Trivial webpack plugin / inline function to fail build if something is imported

super-deprecate.ts

/**
 * Put in webpack's resolve.plugins[], direct reference.
 * For example, `resolve: { plugins: [superDeprecate] }`.
 * 
 */
function superDeprecate(this: any) {
  // request is the module name as written in the "import" declaration/expression / "require" call
  // issuer is the absolute path to the file making the request
  // I don't remember what path is
  interface ResolveQuery {
    context: {
      issuer: string
    }
    path: string
    request: string
  }

  this.hooks.resolve.tapPromise(
    'super-deprecate',
    async ({ context: { issuer }, request }: ResolveQuery) => {
      if (/\bjquery\b/.test(request)) {
        throw new Error(
          "Don't import 'jquery' or modules that depend on it."
        )
      }
      if (/\bhandlebars\b/.test(request)) {
        throw new Error("Don't import 'handlebars' from spa.")
      }
      if (/\bhooks[\\/]legacy\b/.test(request)) {
        throw new Error('Legacy hooks are only allowed in non-spa components.')
      }
    }
  )
}
