bower-json

Read bower.json files with semantics, normalisation, defaults and validation.

Usage

.read(file, callback)

Reads file and applies normalisation, defaults and validation according to the bower.json spec.
If the passed file does not exists, the callback is called with error.code equal to ENOENT.
If the passed file contents are not a valid JSON, the callback is called with error.code equal to EMALFORMED.
If the json does not comply with the bower.json spec, the callback is called with error.code equal to EINVALID.

var bowerJson = require('bower-json');

// Can also be used by simply calling bowerJson()
bowerJson.read('/path/to/bower.json', function (err, json) {
    if (err) {
        console.error('There was an error reading the file');
        console.error(err.message);
        return;
    }

    console.log('JSON: ', json);
});

.parse(json, callback)

Parses an object. Useful when you want to apply normalisation, defaults and validation directly to an object.
If the json does not comply with the bower.json spec, the callback is called with error.code equal to EINVALID.

var bowerJson = require('bower-json');

var json = {
    name: 'my-package',
    version: '0.0.1'
};

bowerJson.parse(json, function (err, filename) {
    if (err) {
        console.error('There was an error parsing the object');
        console.error(err.message);
        return;
    }

    console.log('JSON: ', json);
});

.find(folder, callback)

Finds the json filename inside a folder.
Checks if a bower.json exists, falling back to the deprecated component.json.
If no file was found, the callback is called with a error.code of ENOENT.

var bowerJson = require('bower-json');

bowerJson.find('/path/to/folder', function (err, filename) {
    if (err) {
        console.error('There is no json file in the folder');
        return;
    }

    console.log('Filename: ', filename);

    // Now that we got the filename, we can read its contents
    bowerJson.read(filename, function () {
        if (err) {
            console.error('There was an error reading the file');
            console.error(err.message);
            return;
        }

        console.log('JSON: ', json);
    });
});
