There are a few steps to update an Angular application to the latest version:
<ol>
<li>Make sure you have the latest Angular CLI installed. You can install it with:</li>
</ol>
<pre><code class="lang-plaintext">npm install -g @angular/cli@latest
</code></pre>
<ol>
<li>Update your Angular dependencies to the latest version. You'll need to update <code>@angular/core</code>, <code>@angular/cli</code>, and any other Angular libraries your app uses.</li>
</ol>
For example, to update to Angular 12, you would run:
<pre><code class="lang-plaintext">ng update @angular/core@12 @angular/cli@12
</code></pre>
<ol>
<li>Run <code>ng update</code> to update the Angular configuration files like <code>angular.json</code>.</li>
</ol>
<pre><code class="lang-plaintext">ng update @angular/cli
</code></pre>
<ol>
<li>Update any third-party dependencies to compatible versions. Some libraries may require version updates when updating Angular.
</li>
<li>Make any necessary code changes. The Angular Update Guide can help identify any changes needed for your app.
</li>
<li>Build and serve your application to test for any errors. Resolve any build errors or warnings.
</li>
</ol>
<pre><code class="lang-plaintext">ng build
ng serve
</code></pre>
<ol>
<li>If needed, update from <code>HttpModule</code> to <code>HttpClientModule</code> and switch to pipeable RxJS operators.</li>
</ol>
Some other tips:
<ul>
<li>Update to the latest Angular version as soon as possible to minimize required code changes.
</li>
<li>Keep a watch on deprecated features and plan changes ahead of time.
</li>
<li>Use the <code>--force</code> and <code>--allow-dirty</code> flags with <code>ng update</code> if needed.
</li>
</ul>
