@kingjs/parse-source

Expresses a TypeScript AST as an object literal.

Usage

var assert = require('assert');
var parseSource = require('@kingjs/parse-source');

var ast = parseSource(__filename, { 
  type: true, 
  lines: true,
  character: true
});

var { 
  SourceFile,
  VariableStatement,
  VariableDeclaration,
  CallExpression
} = parseSource;

assert(ast instanceof SourceFile);

var statement = ast.statements[0];
assert(statement instanceof VariableStatement);

var declaration = statement.declarationList[0];
assert(declaration instanceof VariableDeclaration);
assert(declaration.name == 'assert');

var callExpression = declaration.initializer;
assert(callExpression instanceof CallExpression);
assert(callExpression.expression == 'require');
assert(callExpression.arguments[0] == 'assert');

var json = JSON.stringify(ast, null, 2);
console.log(json);

API

parse(path, options)

Parameters

• path: Path to file to a file to parse.
• options: Options to add type, and positioning information to AST.
• options.type: If true, type information is added to the AST as . properties so it'll appear if the AST is serialized to JSON.
• options.line: If true, line numbers are added to the AST.
• options.character: If true, character position is added to the AST.

Returns

Each node of the Typescript AST is stripped down to just those properties that return nodes or are terminal literals.

Install

With npm installed, run

$ npm install @kingjs/parse-source
