Please take a look at the getting started section for basic setup guide.

The Unglue client is responsible for reading the .unglue files which defines the config, find all associated files (css, js) collect the values and transmit those informatiosn to the Server. The response from the server will then be stored in the designated files.


The client client binary must be installed trough composer.

composer require --dev unglue/client

Afterwards the bin file is available in vendor/bin/unglue.

Config file

The .unglue files are the place where the magic happens. Depending on the file name (e.g main.unglue) this is what your output will look like (e.g. main.css and/or main.js). The unglue files must be stored as valid json, and currently contains the following sections:

  • css: An array with valid paths to scss files.
  • js: An array with valid paths to javascript files which should be compiled.
  • svg: An array with paths to svg which should be collected and returned as single svg sprite file.
  • options: Options for the compiling request, see the configuration option section for more details.

And example of an anglue file which will read a main.scss file and collect and compile a few javascript files. Also options like compress (uglify) and maps (source maps) are enabled:

    "css": [
    "js": [
    "options": {
        "compress" : true,
        "maps" : true


In order to generate an svg sprite from several svg sources you can use the svg key inside an unglue file:

    "svg": [

This will create an svg file with the same name as the unglue file has.


    "options": {
        "compress" : true,
        "maps" : true
name type description
compress boolean compress css and js
maps boolean generate maps file for css and js

Change Server

Run the watch or compile commands with argument --server=localhost:3000 in order to connect to anyother server. By default you will connect to the cloud compile server of the unglue project.


Arguments can be added to the commands like --server=localhost:3000 or --timeout=20000:

options description watch compile
--server Define a server to connect
--timeout The timeout in miliseconds between a next watch iteration is triggered. Default is 500000
--reindex After the certain amount of watch iterations the unglue client will reindex new files and check for changes in unglue files. Default is 10 (this means every $timeout * $reindex new indexing is done). If set to 0 the reindex behavior is turned off.
--symlinks Whether symlinks should be followed or not to find unglue and scss files (since 1.4)
--exclude Exclude certain folders to find unglue files, default is vendor/,public_html/assets/ (since 1.1)
