Provide option to strip comments from JSON files (JSONC) about plugins

[shellscape]

The strip plugin is really meant to only target code, and while it could technically be used on other files, the default filter is '**/*.js'. This is a good opportunity for a new third party plugin, but not a great fit for the strip plugin. Thanks for opening the issue, and please do submit a plugin for this to rollup/awesome if you take that task on.

Yeah, nah.

import { createFilter, dataToEsm } from '@rollup/pluginutils'
import strip from 'strip-json-comments'

export default function json (options = {}) {
  const filter = createFilter(options.include, options.exclude)
  const indent = 'indent' in options ? options.indent : '\t'
  const jsonc = 'jsonc' in options ? options.jsonc : false

  return {
    name: 'json',

    // eslint-disable-next-line no-shadow
    transform (json, id) {
      if (id.slice(-5) !== '.json' || !filter(id)) return null

      return {
        code: dataToEsm(JSON.parse(jsonc ? strip(json) : json), {
          preferConst: options.preferConst,
          compact: options.compact,
          namedExports: options.namedExports,
          indent
        }),
        map: { mappings: '' }
      }
    }
  }
}

Yeah, nah.

import { createFilter, dataToEsm } from '@rollup/pluginutils'
import strip from 'strip-json-comments'

export default function json (options = {}) {
  const filter = createFilter(options.include, options.exclude)
  const indent = 'indent' in options ? options.indent : '\t'
  const jsonc = 'jsonc' in options ? options.jsonc : false

  return {
    name: 'json',

    // eslint-disable-next-line no-shadow
    transform (json, id) {
      if (id.slice(-5) !== '.json' || !filter(id)) return null

      return {
        code: dataToEsm(JSON.parse(jsonc ? strip(json) : json), {
          preferConst: options.preferConst,
          compact: options.compact,
          namedExports: options.namedExports,
          indent
        }),
        map: { mappings: '' }
      }
    }
  }
}

This is really helpful for jsonc used
