Try it online -

https://boopathi.in/appmanifest/

This project is still under active development. Ideas and contributions welcome :)

Install

npm install appmanifest

Usage

API

// result is the processed manifest object
var result = manifestParser({
  manifest: "<manifest json string>",
  manifestUrl: "https://example.com/manifest.json", // this is required to validate some urls
  documentUrl: "https://example.com/" // this is also required to validate some urls
  logger: function() { return { warn() {}, error(){}, log(){} } } // optional
});

If you don't want to pass manifestUrl and documentUrl, just use example.com urls as mentioned above.

Capture errors and warnings

You can pass your custom logger and capture all errors and warnings to compile and display later. The signature of the logger function is this.

function Logger (name /* name of the param currently validated */) {
  return {
    warn(message) {
      // do your stuff
    },
    error (message) {
      // do your stuff
    },
    log (message) {
      // do your stuff
    }
  }
}

Node

const parse = require('appmanifest').manifestParser;

Browser

  1. You can bundle this with webpack / browserify
  2. Generate your dist - npm run dist
  3. Get it from CDN - https://npmcdn.com/appmanifest@latest/dist/manifest-parser.min.js

The library when obtained as a built bundle, exports UMD with ManifestParser as the name.

Note:

If you're using the cdn URL, you need to use ManifestParser.default({});

  • Served over HTTPS
