layouts
Wraps templates with layouts. Layouts can use other layouts and be nested to any depth. This can be used 100% standalone to wrap any kind of file with banners, headers or footer content. Use for markdown, HTML, handlebars views, lo-dash templates, etc. Layouts can also be vinyl files.
Please consider following this project's author, Brian Woodward, and consider starring the project to show your :heart: and support.
Install
Install with npm:
$ npm install --save layouts
Usage
const renderLayouts = require('layouts');
renderLayouts(file, layoutCollection, options);
file
- a file object (or vinyl file) with a file.contents
property that must be a bufferlayoutCollection
- an object of file objects to use as layoutsoptions
- see available options
Heads up!
This library does not clone the file object. If you want to prevent file.contents
from being mutated (after rendering layouts), clone the file first before passing it to this library.
Example
const renderLayouts = require('layouts');
const file = {
contents: Buffer.from('<div>Wrap me with a layout!!!</div>'),
layout: 'one'
};
const layoutCollection = {
one: { contents: Buffer.from('one before\n{% body %}\none after'), layout: 'two' },
two: { contents: Buffer.from('two before\n{% body %}\ntwo after') }
};
const res = renderLayouts(file, layoutCollection);
console.log(res.contents.toString());
Options
options.disableHistory
Type: boolean
Default: undefined
By default, layouts are prevented from being applied multiple times to the same string. Disable this by setting disableHistory
to true.
Example
layouts(file, layoutCollection, { disableHistory: true });
options.layoutDelims
Custom delimiters to use for injecting contents into layouts.
Type: regex
Default: /{% (body) %}/g
options.preserveWhitespace
Preserve leading whitespace when injecting a string into a layout.
Type: boolean
Default: undefined
History
1.0.0
Breaking changes
- renames
layoutHistory
to layoutStack
- layouts in
layoutStack
are now the actual layout object, instead of the layout name
Added
- Adds support for a function as the last argument. If passed, the function is called on the file and each layout with this signature:
fn(file, layout)
.
0.13.0
Breaking changes
- The main
layouts()
function now expects a file
object as the first argument. This can be an object with path
, layout
and contents
properties, or a valid vinyl file. See the API docs for more details.
0.12.0
Breaking changes
- change
options.tag
to options.contentTag
Housekeeping
- update tests to use
assert
instead of should
0.11.0
- All view objects must now have a
path
property, following vinyl conventions.
