# DEPRECATION NOTICE



I'll archive the repo by the end of August 2021.



The main reason is [Hugo pipes](https://gohugo.io/hugo-pipes/) are built-in and pretty much cover what Hugulp does.



I think the only part missing is image optimization, but I think you can build a pipe to do it.



The other reason is it badly needs an update to gulp 4 and although it doesn't seem like that hard a task, I don't have the appetite to do it.



# hugulp 2



## v2 Breaking changes



If you're using hugulp v1, please take note of the following changes:



* hugo is no longer invoked by hugulp



  use hugo as per its docs, then invoke hugulp build



* put your assets in the static folder



  for example, static/styles, static/images, static/scripts



* themes are supported out of the box



_Note: If you need sass/less/js pre-processing, read v2 docs below_



## Description



`hugulp` is a tool to optimize the assets of a [Hugo](https://gohugo.io) website.



The main idea is to recreate the famous [Ruby on Rails Asset Pipeline](http://guides.rubyonrails.org/asset_pipeline.html), which minifies, concatenates and fingerprints the assets used in your website.



This leads to less and smaller network requests to your page, improving overall user experience.



Read [this blog post](https://jbrio.net/posts/mobile-friendly-website-2/) and [this article](https://medium.com/@juanbrodriguez/hugulp-a-hugo-gulp-toolchain-94f72ccc3577) for additional context.



_Note: These articles refer to v1_



It's internally driven by [Gulp](https://gulpjs.com).



This project Includes the following tools, tasks and workflows:



* [sass](https://github.com/dlmanning/gulp-sass) (super fast libsass)

* [less](https://github.com/plus3network/gulp-less)

* [autoprefixer](https://github.com/sindresorhus/gulp-autoprefixer)

* [clean-css](https://github.com/scniro/gulp-clean-css)

* [jshint](https://github.com/spalger/gulp-jshint)

* [uglify](https://github.com/terinjokes/gulp-uglify)

* [imagemin](https://github.com/sindresorhus/gulp-imagemin) (only [changed images](https://github.com/sindresorhus/gulp-changed))

* [gulp-rev](https://github.com/sindresorhus/gulp-rev), [gulp-rev-replace](https://github.com/jamesknelson/gulp-rev-replace) (fingerprinting)

* [htmlmin](https://github.com/jonschlinkert/gulp-htmlmin)

* [watch](https://github.com/floatdrop/gulp-watch)



## Installation



[Node](https://nodejs.org) needs to be installed in your system.



Then just



```bash

$ npm install -g hugulp

```



Or you can build and run using [docker](https://www.docker.com):



```bash

# Default docker setup:

$ ./scripts/create-docker-machine-and-run-it



# -- OR --



# Run with custom machine name, specific hugo version, specific node version and run docker in detached mode:

$ ./scripts/create-docker-machine-and-run-it -a app-devel -g 0.20.6 -n 6.10.0 -d

```



**Note:** You only run the `./scripts/create-docker-machine-and-run-it` if you want to create a new docker machine. Once the docker machine is created, you have to use docker commands to manage it. Please be familiar with docker in this regard.



## Getting Started



The most common usage scenario would be:



```bash

$ hugo new site yoursite

$ cd yoursite

$ hugulp init

# create content

# add images (static/images), css (static/styles) and javascript (static/scripts)

$ hugo server -D # for development

# development is done, ready to publish

$ rm -rf public # clean up public folder, it will be re-generated by hugo

$ hugo # for release/production/deployment

$ hugulp build # optimize the site by running the asset pipeline

```



Another scenario would be to include sass/less pre-processing:



```bash

$ hugo new site yoursite

$ cd yoursite

$ hugulp init

# create content

# add images (static/images), and javascript (static/scripts)

# add sass/less (assets/styles)

$ hugo server -D # for development

$ hugulp watch # to convert sass/less (assets/styles) into css (static/styles)

# development is done, ready to publish

$ rm -rf public # clean up public folder, it will be re-generated by hugo

$ hugo # for release/production/deployment

$ hugulp build # optimize the site by running the asset pipeline

```



In both cases, you could chain the last 3 commands:



```bash

$ rm -rf public && hugo && hugulp build

```



`hugulp` requires a configuration file (`.hugulprc`), which is created by the `hugulp init` command (you can create the file manually if you want).



This is the default `.hugulprc`:



```json

{

  "version": 2,

  "pipeline": ["images", "styles", "scripts", "fingerprint", "html"],

  "path": {

    "styles": "styles",

    "images": "images",

    "scripts": "scripts"

  },

  "watch": {

    "source": "assets",

    "target": "static"

  },

  "build": {

    "source": "public",

    "target": "public"

  },

  "autoprefixer": {

    "browsers": ["last 2 versions"]

  },

  "cleancss": {

    "advanced": false

  },

  "htmlmin": {

    "collapseWhitespace": true

  },

  "gifsicle": { "interlaced": true },

  "jpegtran": { "progressive": true },

  "optipng": { "optimizationLevel": 5 },

  "svgo": {

    "plugins": [{ "removeViewBox": true }, { "cleanupIDs": false }]

  }

}

```



You can easily customize `hugulp`'s behavior, by modifying this configuration file, as described below.



## Available Commands



### hugulp watch



`hugulp` will assist you if you're using sass/less (and javascript), which require pre-processing.



It will watch for changes to styles or script files, process them and write them to hugo's static folder, according to the following table



| In Folder      |      Looks for       | Operation                              | Written to     |

| -------------- | :------------------: | -------------------------------------- | -------------- |

| assets/styles  | s[a\|c]ss, less, css | Convert sass/less to css               | static/styles  |

| assets/scripts |          js          | Lint javascript code (_soon babelify_) | static/scripts |



_Note: It searches the folders recursively_



The table above applies to `hugulp` run with a default `.hugulprc`.



You can customize the folder names: `resources` instead of `assets`, `js` instead of `scripts` and so on.



This is described in the `.hugulprc` section below.



### hugulp build



It optimizes the site that hugo built, by running the asset pipeline as defined in `.hugulprc` (field _pipeline_).



Additionally, files are not watched for changes



### hugulp version



Display installed version.



### hugulp init



Create a default `.hugulprc`.



## Configuration



By editing the `.hugulprc` configuration file, you can customize almost anything about `hugulp`.



Description of each field follows:



### pipeline



Defines which tasks of the asset pipeline will be executed (`hugulp build` command)



Type: array 


Default:



```json

"pipeline": ["images", "styles", "scripts", "fingerprint", "html"]

```



| Task        | Description                                                        |

| ----------- | ------------------------------------------------------------------ |

| images      | minify images with `imagemin`                                      |

| styles      | pre-process `sass`/`less`/css, then `clean-css`                    |

| scripts     | `jshint`, then `uglify`                                            |

| fingerprint | fingerprint with `rev`, then replace references with `rev-replace` |

| html        | minify html with `htmlmin`                                         |



Let's say you don't want to fingerprint the assets. Just set _pipeline_ to



```json

"pipeline": ["images", "styles", "scripts", "html"]

```



By removing the _fingerprint_ task, it will not be executed.



Note that tasks are executed sequentially.



### path



Defines the name of the folders where your assets are located/will be transferred to.



Type: object 


Default:



```json

"path": {

  "styles": "styles",

  "images": "images",

  "scripts": "scripts"

}

```



So if you prefer your styles folder to be called css, and scripts to be called js, you would change it to:



```json

"path": {

  "styles": "css",

  "images": "images",

  "scripts": "js"

}

```



### watch



Define which folders to watch for changes, for the `hugulp watch` command.



Type: object 


Default:



```json

"watch": {

  "source": "assets",

  "target": "static"

}

```



This field works together with the path field.



With a default `.hugulprc`, it will watch `assets/styles` and `assets/scripts` (recursively).



If you customized `path` as per above, it will watch `assets/css` and `assets/js`.



If you additionally want the `assets` folder to be called `resources`, change _source_ to `resources`



```json

"watch": {

  "source": "resources",

  "target": "static"

}

```



then it will watch `resources/css` and `resources/js`



Finally, the changes will be written to the well-known hugo static folder.



With a default `.hugulprc`, files will be written to `static/styles` and `static/scripts`.



### build



Defines the folders referenced during the `hugulp build` command



Type: object 


Default:



```json

"build": {

  "source": "public",

  "target": "public"

}

```



This should generally be left unchanged.



`hugo` will output to the public folder by default, so `hugulp build` will process the files in-place.



### autoprefixer



Options for `autoprefixer`. Check [gulp-autoprefixer](https://github.com/sindresorhus/gulp-autoprefixer) for documentation.



Task: `styles`



Type: object


Default:



```json

"autoprefixer": {

  "browsers": ["last 2 versions"]

}

```



### cleancss



Options for `clean-css`. Check [gulp-clean-css](https://github.com/scniro/gulp-clean-css) for documentation.



Task: `styles`



Default:



```json

"cleancss": {

  "advanced": false

}

```



### htmlmin



Options for `htmlmin`. Check [gulp-htmlmin](https://github.com/jonschlinkert/gulp-htmlmin) for documentation.



Task: `html`



Default:



```json

"htmlmin": {

  "collapsedWhitespace": true

}

```



### gifsicle



Options for `gifsicle`. Check [gulp-imagemin](https://github.com/sindresorhus/gulp-imagemin) for documentation.



Task: `images`



Default:



```json

"gifsicle": {

  "interlaced": true

}

```



### jpegtran



Options for `jpegtran`. Check [gulp-imagemin](https://github.com/sindresorhus/gulp-imagemin) for documentation.



Task: `images`



Default:



```json

"jpegtran": {

  "progressive": true

}

```



### optipng



Options for `optipng`. Check [gulp-imagemin](https://github.com/sindresorhus/gulp-imagemin) for documentation.



Task: `images`



Default:



```json

"optipng": {

  "optimizationLevel": 5

}

```



### svgo



Options for `svgo`. Check [gulp-imagemin](https://github.com/sindresorhus/gulp-imagemin) for documentation.



Task: `images`



Default:



```json

"svgo": {

  "plugins": [{ "removeViewBox": true }, { "cleanupIDs": false }]

}

```



## How to update



Whenever a new `hugulp` version becomes available, you can update it by running



```bash

$ npm install -g hugulp

```
