What are @schematics/update's main functionalities?

Update Dependencies

This feature allows you to update the version of a dependency in the package.json file and install the updated packages.

const { NodePackageInstallTask } = require('@angular-devkit/schematics/tasks');
const { updateJsonFile } = require('@schematics/update');

function updateDependencies() {
  return (tree, context) => {
    updateJsonFile(tree, 'package.json', json => {
      json.dependencies['some-package'] = '^2.0.0';
    });
    context.addTask(new NodePackageInstallTask());
    return tree;
  };
}

Apply Migrations

This feature allows you to apply code migrations to your project, ensuring that your codebase is compatible with the updated dependencies.

const { chain } = require('@angular-devkit/schematics');
const { runSchematic } = require('@schematics/update');

function applyMigrations() {
  return chain([
    runSchematic('migration-schematic', {}),
  ]);
}
