Prerequisites for Getting Started with Angular QR Code Generation
Before diving into QR code generation with Angular, ensure you meet these prerequisites:
Foundational TypeScript Knowledge: Familiarity with TypeScript and Object-Oriented concepts, including TypeScript classes and decorators, is essential for this tutorial.
Local Development Environment: Make sure you have a local development machine with Node.js 10+ and NPM 6+ installed. Node.js is a core requirement for Angular CLI and many frontend tools. You can download Node.js from the official website or follow system-specific instructions for installation. An efficient way to manage Node.js versions is by using NVM (Node Version Manager), a POSIX-compliant bash script.
Note: If you prefer not to set up a local environment for Angular development but still want to explore the code from this tutorial, you can use Stackblitz. Stackblitz is an online Integrated Development Environment (IDE) for frontend development, enabling you to create Angular projects compatible with Angular CLI seamlessly.
By presenting the prerequisites in a more SEO-friendly manner, you enhance the tutorial's search engine visibility and readability for your audience.
Step 1 — Installing Angular CLI
Installing Angular CLI
Major versions of Angular CLI follow the supported major version of Angular, but minor versions can be released separately.
Install the CLI using the npm package manager:
npm install -g @angular/cli
Step 2 — Creating a New Angular App
To create, build, and serve a new, basic Angular project on a development server, go to the parent directory of your new workspace use the following commands:
ng new my-first-project
The Angular CLI will prompt you with a couple of questions:
To add Angular routing, type 'y' for Yes.
Choose your preferred stylesheet format (e.g., CSS).
Open your web browser and navigate to the http://localhost:4200/ address to see your app running.
Step 2 — Install qr-code pakage provider : @techiediaries/ngx-qrcode
npm i @techiediaries/ngx-qrcode
