Firebase用于测试和生产的独立firebase.json文件-使用Angular环境文件变量吗？

Question

The settings for Firebase deployment - Firestore, Hosting, and Cloud Functions - are in the firebase.json file. Does anyone know a way to have 2 separate firebase.json files - one for test and one for prod ? Or use variables which are configurable? My project is Angular so my first idea was to use the environments variables which are referenced during the build process - test and prod. Is this possible?

My specific goal is to use a different set of firebase.rules for test and production . I want to specify a firebase.prod.rules file for example when deploying to production. This technique can be useful for changing firebase indexes file or hosting test vs prod project differences for which there are many configuration options available in the firebase.json file.

"firestore": {
    "indexes": "firestore.indexes.json",
    "rules": "firestore.rules"
}

You can make a config file and put it in your assests.

From your assests you import it to your ngModule and get the value of the string with the http.

After this you build your project and change the config file. Now change it back for the serve. And you keep the build config file, never copy it again to the build location.

Check out Dynamic module/service configuration and AOT for an example.

public getEnvironment(): Promise<string> { return new Promise<string>(resolve => { let me = this; this.http.get('./config.json') .map(res => res.json()) .toPromise() .then((config) => { resolve(config.url); }); }); }

Your config file look something like:

{"url": ""}
