Launching the angular app with the command ng serve -o, we can see the result in the browser: Obviously, this is only an example, we will never call a service directly from a component, right? Return to the server.ts file and import the necessary library: The -D option saves these dependencies as development dependencies, because they are useful only during the development process (in package.json we will find these dependencies in the devDependency block)

npm install -D, for the Typescript definition files for node, body-parse rand express.

Its role is to extract the entire body portion of an incoming request stream and expose it on req.body.

npm install –save body-parser as ExpressJS middleware.

npm install –save express for ExpressJS, the –save option add this required package to our configuration in package.json.As framework for the NodeJS backend we use ExpressJS, which can be installed in our project with following commands: We create a folder “server” in the project root, where we place the backend code, and create in that folder a new file named server.ts. We create a new project with the Angular CLI (for example, with the command ng new angular-node-typescript), and open the project with our preferred code editor, in my case Visual Studio Code: Gulp with the command npm install -g gulp.Typescript with the command npm install -g typescript.Angular CLI with the command npm install -g cli.This is not a problem, but I think it can be interesting to share the setup of an Angular project with Node and Typescript.Īs a first step, we install the prerequisites: Net platform, he asked us to use Typescript for the backend too. The customer accepted the use of Node but, since he knows the. The real execution of the workflow is demanded to a core project written in C++, of course: our job is to create a user interface to create and display the workflow.

After discarding Asp.Net Core, because it does not support ARM processor at the moment, we proposed Angular for the front-end and Node for the backend. A new customer called me for a project on an embedded device, where the purpose is to provide a simple user interface to control the execution of a workflow on the device.
