guh

npm install -g guh
guh new

# cd into your new project and 'npm install', then 'guh build'
# use 'npm start' to run the app!

A template project and generator for full-stack TypeScript and Sass (SCSS) projects.

guh has the following goals:

• Flexible configuration
• Intuitive organization
• Isolated builds
• Automated deployments

These goals are accomplished with the following technologies:

• TypeScript
• Browserify
• Sass (libsass)
• PostCSS
• Gulp
• Docker (production)

Sass compiled via guh has globbing and single-import capability via PostCSS plugins.

See CHANGES for a complete changelog.

Requirements

• node >=5.0

Generator CLI

Run guh new (like GNU) to generate a new guh-enabled project. A wizard will guide you through your setup.

Upgrading

Upgrading the guh-core package should be safe within SemVer bounds. Configurations will stay valid across minor version upgrades, but are not guaranteed across major version changes.

Usage

The build system can be run in its default configuration with guh build (or gulp). This loads the default preset defined in the configuration.

Flags can be set with the following syntax:

• --flag: enable
• --flag=yes, --flag=true: enable
• --flag=no, --flag=false: disable

Flags

flag	default	function
watch	no	Watch the filesystem for changes
sourcemaps	yes	Build sourcemaps for client code
minify	no	Minify client code
notify	no	Notify on build completion
browsersync	no	Run client via Browsersync
once	no	Turns off Browserync and file watching if set.
dry	no	Turns off output to the filesystem.

Default values are used if the configuration does not specify a value and value was given on the CLI.

Parameters

parameter	function
--out=PATH	Outputs result into PATH
--preset=PRESET	Sets build preset to PRESET
--only=MODULE[,MODULE2,...]	Build only these modules
--except=MODULE[,MODULE2,...]	Don't build these modules
--gray=MODULE[,MODULE2,...]	Build these modules even if disabled

Presets

Presets set default values for many of these flags and parameters.

Debug

key	value
out	./debug
watch	yes
sourcemaps	yes
minify	no
browsersync	yes

Production

key	value
out	./production
watch	no
sourcemaps	no
minify	yes
browsersync	yes

The default production preset also adds an extra pipeline, copying package.json and Dockerfile to the build directory.

Examples

To build a production build:

guh build --preset=production

To build just stylesheets once in debug mode:

guh build --watch=no --only=stylesheets

To build a debug build without sourcemaps, but with minification to ./derp, try

guh build --sourcemaps=no --minify --out=derp

Files

In debug mode (the default), the output is contained in debug. In production mode, it can be found in production.

Configuration

The primary configuration is located inside build.conf.js. guh will also load build.user.conf.js if it exists, which will take precedence over the primary configuration.

It's recommended that the user config file stays out of version control. It should be based on the following code to patch the primary config:

"use strict";

let conf = require("./build.conf");

// modify conf

module.exports = conf;

Top-Level Configuration

The configuration object has a number of fields that affect compilation globally.

key	value
browsersync	A configuration object passed directly to Browsersync. Omit the object to turn off Browsersync.
preset	The default preset name to use.
presets	A hashmap of defined presets.
pipelines	The list of pipelines to apply when building.

Pipelines

All pipelines are plain JS objects with some specific keys.

Every pipeline may specify these keys:

key	value
type	(required) The type of pipeline to use.
id	An optional unique ID for this pipeline. Duplicates are removed.
tags	A list of tags to group this pipeline with others.
name	A friendly name for the pipeline.
input	(required) This pipeline's input files.
output	This pipeline's output location.
dry	Set to true to disable writing to the filesystem.
disabled	Whether this pipeline is turned off by default. Defaults to false.
config	Extra parameters specific to the pipeline.
callback	A callback to call when a file finishes building. Parameters are (pipeline, filePath, fileContents)
watchPaths	A list of glob-enabled paths to watch for file changes. Works on all pipeline types except browser (guh-core 1.5.0+)

By specifying the same id in two pipelines, values can be overridden in more specific contexts. Defining a pipeline with id of "test" in the base configuration, then defining another pipeline with the same id in a preset will allow the preset to override values.

For example:

{
	presets: {
		production: {
			out: "production",
			pipelines: [
				{
					id: "test",
					disabled: true
				}
			]
		}
	},
	pipelines: [
		{
			id: "test",
			name: "Test the Things!",
			type: "static",
			input: "src",
			output: ""
		}
	]
}

Here, when running in most any preset, the test pipeline will copy some files around. When the production preset is activated, the pipeline will be disabled.

type server

The server pipeline compiles TypeScript files recursively, targeted at server environments.

key	value
extraEntries	Extra entries to pass to the TS compiler, usually typings (.d.ts) files
typingsOutput	The output directory for typings files. Not outputted if omitted.
typingsOutputType	The type of typings to output. "ambient" bundles into a single file, "module" creates typings suitable for bundling in an npm module. Defaults to ambient.
moduleName	The name of the module to export from the typings files. Only used in "ambient" typings output.
moduleEntryPoint	The file marked as the entry point of the module. Only used in "ambient" typings output.

The config parameter is an object with the following keys:

key	value
typescript	Passed directly to TypeScript
partialRebuild	Whether to rebuild only changed files. Faster, but may miss some errors.

type browser

The browser pipeline compiles an entry point TypeScript file and its dependencies into a Browserify bundle.

key	value
extraEntries	Extra entries to pass to the TS compiler, usually typings (.d.ts) files

The config parameter is an object with the following keys:

key	value
typescript	Passed directly to gulp-typescript
browserify	Passed directly to Browserify

type styles

The styles pipeline compiles an entry point Sass file into a single CSS bundle.

The config parameter is an object with the following keys:

key	value
sass	Passed directly to node-sass
sassyImport	Passed directly to postcss-sassy-import
autoprefixer	Passed directly to autoprefixer
stylelint	Passed directly to stylelint

type static

The static pipeline copies files as-is and applies no changes to them.

key	value
rename	Rename the output to this file name. Only works if the input is a single file.
