Google Closure Compiler does not support 'Wildcard export' (original) (raw)

[REQUIRED] Describe your environment

[REQUIRED] Describe the problem

Closure compiler does not support ES6 Wildcard export.
The file at /node_modules/@firebase/util/dist/esm/index.js, does at the moment use Wildcard export.

As a Google product, it may be a good ideer to support the Google Closure Compiler.
This could maybe be solved easily by using the angular/tsickle project, when compiling TS to JS.

Another quick fix could be to declare alle the export manually.
index.ts

export { assert, assertionError } from './src/assert'; export { base64, base64Decode, base64Encode } from './src/crypt'; export { CONSTANTS } from './src/constants'; export { deepCopy, deepExtend, patchProperty } from './src/deepCopy'; export { Deferred } from './src/deferred'; export { getUA, isMobileCordova, isNodeSdk, isReactNative } from './src/environment'; export { ErrorFactory, ErrorList, FirebaseError, patchCapture, StringLike } from './src/errors'; export { jsonEval, stringify } from './src/json'; export { decode, isAdmin, issuedAtTime, isValidFormat, isValidTimestamp } from './src/jwt'; export { clone, contains, every, extend, findKey, findValue, forEach, getAnyKey, getCount, getValues, isEmpty, isNonNullObject, map, safeGet } from './src/obj'; export { querystring, querystringDecode } from './src/query'; export { Sha1 } from './src/sha1'; export { async, CompleteFn, createSubscribe, ErrorFn, Executor, NextFn, Observable, Observer, PartialObserver, Subscribe, Unsubscribe } from './src/subscribe'; export { errorPrefix, validateArgCount, validateCallback, validateContextObject, validateNamespace } from './src/validation'; export { stringLength, stringToByteArray } from './src/utf8';

Closure Compiler output message:

./node_modules/@firebase/util/dist/esm/index.js:30:
Originally at:
node_modules/@firebase/util/dist/index.ts:31: ERROR - ES6 transpilation of 'Wildcard export' is not yet implemented.

Steps to reproduce:

All I have done in my Angular project is to import 'firebase/app' and initialize.

import { initializeApp } from 'firebase/app';

const app = initializeApp( { apiKey: /* apiKey /, authDomain: / authDomain*/, databaseURL: /* databaseURL*/, projectId: /* projectId*/, storageBucket: /* storageBucket*/, messagingSenderId: /* messagingSenderId*/ } );

In Closure Compiler config have I added all the needed files (package.json and js).
