Step 1: Installation and Configuration
The first step is to create a new Web Connection project. Angular 2 requires a fairly rigid configuration structure that requires some adjustments in order to work smoothly in a Web Connection projects. The following is just one way to do this that follows the way other Web connection projects work. Essentially these steps make a few changes to the Angular 2 Seed Project and building it in place in the Web Connection
We'll start by creating a new Web Connection project called ToDo using the Console.
First we create a project called
ToDo and a process class called
ToDoProcess. These will be the server and process classes respectively:
Next specify the path for the new project and the name of the virtual directory. If you want to install a Root Web folder leave the virtual blank or use
Finally we want to create a REST project which works with JSON by default rather than HTML documents. This produces a wwRestProcess class which turns all return values into a JSON response and can parse incoming JSON objects into FoxPro object:
We'll use the REST service to load and update Todo items, but the main reason for the new project is to get the Web site set up so we can add the Angular functionality added to the Web site.
Note you need to NodeJs and NPM (part of Node) installed in order for the following to work. NodeJs is the build engine and NPM to include the required build components used to build, compile and package the Angular 2 application.
Next we'll add the Angular Seed project template into Web Connection. This is based on the Angular2-Seed project from the Angular site and modified so that it can run in place in the installed folder - the
web folder in this case.
To do this do the following:
- Find the
- Unzip the content of this zip file into your project's
Next we need to install all the support components. Open up a command prompt and change to the
This installs all the configured dev components (languge tools, build server, local web server etc.).
Next check to see if the build process works by running either:
this builds the application. If all is well you shouldn't see any errors here.
At this point you should have a running application that starts with
index.html in the
web folder. You can run this using IIS or IIS Express using a standard URL like http://localhost/todo/index.html.
Because Angular 2 uses Typescript (or ES6) the code needs to be compiled so any code changes require re-running WebPack to recompile the application which is tedious.
During development, a better choice is to use the provided dev server and live reload functionality. To use it run:
Then navigate to http://localhost:3000/.
This runs the local dev server and the webpack file watcher that detects any changes to files in the dev tree and if files change automatically recompiles the app and reloads the current page in the browser.
Now we're ready to start building our Angular application.
