npm install appmanifest
// 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.
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
}
}
}
const parse = require('appmanifest').manifestParser;
npm run dist
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({})
;
