What is the angular compiler?
How does the angular compiler work?
Assuming you are referring to the Angular 2+ compiler, in short, it takes your files and turns them into something the browser can understand. This is done through a few steps:
Parsing/tokenizing – The compiler takes your HTML and CSS and converts them into tokens. These tokens are then turned into an Abstract Syntax Tree (AST).
Angular-specific optimizations – The compiler then performs various optimizations specifically for Angular, such as reducing unnecessary code, creating faster render functions, etc.
The Angular compiler is an ahead-of-time (AOT) compiler. This means that it compiles your Angular project before the browser downloads and runs your code. The benefits of AOT compilation include smaller bundle sizes, faster render times, and improved security.
When the browser loads your compiled Angular project, the first thing that happens is that the bootstrap code is executed. This bootstrap code initializes the Angular framework and starts up your application. After the bootstrap code has run, your application’s main() method is executed and your application begins running!
What are the benefits of using the angular compiler?
- Allows for better performance – AOT-compiled code runs faster than JIT-compiled code because it is already in the native machine code format. This means that there is no need for the browser to interpret and compile the code on the fly, as it does with JIT-compiled code.
- Generates smaller bundles – Because AOT compiled code is already in the native machine code format, it doesn’t need to be bundled with an interpreter or compiler. This results in smaller application bundles, and also eliminates the need to download and install a separate AngularJS compiler package on the server.
How do I use the angular compiler?
The Angular compiler is also responsible for optimizing your code so that it runs more efficiently. For example, the compiler will remove unused code and make sure that your code doesn’t have any errors.
If you’re using the Angular CLI to build your project, the CLI will automatically call the Angular compiler when you make changes to your files.
There are two ways to use the Angular compiler:
- Use the Angular CLI to compile your code.
- Use the Angular Compiler API to compile your code.
An Angular compiler is a powerful tool that can help developers create web and mobile applications faster and with fewer errors. By understanding how the compiler works, developers will gain a better knowledge of the code they are writing, which in turn helps them debug issues more quickly and efficiently. The Angular compiler also allows for the optimization of code to improve performance, making it an indispensable part of any developer’s workflow. Whether you’re developing web or mobile app platforms, understanding how the Angular compiler works can help you write cleaner code and create better applications overall.
