Angularjs: write json data to file

Question

Simple question, is it possible to write json data (received from API) to a json file in my directory structure. The api returns a json string. Is there any method in angular that supports this or do I need to rely on jquery? Extra information on this topic is welcome.

It's not possible for Angular (or any other client-side code) to write a file onto specific place at the client machine. While there's Filesystem API, it's basically about giving filesystem aliases to the data stored in the browser's context. — raina77ow

You cannot access the user's filesystem from javascript, instead you should present the user with a save dialog (it's up to the user where to save the file). AngularJS doesn't support this out of the box, you could however save a file to the default download folder by converting the JSON to a base64 string and bind it to an a href.

<a href="data:application/octet-stream;charset=utf-16le;base64,ew0KICAgICJnbG9zc2FyeSI6IHsNCiAgICAgICAgInRpdGxlIjogImV4YW1wbGUgZ2xvc3Nhcnki

For more control to save files to the client, you could use FileSaver which has support for older browsers.
