svelte_ast

Parser and utilities for the SvelteDart template compiler. Based on the original Svelte 5 (v5.16.6) parser. Top-level scripts, styles and template expressions are parsed using analyzer and `csslib.

Usage

import 'dart:convert';

import 'package:svelte_ast/svelte_ast.dart';
import 'package:svelte_ast/mirror_mapper.dart';

const String content = '''
<script>
  int count = 0;
</script>

<button on:click="{() => count++}">count: {count}</button>''';

void main() {
  // Create an AST tree by parsing a template.
  Root root = parse(content);

  // Print to console.
  print(const JsonEncoder.withIndent('  ').convert(root.toJson(mapper)));
}
