# Jekyll lean startup template

A template for small teams to deploy landing pages and small websites cheap and fast, engage non-technical contributors, and architect information over time.

## Introduction

### Intention

The developer experience is most of the time terrible with content management systems that ship WYSIWYG editors, and learning HTML and managing metadata is too much for the vast majority of non-technical users. **I aim for the sweet spot where efficient contribution is possible both for developers and non-technical users**.

This repository aims at making it easier to use Jekyll to:

- **Publish websites** or at least landing pages, not blogs.
- **Get contributions from non-technical users**, purely with online code editors.
- **Build upon convention** rather than configuration.
- **Display page metadata**.

It regroups the setup and best practices I have identified. While reusable as such, it is perhaps better to think of it as a library of examples than as a template.

### Context

[Jekyll](https://jekyllrb.com/) is a static website generator.

> This means it transforms pieces of content in Markdown or HTML into full HTML files that can be displayed in web browsers.

It is flexible and easy to use. Other static website generators exist. However, one of the main benefits of Jekyll is that it can be run and hosted for free directly by code hosting platforms such as [GitHub](https://pages.github.com) or [GitLab](https://docs.gitlab.com/ee/user/project/pages/) through their Pages feature, and you can always switch to your own server at any time.

> This means your website can be made available on the internet at no cost.

Jekyll claims to be “blog-aware”. It is indeed, supporting notions such as posts, publishing dates and authors out of the box. More than “aware”, though, the default boilerplate and some of the documentation will guide you towards blog posts.

Jekyll can do much more than that and, over the years, I have come to build and reuse a set of practices and presets that support my main use case: building and deploying landing pages cheap and fast (under half a day) that enable non-technical users to contribute content through online text editors, and maintain an ability to scale to an entire website with full quality control.

### Examples

This approach has enabled me to build products such as:

- [beta.gouv.fr](https://beta.gouv.fr), the website of the French government public digital services incubator, which uses Jekyll both as CMS and HR system and has [over 370 contributors](https://github.com/betagouv/beta.gouv.fr/) of all sorts.
- [disinfo.quaidorsay.fr](https://disinfo.quaidorsay.fr), a resource supporting actors countering information manipulation (aka “fake news”), which uses Jekyll for a [multilingual](https://github.com/ambanum/disinfo.quaidorsay.fr/tree/master/_pages), [collaborative encyclopedia](https://github.com/ambanum/disinfo.quaidorsay.fr/tree/master/_pages/en/encyclopedia) of tools and practices.
- [pariscall.international](https://pariscall.international), the public website for the Paris Call for Trust and Security in Cyberspace, which uses Jekyll to maintain a [list of signatories](https://github.com/ambanum/pariscall.international/tree/master/_supporters) and relies on an additional [backend](https://github.com/ambanum/pariscall.international-backend) to [create files](https://github.com/ambanum/pariscall.international/commits?author=AmbNum-Bot) from survey answers, making it easy for anyone to add files and for non-technical maintainers to update the data over time.


## Features

### Production & development versions synchronisation

It is standard practice to ensure that development and production environments are in sync, in order to ensure bugs can be caught before production, or at least reproduced in development. Most of the time, this is achieved by locking down versions in development so that production updates accordingly.

However, when relying on hosting providers such as GitHub Pages, the host manages production versions. In this case, the only way to ensure both environments are in sync is to… enforce production versions in dev!

The `Gemfile` in this repository is dynamic and fetches GitHub’s [production versions](https://pages.github.com/versions.json). A fallback mechanism supports offline work and assumes local versions are correct —you won’t be pushing work if you’re offline anyway 🙂

> [Credit](https://github.com/betagouv/beta.gouv.fr/commits/master/Gemfile) goes to @MaukoQuiroga for most of the dynamic Gemfile code.

The Ruby version itself is locked with the `.ruby-version` file, and `bundler` will complain if it does not match the production version. I suggest to [install `rbenv`](https://github.com/rbenv/rbenv#installation) to manage and automatically switch the Ruby version.

> The alternative to rbenv is RVM. If you have it already installed on your system, or you prefer to use it for any reason, there is no need to switch to rbenv.

In CI, the `.circleci/config.yml` in this repository builds using the same versions and options as GitHub Pages does, such as “safe mode” which disables most plugins, and enforces additional checks such as HTML spec compliance.

> The Jekyll documentation provides a [template for CircleCI](https://jekyllrb.com/docs/continuous-integration/circleci/), but it assumes a deployment to Amazon S3 where you control production versions.


### Maintenance mode

If you need to keep building the website without technical interventions, such as for example if some collaborators edit content without having the ability to change the code and there is no more technical support available long term, a failing CI can become an issue.

In that case, you could disable CI entirely. However, this means you would lose content validation, which would still bring value to non-tech collaborators. Hence, the recommended step is to disable version check in CI, leaving it to technical collaborators to ensure synchronisation when they intervene on the code.

In order to lock down dependencies and maximise the time without which a technical intervention is necessary, you should lock down all dependencies versions, remove runtime version checks in CI, and switch to building in CI rather than relying on GitHub Pages updates, as these updates can be incompatible with your specific developments. The specific way of locking down dependencies is all documented in comments starting with “Maintenance mode instructions”.

### Advanced features discoverability

Some of the lesser-known yet very powerful features of Jekyll are [collections](https://jekyllrb.com/docs/step-by-step/09-collections/) and [includes](https://jekyllrb.com/docs/step-by-step/05-includes/). The default Jekyll template, by staying minimal, does not help with making those discoverable.

This is why this template showcases and prefills the `_includes` folder and defines a collection in `_config.yml` with both an explicit output and default values that demonstrate the power of collections.


### Information architecture through collections

Jekyll is most often used in a way where the information architecture (i.e. content hierarchy) reflects the folder hierarchy of content files. While a definitely easier way to get started, this has two major drawbacks:

1. Mixing of content hierarchy and dev setup: at the root of your repository lie both the root page and paths that will be exposed on your website and all the weird dev files such as `Gemfile`. This makes it very confusing for non-technical users.
2. Underuse of the powerful metadata management and styling features that can be derived from assigning each piece of content to a category.

This is why this template suggests to only store content in [collections](https://jekyllrb.com/docs/step-by-step/09-collections/). This will help you think about content hierarchy, make sure all your content is in scoped folders, enable the use of default values for layout and metadata for each folder, and let you teach non-technical contributors that they can change anything they want as long as they work in some given folder (which they can, for example, bookmark in their browser).

The only folder that is exposed directly is `assets`, in which files that should be processed as a pass-through are to be stored.


### Styling

Jekyll does support [themes](http://jekyllthemes.org), so it is tempting to think you can create content and later on make it beautiful. While this can work for well-known forms of content such as blog posts, this is usually not a satisfying approach when you are building custom websites.

If you manage your own styles with Jekyll, you will manipulate layouts and CSS. Since the content is static, rather than including stylesheets on a page-by-page basis, many websites end up including all their stylesheets on all pages (or creating a single one with Sass), decreasing web performance.

This is why this template supports three ways to ease category-by-category styling:

1. For minor adjustments, a CSS class name is added on the `body` of each page with the name of the current layout as soon as it is not `default`. For example, if you define `layout: tree` on a page, then its body will have class `.layout-tree` so that you can easily target elements within.
2. For major variations, a stylesheet is automatically loaded for each layout. For example, if you set `layout: tree` on a page, then it will load the stylesheet at `assets/css/tree.css`. If you don’t need this feature, the best is to simply remove the corresponding lines in the default layout.
3. The `additional_css` front-matter property loads all stylesheets listed there, so that any page or collection can load arbitrary files.

> I personally prefer to use standard CSS over Sass, but that choice is obviously up to you and Jekyll does [support Sass / SCSS as preprocessors](https://jekyllrb.com/docs/assets/#sassscss).


### Social cards

Most Jekyll themes don’t provide the [meta tags for “social cards”](https://gist.github.com/MattiSG/fc7f65ad16fb8968e0f84b756efd9383) that will enable rich content preview on major social media.

The `_includes/metadata.html` in this repository ships the minimal amount of code to enable rich preview on Facebook, Twitter, LinkedIn and any other [OpenGraph](https://ogp.me)-compatible scraper.


### Custom builds and non-“safe” plugins on GitHub Pages

GitHub Pages provides free and fast deployment, but relying on GitHub-provided Jekyll compilation adds limitations to how much you can customise the process.

The `_scripts/deploy.sh` script in this repository, combined with the pre-filled CI config file, enables CI compilation and deployment of your Jekyll website as a pure HTML dump on GitHub Pages, allowing you to benefit from GitHub’s hosting without relying on their more constrained Jekyll engine.


## Tips

### Compress assets

Since your files are stored in Git, and they will be exposed directly, it is a very good idea for the performance of both your public website and production workflow to compress assets _before_ they are committed to the repository. In particular, I strongly recommend using [ImageOptim](https://imageoptim.com/) or an equivalent service to compress images before committing them.


### Provide magic links to non-technical contributors

#### To create new files

Creating a new file is significantly harder than editing existing ones in the online editor interface. In order to make it easier for non-technical users to create new content, we can create special links that embed a template file, by using query string variables.

For example, the GitHub online editor will use `filename` and `value` as URL-encoded values for the file name and file content, so we can craft URLs that will pre-fill a new file, complete with YAML front-matter:

```
https://github.com/${username}/${repo_name}/new/${branch}/${containing_folder_path}?filename=${new_file_name_with_extension}&value=${url_encoded_template}
```

I usually store these links in the `CONTRIBUTING` file.


#### Add direct edit links on each page

This will ease the contribution of both non-technical users, who can navigate the published website rather than the file hierarchy, and of external contributors.

There, the link is much easier to craft by relying on Jekyll-provided variables:

```
https://github.com/{{ site.repository }}/edit/${target_branch}/{{ page.path }}
```

### Use official documentation

- [Jekyll documentation](http://jekyllrb.com/docs/).
- [Jekyll cheat sheet](https://devhints.io/jekyll).
- [Liquid language documentation](https://shopify.github.io/liquid/).


## Adapting this template

- Edit the `_config.yml` to ensure the metadata matches your setup.
- Replace `logo.png` with your own.
- Start the server with the following options: `bundle exec jekyll serve --watch --safe --strict_front_matter`

> - `watch` improves your developer experience: the server will reload automatically when it detects changes to files (except the config file, you’ll get bitten by that at some point).
> - `safe` mirrors GitHub Pages' setup.
> - `strict_front_matter` allows to catch errors early.
>
> While the server will systematically suggest you start it with the `--incremental` option, I recommend to only use this option as an opt-in, when you are iterating quickly over a specific set of pages in a large website. When designing, this is a recipe for getting inconsistent pages where some have updated their links and included assets and others have not, leading to lots of frustration.

### Change the menu

In order to avoid mixing content files with config & dev files, pages are never created at the root: they all get written in collections. In order to add a page to the menu, you can simply add it to `_toplevel`, as long as you set its URL with `permalink`. Prefix their filename with the index at which you'd like them to appear in the menu. The first one (by convention, index `0`) will appear on the left handside of the menu, along with your website logo.


### Publish to GitHub Pages

- Create a repository on GitHub.
- Push your content to it.
- Activate GitHub Pages in the settings.


### Set up Continuous Integration

If you use [CircleCI](https://circleci.com), just log in with GitHub and activate builds for your repository. They offer a free plan for open-source.
