markdown/muport-core-js master
markdown/ethr-did develop
markdown/ethr-did-resolver develop
markdown/ethr-did-registry develop

Get started

Check out the repository and from the root of the project:

  1. npm install.
  2. Edit .gitmodules or add new markdown sources with git submodule add.
  3. Edit gulp/copy.js to copy the desired folders to the /content/public folder
  4. npm run setup
  5. npm run dev


  1. Node v10.1.0
  2. NPM v6.0.1

For deployment

  1. Ngrok (for deployment steps)
  2. AWS credentials to push to the appropriate buckets and invalidate CloudFront cache.
  3. Permissions to push to the master branch.

There is a known issue with Node 10 and gulp


rm -rf node_modules/
rm -rf package-lock.json
sudo npm install --unsafe-perm=true


npm run setup

Run this command if you need to reset your workspace or have just cloned the repository for the first time.

Running this command will do the following:

  1. Installs custom plugins contained in the /plugins folder.
  2. Fetches markdown from remotes configured in .gitmodules.
  3. Cleans the /public folder.
  4. Copies cloned content from /markdown to /content/public

npm run copy:markdown

Periodically it will be necessary to apply updates to the documentation markdown contained within the /repos folder. When a local development instance of the site is running, this changes can be applied by running this command to copy the files from /repos to /content/public.

npm run watch:markdown

This command watches the /markdown folder for updates. Any time an update happens it will run copy:markdown. This enables live updates of markdown in development mode when combined with npm run dev.

npm run update:markdown

To pull in documentation updates from the remote repositories, run this command. It does the following:

  1. Fetches markdown from remotes configured in .gitmodules.
  2. Copies cloned content from /markdown to /content/public

npm run dev

Run this command to build and run a local instance of the developer docs at http://localhost:8000. GraphQL queries can be inspected at http://localhost:8000/___graphql. npm run update:markdown can be run while the site is running locally to apply apply updates from local or remote markdown sources.

npm run serve

This will serve the contents of the public folder using NGROK, so the site can be reviewed without deployment. The site must be built using npm run build prior to attempting to run the serve command.

npm run deploy:production

This will build and deploy the website using Github pages for the production build.

npm run deploy:development

This will build the site and deploy it to for review

npm run deploy:legacy

This will build the site and deploy it to our legacy S3 bucket to maintain a version snapshot of the developer site.

npm run generate-readme

Should be run any time the is updated. This gets run automatically any time the site is built.


  • The git configuration for the project should use SSH vs. HTTPS to avoid having to type passwords when checking out the individual markdown repositories.

Project configuration(s):

  1. Site /data/SiteConfig.js
  2. Styling /src/layouts/theme.js
  3. Content /repos.json
  4. GatsbyJS configuration gatsby-config.js

1. Site configuration

The SiteConfig.js file contains properties that are used by the site generator at compile time. It contains configuration options like setting a path-prefix, the site name, logo images, etc.

At a minimum the siteUrl and pathPrefix should be set.

Example SiteConfig and each properties explanation:

module.exports = {
  siteTitle: "Simple and secure login for your Ethereum app",           // Site title.
  siteTitleAlt: "Uport ID makes blockchain easy on desktop and mobile", // Alternative site title for SEO.
  siteLogo: "/logos/uport-logo-purple@3x.png",                          // Logo used for SEO and manifest.
  siteUrl: "",                                  // Domain of your website without pathPrefix.
  pathPrefix: "/",                                                      // Prefixes all links. For cases when deployed to
  siteDescription: "Uport ID makes blockchain easy on desktop and mobile", // Website description used for RSS feeds/meta description tag.
  siteRss: "/rss.xml",                                                  // Path to the RSS file.
  googleAnalyticsID: "UA-8xxxxx",                                       // GA tracking ID.
  userName: "uPort",                                                    // Username to display in the author segment.
  userTwitter: "uport_me",                                              // Optionally renders "Follow Me" in the UserInfo segment.
  userLocation: "Universe",                                             // User location to display in the author segment.
  userAvatar: "", // User avatar to display in the author segment.
  userDescription: "Your ID.  For you.",                                // User description to display in the author segment.
  segmentProdKey: "",                                                   //Segment key for prod
  segmentDevKey: "",                                                    //Segment key for dev
  copyright: "Copyright © 2018",                                        // Copyright string for the footer of the website and RSS feed.
  themeColor: "#5c50ca",                                                // Used for setting manifest and progress theme colors.
  backgroundColor: "#e0e0e0",                                           // Used for setting manifest background color.

2. Styling configuration

The theme.js file contains a couple attributes that are used to toggle CSS properties. For convenience the theme styles are included, but others can be added as needed.

const theme = {
  // named colors:
  brand: '#5c50ca',
  accent: '#ADD2EB',
  accentDark: "#35495E",
  lightGrey: '#F6F6F6',
  darkGrey: '#91a2a3',
  ink: 'black',
  errorRed: '#FF6666',
  codeEditBlue: '#2973b7',
  codeEditGreen: '#42b983',
  themedWhite: '#f5f2f0',
  // content width:
  contentWidthLaptop: '850px',
  sitePadding: "25px",


export default theme;


  1. Code highlighting is done with PrismJS. Prism Themes have been installed, and is utilized in /src/layouts/index.jsx
  2. Our CSS is imported from weblow.
  3. The only CSS file that should be modified directly is src/layours/css/index.css. Use this to make changes to the defaults that are imported.

3. Content configuration

Our content is stored in remote repositories which are configured in a file called .gitmodules. We use git submodules to keep content in sync.

The uPort site generator assumes convention over configuration. For the submodule markdown to be included into the documentation site, consider the following:

Header guidelines
  1. Be consistent with header hierarchy. Don't skip sizes.
  2. Only use H1 headers for something intended to be a title (keep it short)
  3. Both H1 and H2 headers are used for site navigation and category indexing. Keep them shorter and contextual.
  4. Always leave 1 space after a hash tag.
  5. Avoid periods, special characters and punctuation in any H1 or H2 headlines.
  6. For topics that are nested use a smaller-header hierarchy to represent a deeper nesting.
  7. Avoid too-many H2 headers in a single document. Use better information architecture.
Front matter conventions

The front matter is the way to inform the site generator how to handle each file. Each markdown document intended to be a source for the developer site should have a minimum set of front matter attributes, written in YAML.

Place a modified version of the following directly at the top of each markdown file with no preceding spaces.

title: "Attesting Credentials"
index: 1
category: "guides"
type: "content"

The following keys are required:

  1. title
  2. category
  3. type

The following are optional:

  1. index
  2. announcement
Front matter (title)

Used for the page title as well as navigation links. They should be kept short and be the same as H1 headings in most cases. There may be times when these should differ, for example, having a link to display by a different name than represented by the heading.

Front matter (index)

Think of this as the display order for the content; it is used to sort each category and control the ordering of navigation links. Note: if the frontmatter does not contain an index, the site-generator will assume it is sub-content that does not belong in table of contents or navigation menu.

Front matter (category)

Categories are used to aggregate markdown for header menus and contextual relevancy. The main categories are guides, overview, and reference but new categories may be added at any time. When a new category is added that follows the proper conventions it will be included in the header navigation menu. The previously mentioned categories default to the first three navigation sections in the header. New categories will added onto the end and displayed last.

Front matter (type)

The type is important for publishing. If the type is not "content" it will not be published or displayed.

Front matter (announcement)

This is used to broadcast a message across all pages on the site. Use sparingly.

Repository guidelines

Please use this general guidance:

  1. Keep the readme short and sweet and detail how to contribute / support.
  2. Put detailed content, like implementation details in the /docs folder.
  3. Docs folders can have: guides, tutorials, sdk/api reference documentation.
  4. Follow the documentation guidelines on the docs repo.

One suggestion I have is to use a similar nomenclature as this repo for the /docs folder.


  • /docs
    • /guides
    • /reference
    • /overview
    • (can use this if you want Oloron to have it’s own index. page, otherwise we default to the markdown-frontmatter’s first “guide” at index 0)
  • (add install information, support and contribution information, NPM release badges, etc. )

4. GatsbyJS Configuration

The gatsby-config.js file bootstraps all the plugins that are utilized by GatsbyJS to build the site. Most of the options here are configured through SiteConfig.js and utilized within `gatsby-config.js`` at runtime.


There is a /plugins folder that contains custom code. At this time the following custom plugins are:

  1. gatsby-remark-copy-linked-files
  2. gatsby-remark-catch-relative-markdown-links

This is a plugin provided by GatsbyJS. It's purpose is to iterate over all markdown documents and copy any files/images that are linked to the /public folder. It then re-writes the links within the markdown to point to the new file location. We have extended it to ignore relative links to markdown files otherwise the relative links would be broken.

It is configured within gatsby-config.js and now accepts a new option ignoreRelativeMarkdownLinks

            resolve: "gatsby-remark-copy-linked-files",
            options: {
              ignoreRelativeMarkdownLinks: true

This is a custom plugin that is used to re-write the relative links to markdown documents. It detects if a link is a relative link and is a markdown document then updates the link to point to the new location within the /public folder.


There are a few things to take note of, or would be good to know while working with this repository.


This is the brain of the site. It contains two functions, createPages and onCreateNode.

The former uses the output of onCreateNode to physically create the pages.

The later is used to apply updates to the page frontmatter that are used by GraphQL queries to build the site. In this instance it sets the slug for each page. Slugs are eventually used to create the static content at the location that the slug specifies during createPages.


This contains configuration for several plugins used by gatsby. Without this configuration gatsby-node.js will be unable to find the files and operate on them.


We deploy the github pages from the master branch. That means we work off the develop branch and tag releases.

ngrok is required

The deployment steps for uPort are:

Always run deploy:production from a release tag. Never from the develop branch

  1. Check out the latest release tag.
  2. Run npm run build. This will build a production-ready version of the site.
  3. Run npm run serve to serve the site on a public DNS (ngrok) to test with.
  4. Run npm run deploy:development to deploy the site to
  5. Once ready, run npm run deploy:production to deploy the site to
  6. Go to and update the custom domain to reflect our documentation home (

Manual deployment can be done. Simply build the site and copy the output to its destination.

  1. To build the site execute npm run build.
  2. Copy or push the contents of the /public folder to its intended destination or gh-pages branch

Depending on the deployment destination (S3, Netflify, **), this command can be modified.

You can’t perform that action at this time.
