running demoparser in aws lambda (or: including binaries for another platform than current platform)

[danielfyhr]

hi,

i want to run demoparser both locally and on aws Lambda, and I have a hacky solution. i'm wondering if it's possible to solve this in a more graceful manner.

current setup

• local development: macos arm64 using @laihoe/demoparser2-darwin-arm64
• aws lambda: linux arm64 requiring @laihoe/demoparser2-linux-arm64-gnu

current solution

to add the linux binary to my package.json from my mac, i have to run:

npm install @laihoe/demoparser2-linux-arm64-gnu --force

The --force flag is required to bypass this error:

53 verbose stack Error: Unsupported platform
53 verbose stack at checkPlatform (/Users/danielfy/.nvm/versions/node/v18.19.0/lib/node_modules/npm/node_modules/npm-install-checks/lib/index.js:55:25)
53 verbose stack at #checkEngineAndPlatform
...

then i use esbuild to copy .node files so my code package looks like this for the lambda function:

demoparser2.darwin-arm64-M4AIRYHZ.node
demoparser2.linux-arm64-gnu-SPGLXOPY.node
main.mjs

questions

1. is there a way to handle this more elegantly? for example, other packages like ffmpeg-static handle multiple platforms seamlessly without requiring --force flags or platform-specific installations.
2. is it possible to bundle multiple platform binaries in a single package?
