В настоящее время у меня есть monorepo, где у меня есть два (+) пакета, использующих рабочие пространства пряжи:
root
/packages
/common
/web
...
root/package.json
...
"workspaces": {
"packages": [
"packages/*"
],
"nohoist": [
"**"
],
},
web - простое приложение create-реагировать с шаблоном машинописи. У меня есть некоторый код TS в common, который я хочу использовать в web, но кажется, что CRA не поддерживает компиляцию кода вне src, что выдает ошибку при попытке импортировать из common в web:
../common/state/user/actions.ts 4:66
Module parse failed: Unexpected token (4:66)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders
| import { UpdateUserParams } from './reducer';
|
> export const login = createAction('USER/LOGIN')<{ username: string; password: string }>();
Таким образом, я следовал инструкциям на в этом комментарии после исключения включения путей в /common, но, похоже, babel-loader загружает файлы, но теперь это не так. не компилирую их из машинописного текста:
./common/state/user/actions.ts
SyntaxError: /Users/brandon/Code/apps/packages/common/state/user/actions.ts: Unexpected token, expected "," (4:66)
2 | import { UpdateUserParams } from './reducer';
3 |
> 4 | export const login = createAction('USER/LOGIN')<{ username: string; password: string }>();
| ^
5 |
6 | export const logout = createAction('USER/LOGOUT')();
Как я могу получить webpack / babel для правильной компиляции общего кода? Я знаю, что могу common скомпилировать его собственный код, но мне бы не пришлось перекомпилировать общий код каждый раз, когда я хочу внести изменение. Для каждого приложения это идеально.
