Enable options to load different config files from command-line or npm script about size-limit

Hm. Why do you need different environment? Maybe there is a more simple way.

If you're just looking for cli options you can just disable the internal webpack and manually run your own webpack build.

For example, you can try adding this within your package.json

"scripts": {
  "build": "webpack --config your-custom-config-file.js dist/output.js",
  "size": "npm run build && size-limit"
},
"size-limit": [
  {
     "limit": "300 KB",
     "webpack": false,
     "path": "dist/output.js"
  }
]

Now, npm run size will just run with whatever configuration files you provide.

All config options are available by CLI option. So if you want to have different configs:

size-limit 10 KB app.js --no-webpack 

I think CLI options will be enough.

But I will open this feature request again when somebody will show me use case for different configs.
