How to use babel plugins (dev only)?

[sookoll]

I tried to use babel-plugin-wildcard. JSPM by default load babel and es6 modules into browser and then transpile. I guess that wildcard plugin needs to access file system to determine modules. So only option was server-side transpiling also in development mode. Tried development bundling as described here: https://jspm.io/0.17-beta-guide/development-bundling.html with no luck.

$ jspm install --dev npm:babel-plugin-wildcard

SystemJS.config({
  ...
  meta: {
    '*.js': {
      babelOptions: {
        plugins: ['babel-plugin-wildcard']
      }
    }
  }
});

command to transpile bundle:

$ jspm bundle src/main.js src/build.js -id

It never recognize, that it should use wildcard plugin for transpile imports. Any quidance?

The docs for that plugin show the name of the plugin as "wildcard" when passed to Babel.

Try this (untested):

$ jspm install --dev wildcard=npm:babel-plugin-wildcard

and in your configuration

SystemJS.config({
  meta: {
    '*.js': {
      babelOptions: {
        plugins: ['wildcard']
      }
    }
  }
});
