Angular Online IDE & Code Editor for Technical Interviews
Running Angular on CoderPad
This pad is running an Angular app that is served via
ng serve. Changes are automatically captured as you type them, and other people in the pad can see them. You can add as many files to the project as you need, as well as any NPM packages.
To get started, edit the
app.component.html file, and press the Run button to see your changes reload on the right.
The app is pre-configured to support TypeScript, but you can define a
.js file if needed.
IntelliSense is running across your entire project, allowing you to see when there are syntax errors or to get quick hints for how to resolve errors or TypeScript issues.
A shell is provided to you so you can inspect your container in more detail. The shell can be used to install NPM packages using
npm install <package>. In addition to installing packages, the shell can be used for executing a test suite if you have one defined.
⚠️While it’s possible to edit files directly from the shell, we recommend using the editor to make your changes. That way, other people in the pad can see your changes as they’re being made.
Hot Module Reloading
Angular provides hot module reloading by default, meaning that changes you make to the files in your project are automatically applied (after a 2 second debounce); there is no need to refresh the iframe to see the changes. Vite will display any errors directly in the application output, or if there is a system-wide error, in the logs.
Note that changes to certain files (like
index.html) will cause the entire application to reload, while changes to other files (
app.component.ts) will not cause an app reload. The state of the application will be reset whenever the application reloads.
The container running your application has a few limitations. Currently, we don’t limit your CPU usage, though this may change in future. In addition to CPU, we monitor the network bandwidth that is consumed, and limit you to 75 MB for the duration of the container. Finally, we limit the amount of memory accessible to each container to 2 GB.
Out-of-the-box support for SVG files is included, just add a
whatever.svg file and then import it wherever you need it. Other assets will need to be hosted elsewhere and fetched via the shell, or just referenced directly in HTML tags.
