Part 0: Overview

Overview

For the best experience with this tutorial, review these requirements to make sure you have what you need to be successful.

Experience

This tutorial assumes that you have experience with the following:

• Creating Web pages by editing the HTML directly.

• Programming Web site content in JavaScript.

• Reading Cascading Style Sheet (CSS) content and understanding how selectors are used.

• Using command-line instructions to perform tasks on your computer.

• (optional, nice to have) Some familiarity with Angular.

Equipment

The tutorial can be completed by using a local installation of the Angular tools or by using StackBlitz in a Web browser. Local Angular development can be completed on Windows, MacOS or Linux based systems.

Concept Preview

This tutorial will create an Angular app that displays an inbox with the list of Requests assigned to the logged on user in ProcessMaker and renders the form as defined in the ProcessMaker form builder, complete with JavaScript and CSS.

Local Development Environment

Perform these steps in a command-line tool on the computer you want to use for this tutorial.

Step 1: Identify the Version of node.js that Angular Requires

Angular requires an active LTS or maintenance LTS version of Node. Let's confirm your version of node.js. For information about specific version requirements, see the engines property in the package.json file.

From a Terminal window:

1. Run the following command: node --version.

2. Confirm that the version number displayed meets the requirements.

Step 2: Install the Correct Version of node.js for Angular

If you do not have a version of node.js installed, please follow the directions for installation on nodejs.org.

Step 3: Install the Latest Version of Angular

After node.js and npm are installed, install the Angular CLI which provides tooling for effective Angular development.

From a Terminal window run the following command:

npm install -g @angular/cli.

Step 4: Install Integrated Development Environment (IDE)

Use any tool you prefer to build apps with Angular. We recommend the following:

1. Visual Studio Code.

2. As an optional, but recommended step, you can further improve your developer experience by installing the Angular Language Service.

Review

In this part, you learned about the app that you build in this tutorial and prepared your local computer to develop Angular apps.
