What is @schematics/update?

@schematics/update is a package used for updating dependencies and managing migrations in Angular projects. It provides a set of tools to automate the process of updating dependencies and applying necessary code changes.

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', {}),
  ]);
}

npm-check-updates is a utility that automatically adjusts a package.json with the latest version of all dependencies. It is similar to @schematics/update in that it helps manage dependency updates, but it does not provide migration capabilities.

renovate

Renovate is a tool for automating dependency updates. It creates pull requests for updates and can be configured to handle complex update scenarios. Unlike @schematics/update, Renovate focuses on automating the entire update process, including CI/CD integration.

greenkeeper

Greenkeeper is a service that keeps your npm dependencies up to date. It monitors your dependencies and creates pull requests when updates are available. Similar to @schematics/update, it helps manage dependency updates but does not handle migrations.
