management.getPermissionWarningsByManifest()

Given the text of a manifest.json file, this function returns the permission warnings that would be given for the resulting add-on, as an array of strings.

This API does not require the "management" API permission.

This is an asynchronous function that returns a Promise.

Syntax

var gettingWarnings = browser.management.getPermissionWarningsByManifest(
  manifestString      // string
)

Parameters

manifestString

string. String containing the manifest file. This must be a valid manifest: for example, it must contain all the mandatory manifest keys.

Return value

A Promise that will be fulfilled with an array of strings, each of which contains the text of a permission warning.

Examples

Log the permission warnings for the given manifest file:

var manifest = {
  "manifest_version": 2,
  "name": "test",
  "version": "1.0",
  "permissions": ["management", "<all_urls>"]
}

var manifestString = JSON.stringify(manifest);

function gotWarnings(warnings) {
  console.log(warnings);
}

function gotError(error) {
  console.log(`Error: ${error}`);
}

var gettingWarnings = browser.management.getPermissionWarningsByManifest(manifestString);
gettingWarnings.then(gotWarnings, gotError);
