i am trying to create a file .json or .text in angular and put it in path : /assets.

after searching for a while all result is to get data from file:

we can get data from file using this methode:

this.httpClient.get("assets/data.json").subscribe(data =>{
  console.log(data);
})

But how to post and create a new file data.json and put it in assets?

Browsers aren't allowed to simply write to files to the server. If that was possible, the Google homepage would be vandalised 30 times a second.

You need to write a web service (in the programming language of your choice, which could be JavaScript or TypeScript if you arrange to have a server on which you can use Node.js).

You probably want to write the data somewhere other than assets (which sounds like a directory that is part of the built Angular application and not a user data directory) and you probably should be using a database rather than using JSON file (databases are efficient and deal with simultaneous writes easily) — your web service can have another endpoint that reports the contents of the database as JSON.

Once you have a web service, then you can make a POST or PUT request to the URL for it using @angular/common/http as described in the Angular guide.
