Use prompt on a preset level

[arnedesmedt]

What problem does this feature solve?

Now, if you want to share answers from prompts over multiple vue cli plugins, you need to ask the same question again in each plugin, because prompts are asked on plugin level. Wouldn't it be nice to make this available on preset level, so every plugin in the preset could use the ansers of the preset prompts

What does the proposed API look like?

add a prompst property to the presets json.

You can have a prompt.js in a preset repo and then add plugins using the prompt answers in generator.js.

I'm sorry it seems my initial impression on this issue was incorrect. Currently there's no specific API to achieve this kind of customization.
The corresponding feature request is tracked at #1938
Nevertheless, there's a workaround:

// prompts.js
module.exports = [{
  name: 'useEslint',
  type: 'confirm',
  message: 'use eslint'
}]

// generator.js
const path = require('path')

module.exports = (api, options, rootOptions) => {
  if (options.useEslint) {
    api.extendPackage({
      devDependencies: {
        '@vue/cli-plugin-eslint': '^3.1.5'
      }
    })

    api.onCreateComplete(() => {
      require('child_process').spawnSync(
        'vue',
        [
          'invoke',
          '@vue/cli-plugin-eslint',
          // the following 4 lines can be commented out if you need the plugin prompts
          '--config',
          'standard',
          '--lintOn',
          'save,commit'
        ],
        {
          stdio: 'inherit',
          cwd: path.join(process.cwd(), rootOptions.projectName)
        })
    })
  }
}
