Description
Description
I am trying to use the weaviate-client library in a Cloudflare Worker, but I am encountering issues related to the http2 module. The error message suggests that the http2 package is built into Node.js and is not available in the Cloudflare Workers environment.
Context
I have added the following configuration to my wrangler.toml file to enable Node.js compatibility:
compatibility_date = "2023-12-01"
node_compat = true
However, even with this configuration, I am still facing the http2 related error.
Steps to Reproduce
- Set up a new Cloudflare Worker project.
- Install the
weaviate-clientlibrary using npm or yarn. - Configure
wrangler.tomlwith the appropriatecompatibility_dateandnode_compatsettings. - Write code that uses the
weaviate-clientlibrary to make requests to a Weaviate instance. - Attempt to run the Worker using
wrangler dev.
Expected Behavior
The Cloudflare Worker should be able to use the weaviate-client library to make requests to a Weaviate instance without any issues related to the http2 module.
Actual Behavior
The Worker fails to execute due to the missing http2 module, which is not available in the Cloudflare Workers environment.
✘ [ERROR] Could not resolve "http2"
../../node_modules/.pnpm/@grpc+grpc-js@1.9.14/node_modules/@grpc/grpc-js/build/src/transport.js:20:22:
20 │ const http2 = require("http2");
╵ ~~~~~~~
The package "http2" wasn't found on the file system but is built into node. Are you trying to bundle for node? You can use "platform: 'node'" to do that, which will remove this error.
Possible Solution
One potential solution is to use the native fetch API provided by Cloudflare Workers instead of relying on the http2 module used by the weaviate-client library.
Additional Information
- I'm using Weaviate Cloud
weaviate-clientlibrary version:3.0.0-rc.3

Research direction
Reproduce the failure with a Cloudflare Worker using weaviate-client 3.0.0-rc.3, the shown wrangler.toml settings, and wrangler dev. Start at @grpc/grpc-js/build/src/transport.js, where http2 is required; done means the Worker bundles and can make requests without the missing-module error.
