Cannot find package 'ws' imported from '@solana/rpc-subscriptions-transport-websocket/...'

[lithdew]

Overview

I tried to build and run a Vite project using @solana/web3.js@rc in Docker. I tried the docker images gcr.io/distroless/nodejs22-debian12 and node:22-slim and ran into the same error.

The error:

$ docker run -e DATABASE_URL=$DATABASE_URL -p 3000:3000 web
node:internal/modules/esm/resolve:839
  throw new ERR_MODULE_NOT_FOUND(packageName, fileURLToPath(base), null);
        ^

Steps to reproduce

The Dockerfile:

# syntax = docker/dockerfile:1

# Adjust BUN_VERSION as desired
ARG BUN_VERSION=1.1.22
FROM oven/bun:${BUN_VERSION}-slim as base

# Install packages needed to build node modules
RUN --mount=type=cache,id=cache,target=/var/cache/apt \
    --mount=type=cache,id=lib,target=/var/lib/apt \
    apt-get update -qq && \
    apt-get install --no-install-recommends -y unzip

LABEL fly_launch_runtime="Bun"

WORKDIR /app

ENV NODE_ENV="production"

# Throw-away build stage to reduce size of final image
FROM base as build

# Install node modules
COPY --link bun.lockb package.json ./
RUN --mount=type=cache,id=bun,target=/root/.bun \
    bun install --frozen-lockfile

# Copy application code
COPY --link . .

# Build application
RUN bun run build

# Final stage for app image
FROM gcr.io/distroless/nodejs22-debian12 AS run

LABEL fly_launch_runtime="Node.js"

WORKDIR /app

ENV NODE_ENV="production"

COPY --from=build /app/.output ./

# Start the server by default, this can be overwritten at runtime
EXPOSE 3000
CMD ["./server/index.mjs"]

Let me know if you need a full reproduction.

Description of bug

'ws' should be resolved inside of @solana/rpc-subscriptions-transport-websocket in a NodeJS environment.

I'm wondering if this could be a bun issue wrt resolving the dependencies. I haven't used bun before and I'm not aware of anyone having used it with web3js yet.

If you could provide a complete repro that'd be really helpful, since I don't think any of us have anything similar yet.

Can you also clarify whether you've tested this with bun outside of Docker? Or are you only using bun in the Dockerfile? It'd be good to narrow this down to bun or the Docker image as a starting point.

Do you have peer = false configured in your bunfig?

https://bun.sh/docs/runtime/bunfig#install-peer

ws is a peer dependency; if you have auto-install-peers disabled, this would explain why it's missing.

Feel free to reopen this if that's not the case.
