Project Modules

There are no modules declared in this project.

to-ast

This module converts JavaScript objects to an equivalent abstract syntax tree representation, compatible with the Mozilla Parser API. You can use it to generate JavaScript source code from objects, using escodegen.

Usage

Install with npm:

npm install to-ast

Here's a simple example:

var toAST = require('to-ast');
var escodegen = require('escodegen');

// get an AST from a number...
toAST(2) //=> { type: 'Literal', value: 2 }

// or if you want a source string...
escodegen.generate(toAST(2)) //=> '2'

Supported types

• undefined
• null
• number, string, and boolean literals
• functions
• Node buffers
• arrays
• String, Number, and Boolean object wrappers
• typed arrays and array buffers
• dates
• errors
• regular expressions
• object literals

Custom types

Most built-in JavaScript types as supported out of the box, but if you want to override the behavior for your particular object, you can provide a toAST method on your object:

var toAST = require('to-ast');
var escodegen = require('escodegen');

function Person(name) {
  this.name = name;
}

Person.prototype.toAST = function() {
  return {
    type: 'NewExpression',
    callee: { type: 'Identifier', name: 'Person' },
    arguments: [{ type: 'Literal', value: this.name }]
  };
};

escodegen.generate(toAST(new Person('Devon'))) //=> "new Person('Devon')"
