Angular Parser

Parse Angular source into structured metadata without uploading code. Extract artifact type, decorators, selectors, imports, providers, inputs, outputs, injected services, signals, routes, lifecycle hooks, template bindings, and form-control details as readable JSON.

Developer Input

Angular parser input

Angular source code

import { Component, Input, inject, signal } from '@angular/core';
@Component({selector:'app-profile',standalone:true,templateUrl:'./profile.html'})
export class ProfileComponent {
  @Input() userId!: string;
  private api = inject(ApiService);
  loading = signal(false);
  ngOnInit() { this.load(); }
  load() {}
}

How to use this developer tool

Paste a component, service, directive, pipe, route, or module.
Select the parsing depth.
Choose whether to extract dependencies and template bindings.
Run the parser and copy or download the JSON result.

What this developer tool does

The parser detects common Angular declarations and returns a structured summary that is useful for documentation, code review, and dependency inspection.

Detect artifact type → extract imports and decorators → parse metadata and class members → collect Angular APIs → serialize results as JSON.

Dynamic decorator metadata and runtime-generated values are reported as partial static-analysis results.

Example

A component using @Input, inject(), signal(), and ngOnInit is converted into JSON arrays for inputs, dependencies, signals, and lifecycle hooks.

Tips for better output

Use Detailed mode for class members and lifecycle hooks.
Use Dependency Analysis for imports and injected services.
Review duplicate matches in heavily metaprogrammed code.
Export JSON for documentation workflows.

FAQ

How do I parse Angular component metadata online?

Paste the component and run the parser to extract its decorator, selector, imports, template, and style references.

Can I extract Angular inputs and outputs as JSON?

Yes. Common @Input, @Output, input(), and output() declarations are listed in the JSON result.

How do I list injected services in an Angular component?

Enable dependency extraction to detect constructor injection and inject() calls.

Can the parser read Angular route definitions?

Yes. It extracts common path, component, redirect, guard, resolver, and lazy-load patterns.

Does the Angular Parser generate a real compiler AST?

No. It performs static pattern analysis suitable for quick inspection and documentation.
