Last reviewed: November 2024 The preferred way to use environment variables in Netlify is to set them in our environment - be that in the Environment Variables settings UI (on the site’s “Build & Deploy settings” page), or via netlify.toml . You’ll want to choose the right pattern to meet your needs…

Hey!! I tried this and the script runs fine, it seems. But, I can still only access env vars defined manually in my dashboard. I’m trying to access the COMMIT_REF, NODE_ENV, etc. for inside my zip-it-and-ship-it functions. I have this: fs.writeFileSync( './.env', `NODE_ENV=${process.env.NODE_E…

Only environment variables in the dashboard are available at the time of a function execution in Netlify Functions at the time of this answer. :yum:

Ah, ok. So there’s no possibly way to expose COMMIT_REF or even NODE_ENV in functions? Seems like some crucial environment functionality, right? Maybe I’m missing something. For now, I’m checking to see if NETLIFY_DEV exists, and if it does not, then I’m assuming I’m in production. Not my favorite,…

NODE_ENV should be there. Not sure where COMMIT_REF is setup.

Hmm NODE_ENV is undefined. I don’t use netlify-lambda or anything; just the built-in zip-it-and-ship-it. Weird. Hopefully someone can shed some light on this!

Hi @bswank , During the netlify build process you can both modify your function and access en vars, which means you can use a custom webpack plugin, script, etc. to hardcode the environment variables you need in to the functions the same way React automatically hardcodes en vars that start with REAC…

Specifically I want to use the environment variable in the entry property: module.exports = (env = {}) => { console.log(“env $$$$$$$”, env)…

There are probably a million ways, but when I need to populate a file with a value, I do something like this in my build command: sed -i s/PLACEHOLDER/${VARIABLENAME}/g webpack.js && my-usual-build-command This way the value is put in place in the file before I need it. I don’t know how webpack r…

thanks greatly for your help I have added the snippet to my build command in my package.json: “scripts”: { “build”: “sed -i s/PLACEHOLDER/${GAME_ID}/g webpack.config.js && webpack --mode=production --env.production” and the build & deploy run successfully. But my webpack.config.js still cannot s…
