How do I upgrade all scoped packages with Yarn?

Issue

Is it possible to upgrade all specific scoped packages in the dependencies section of my package.json by using the Yarn package manager?

For example:

yarn upgrade @scope/* 

This will upgrade all scoped packages in yarn.lock and package.json file.

Solution

Since there’s no way to do this currently with Yarn, I’ve written a very short Node script to do what you want:

var fs = require('fs');
var child_process = require('child_process');

var filterRegex = /@angular\/.*/;

fs.readFile('./package.json', function(err, data) {
    if (err) throw err;

    var dependencies = JSON.parse(data)['dependencies'];
    Object.keys(dependencies).forEach(function(dependency) {
        if (filterRegex.test(dependency)) {
            console.log('Upgrading ' + dependency);
            child_process.execSync('yarn upgrade ' + dependency);
        } else {
            console.log('Skipping ' + dependency);
        }
    });
});

Here’s a quick explanation of what that does:

• it loads the package.json from the directory that the terminal is currently in

• we then parse the JSON of the package.json and get the "dependencies" key

• for each dependency, we run the regex specified as the filterRegex (if you need to change this or want an explanation of the regex syntax, I would test with RegExr. I used @angular as an example prefix for the regex)

• if the dependency matches, we run yarn upgrade [DEPENDENCY] and log it

• otherwise, we log that it was skipped.

Let me know if you have any trouble with this, but it should solve your issue until the Yarn team come up with something better.
