[gatsby-plugin-graphql-codegen] ExperimentalWarning: stream/web is an experimental feature about gatsby-typescript HOT 3 CLOSED

I've confirmed that I no longer experience this issue with v3.1.1. This issue can be closed.

from gatsby-typescript.

Running cross-env GATSBY_GRAPHQL_IDE=playground NODE_OPTIONS="--trace-warnings" gatsby develop --verbose produces the following output:

 ERROR

This appears to be a problem with the @graphql-tools/url-loader library based on the trace information. The line in question within this library is an import:

const crossUndiciFetch = require('cross-undici-fetch');

cross-undici-fetch requires stream/web in https://github.com/ardatan/w3-server/blob/master/packages/cross-undici-fetch/dist/node-ponyfill.js on line 31. This library was introduced in this commit of @graphql-tools/url-loader.

gatsby-plugin-graphql-codegen currently has v7.0.0 (i.e. ^7.0.0 with the current version at v7.7.1) of the @graphql-tools/url-loader as a dependency and is used in packages/gatsby-plugin-graphql-codegen/src/gatsby-node.ts. Latest commit for this is 8219851 on Oct 28, 2021. Before that on commit e68b6d5, @graphql-tools/url-loader was at v6.10.1.

It seems the folks in the @graphql-tools team thought it was a good idea to use an experimental feature for a production release. Until these upstream issues are resolved, the current solution should be for devs to rollback their gatsby-plugin-graphql-codegen dependencies to v3.0.0 or the latest v2 if possible. I can confirm that rolling back to v3.0.0 (exact version only) resolves this error, albeit with the following warning:

warn Plugin gatsby-plugin-graphql-codegen is not compatible with your gatsby version 4.6.0 - It requires gatsby@^3.0.0

As far as this project goes, the @graphql-tools/url-loader version should be rolled back to the last one that does not use cross-undici-fetch, namely v7.4.2.

Edit: I forgot to mention that this issue prevents gatsby-plugin-graphql-codegen from working for me unless I rollback to v3.0.0.

Edit2: Confirmed that stream/web is still experimental as of the most recent version of Node (v17.4.0) as indicated here.

Environment:

• Windows 10
• Gatsby v4.6.0
• TypeScript v4.5.5
• Node v16.13.0
• gatsby-plugin-graphql-codegen v3.1.0
