watcher script is not compatible with yarn workspaces

[jakubwolny]

After installing typesafe-i18n within one workspace, when you try to run the watcher:
node ./node_modules/typesafe-i18n/node/watcher.js
it does not work, since the files within node_modules are not physically located there (yarn does linking).

node ./node_modules/typesafe-i18n/node/watcher.js
internal/modules/cjs/loader.js:883
 throw err;
 ^

Error: Cannot find module '/Users/jakubwolny/projects/orca/client/node_modules/typesafe-i18n/node/watcher.js'
   at Function.Module._resolveFilename (internal/modules/cjs/loader.js:880:15)

   at internal/main/run_main_module.js:17:47 {
 code: 'MODULE_NOT_FOUND',
 requireStack: []
}

then of course I tried to run it in the directory above (project root), but when it watches entire project, not just single workspace, and paths are all wrong. Or I haven't found a way to tell watcher to specific dir to watch i.e.
node ./node_modules/typesafe-i18n/node/watcher.js --dir=client.
Also, from a perspective of a webpack user, I find it weird that I need to start another file watcher - I already have one (in webpack). So probably it's out of the scope of that issue, but having a webpack plugin could improve a Developer Experience.

So I haven't found any easy way to make it work within yarn workspace. btw. this is the most interesting i18n project I've seen in years I wanted to give a try.

starting the watcher with:
node ../node_modules/typesafe-i18n/node/watcher.js
solved the issue - sometimes the simplest solutions are the best!
still, a webpack plugin could maybe make the adoption a bit easier

Hi @jakubwolny,
thanks for your feedback :)

You can use the outputPath option inside the .typesafe-i18n.json-file to set the output path for the files being generated.

The reason why no webpack plugin exists yet is because I personally use rollup and haven't had the time yet to create one. The node process is currently the fallback for users who aren't using rollup ;)

@jakubwolny as of typesafe-i18n version 2.16.0 you can also start the watcher via a webpack-plugin

oh wow! thank you for the update, I'll definitely try it
