While using package with docker desktop

[deepakkatara]

HI Team,

On macOS, I use the snappy package, which is successful. however, the moment I attempt to launch the project locally using Docker Desktop, an issue occurs while starting the container-

`Error: Cannot find module '@napi-rs/snappy-linux-x64-musl'
Require stack:

• /code/node_modules/snappy/index.js
• /code/dist/server/index.js

  requireStack: [

  '/code/dist/server/index.js',
  '/code/index.js'
  ]
  }`

The potential problem that I see is connected to optionalDependencies because it only installs @napi-rs/snappy-darwin-x64 compatible with Mac and searches for Linux @napi-rs dependencies when I run it in a docker container.

Docker info

What could be the potential solution of this?

@deepakkatara you are supposed to re-install your dependencies in your docker environment

[deepakkatara]

I also tried

-- Install snappy package using yarn and include Linux support
RUN yarn add snappy --build-from-source --frozen-lockfile --production=false -- --with-pic

[Brooooooklyn]

The COPY . . is after yarn install, so your installed node_modules in Docker is overridden by the host node_modules.

I'm getting the same issue, and I think it's because my local arch is different than the docker arch. So my package-lock.json file has this:

    "node_modules/snappy/node_modules/@napi-rs/snappy-darwin-arm64": {
      "version": "7.2.2",
      "cpu": [
        "arm64"
      ],
      "license": "MIT",
      "optional": true,
      "os": [
        "darwin"
      ],
      "engines": {
        "node": ">= 10"
      }
    },

while the Docker runtime (node:18-alpine) needs @napi-rs/snappy-linux-arm64-musl. But I only want to run npm ci in the docker container, not npm i. Maybe I could manually detect which one it needs and install that specific engine? Thoughts, @Brooooooklyn?

@eabrouwer3 see npm/cli#4828

You can remove node_modules and package-lock.json and re-generate the package-lock.json

[eabrouwer3]

I ended up adding all of the runtimes as optional dependencies, so that no matter where I'm running npm ci from, I get all of them.
