If we were to refresh the page, we’d actually see our message. This issue only arrises when we are adding or removing data with our mutation.
To overcome this challenge, react-apollo lets us declare a property update within the argument we pass to mutate. In update, we specify which queries should update after the mutation executes and how the data will transform.

This data comes to us from our Redux store of Apollo data. We check to see if the new Message returned from createMessage already exists (in case of race conditions down the line), and then update the previous query result by sticking the new message in front. We then use this modified data object and rewrite the results to the Apollo store with store.writeQuery, being sure to pass all the variables associated with our query. This will force props to change reference and the component to rerender.
update will currently only update the query after the mutation succeeds and a response is sent back on the server. But we don’t want to wait till the server returns data — we crave instant gratification! If a user with shoddy internet tried to send a message and it didn’t show up right away, they’d probably try and send the message again and again and end up sending the message multiple times… and then they’d yell at customer support!
Optimistic UI is our weapon for protecting customer support. We know the shape of the data we expect to receive from the server, so why not fake it until we get a response? react-apollo lets us accomplish this by adding an optimisticResponse parameter to mutate. In our case it looks like this:

Now that we’re comfortable using GraphQL Queries and Mutations and some tricky stuff in React Native, we can do most of the things we need to do for most basic applications. In fact, there are a number of Chatty features that we can already implement without knowing much else. This post is already plenty long, but there are features left to be built. So with that said, I like to suggest that you try to complete the following features on your own before we move on:
- Add GraphQL Mutations on our server for creating, modifying, and deleting
Groups - Add new Screens to our React Native app for creating, modifying, and deleting
Groups - Build GraphQL Queries and Mutations for our new Screens and connect them using
react-apollo - Include
updatefor these new mutations where necessary
If you want to see some UI or you want a hint or you don’t wanna write any code, that’s cool too! Below is some code with these features added.
