ReferenceError: window is not defined in NodeJS environment

[jhlabs]

Expected Behavior

I expect to be able to launch the Dapr Javascript SDK in a NodeJS environment when running in a Docker container.

Actual Behavior

My different Typescript services that import the Dapr JS SDK launch just fine in my local environment. As soon as I try to run them packaged in a Docker Container I receive the following error on startup:

I don't have a great explanation for that. It seems that the Dapr SDK somehow thinks it is in a browser environment and therefore requires modules like window?

Steps to Reproduce the Problem

Package any application that uses the Dapr JS SDK in a Docker container and run the container.

Hi, this looks like an issue due to the protobuf library that we're using, see protocolbuffers/protobuf-javascript#8. There is a workaround mentioned in it, does that work for you?

[jhlabs]

@shubham1172 thanks for the quick reply. I tried using this workaround but still encountered the issue. It is unfortunately also not workable for all our services since we use Sveltekit that can run on both server and client. Using this workaround broke the build for Sveltekit.

[rzyns]

In protocolbuffers/protobuf-javascript#8 (comment) the workaround is this:

// @ts-ignore
globalThis.window = null;
// @ts-ignore
globalThis.self = null;

@jhlabs, in case you haven't tried it already, how about something like this? 🤔

// @ts-ignore
if (typeof window === 'undefined') globalThis.window = null;
// @ts-ignore
if (typeof self === 'undefined') globalThis.self = null;

That shouldn't interfere with Sveltekit
