Interleave is a web construction tool that is designed to help developers build well structured libraries and also web applications.
If you are looking to use the latest version of Interleave, simply run the npm install command as indicated by the nodei.co badge above.
If you have been using Interleave 0.3.x (or possibly 0.4.x) then you should install that particular version:
Interleave was written primarily as a JS alternative to Sprockets which uses a similar comment directed include system. I used interleave for a couple of years to create more structured JS projects.
Personally, I don't use Interleave much at all anymore. Why? Well primarily I found myself spending more time tweaking build tools than actually spending time working on projects. Additionally, once I saw what substack was doing with Browserify from version 2 onwards it became clear to me that for most projects that was a better solution.
This is primarily due to it being used in combination with npm for managing module dependencies. While I felt strongly for a time that browser modules did not belong in NPM, I now believe I was quite wrong and it has proven to be one of the most effective ways of managing software dependencies that I have ever worked with.
All of that said, if Interleave is a good fit for you then you should use it and I'll try to keep it up to date so it continues to work in current node versions.
When using a tool like Interleave it's a good idea to create a
directory (or similar) in which your raw source files will be created.
Personally, I find it works really well to put whichever files you wish
to create a distribution for in this
src/ folder and then place other
sources that will be "rigged" in within subdirectories within the
The following is one example of how a project using Interleave could be structured:
- src/ |- core/ |- a.js |- b.coffee |- mylibrary.js - README.md
The contents of
src/mylibrary.js would look something like:
//= core/a//= core/b.coffee
You could then build your library / app using the following command:
interleave build src/*.js
In fact, as Interleave is built with "convention over configuration" in
mind, you can actually run just
interleave build and Interleave will
infer that you want to build all
.js files within the
interleave command has finished, a
dist/ folder (by default)
will be created and your generated
mylibrary.js file will exist in that
For this and more examples, see the examples folder of this repo.
By default, Interleave will take your input files, rig in specified
includes and spit out the combined result in a
dist folder with a
UMDjs compatible header. If you
specifically want to create separate files for each of the different
module approaches then you can use the
--wrap option to specify either
one module pattern only (e.g.
--wrap=amd) or just tell Interleave that
you want separate files by passing with switch in (
For instance, the following command would take
.js files in the
folder and generate
glob variants in the
interleave build src/*.js --wrap
In the case that you only want specific platform variants (e.g. AMD)
specify a comma-delimited list for the
interleave build src/*.js --wrap glob,amd
If you use CoffeeScript,
Stylus or other precompilers
these are well treated by Interleave (courtesy of
Rigger). Unlike the core
Rigger engine though, Interleave will assume that you want to convert
.styl, etc files into their web consumable
