Load Config at runtime

[Rigo-m]

Using c12 to load configs at build time/in nodejs environment is trivial.

But what if I want to then use the config as a central piece of my application at runtime?

E.g.: I'm publishing a function in a worker that needs to read from loaded config some settings. At build time I should resolve the final config and bundle it, right? Should I use a vite plugin to do this?

Yes you might. However consider you cannot serialize (back) everything only basic values with JSON.stringify or more advanced with libraries like devalue.

One simpler alternatieve is that you directly bundle source config using vite as it supports ts.

Thank you @pi0, is there any example out there on how to bundle the config with vite?

[pi0]

i think basically importing it as a file? (nuxt app config is based on same idea)

[Rigo-m]

So instead of using loadConfig you just import the config. That makes sense, but extending the config wouldn't work in this case, correct?

[pi0]

so the question is how you wanted to extend the config. it can be with runtime hooks for example like nuxt plugins allow.

Since bundled code runs in all envs including browser, environment variables are not probably suitable.
