parser-front-matter

Front matter parsing middleware based on gray-matter.

Install

Install with npm:

1$ npm install --save parser-front-matter

This is similar to a consolidate.js engine, but for parsing. Works with assemble, verb, generate, update, express.js, parser-cache, or any application with similar conventions.

Usage

1var parser = require('parser-front-matter');

API

.parse

Parse front matter from the given string or the contents in the given file and callback next(err, file).

If an object is passed, either file.contents or file.content may be used (for gulp and assemble compatibility).

Params

• file {String|Object}: The object or string to parse.
• options {Object|Function}: or next callback function. Options are passed to gray-matter.
• next {Function}: callback function.

Example

1// pass a string
2parser.parse('---\ntitle: foo\n---\nbar', function (err, file) {
3  //=> {content: 'bar', data: {title: 'foo'}}
4});
5
6// or an object
7var file = {contents: new Buffer('---\ntitle: foo\nbar')};
8parser.parse(file, function(err, res) {
9  //=> {content: 'bar', data: {title: 'foo'}}
10});

.parseSync

Parse front matter from the given string or the contents in the given file. If an object is passed, either file.contents or file.content may be used (for gulp and assemble compatibility).

Params

• file {String|Object}: The object or string to parse.
• options {Object}: passed to gray-matter.

Example

1// pass a string
2var res = parser.parseSync('---\ntitle: foo\n---\nbar');
3
4// or an object
5var file = {contents: new Buffer('---\ntitle: foo\nbar')};
6var res = parser.parseSync(file);
7//=> {content: 'bar', data: {title: 'foo'}}

file object

Returned file objects have the following properties (no other properties are modified on the given file):

• data: data from parsed front matter
• content: the content string, excluding front-matter (assemble compatibility)
• contents: the content string as a buffer, excluding front-matter
• orig: the original content string with front-matter included
