Numenta Web Platform

Source code, generators, tooling, and content for Numenta websites and platform.

Monorepo

This is a monorepo, managed with Lerna.js. This monorepo contains several child sub-repos (websites, shared components, utils) located in the /packages directory.

Setup

These instructions assume latest Mac OS/X with homebrew package manager installed. Other platforms should come up just as easily.

brew install git node
git clone [email protected]:numenta/numenta-web.git
cd numenta-web/
npm install

You should now be ready to run any of the child Website repos, further details below.

Updating

If you update the child repos and need to re-sync everything back together again, just re-run npm install from the monorepo root.

Linting

To run All Linting checks against JS, CSS, etc:

npm run lint

Testing

To run All Tests (unit, etc):

npm run test

# For older versions of Node.js (< 7, having less harmony)
npm run test --harmony_proxies

Unit

Run only unit tests:

npm run test:unit

Unit tests take and use snapshots in order to perform. Make sure new or updated snapshots are correct before committing! To update these snapshots, try running:

npm run test:unit:update

Run the command below to generate a Unit Test Code Coverage report, which will be saved in your local ./coverage directory.

npm run test:unit:coverage

# open nice coverage report in browser (Mac OS/X)
open ./coverage/lcov-report/index.html

Run unit tests while watching filesystem for changes in realtime (requires 3rd-party Watchman to be installed first):

brew install watchman
npm run test:unit:watch

Hyperlinks

# Test hyperlinks on http://0.0.0.0:8000.
#   You probably have `npm run serve` ready in another terminal window or
#   background job process. Or, you could do `npm run build` and run an http
#   server on the contents of `public/`.
npm run test:links -- http://localhost:8000

Websites

Please change directories to one of the individual website sources, i.e.:

cd packages/numenta.com/

The rest of this section will assume you are in one of the website sub-directories.

Goals

These sites are an attempt at getting back to the roots of the web: reading. Inspired by the classic design of Wikipedia, we hope our sites will be easy to read, helpful for finding information quickly, simple to navigate, and a delight to interact with.

Moving from full statically-generated multi-page websites, to single one-page web applications, is a tricky proposition. Search engine ranking can be affected negatively, as important internal pages and links would disappear. Navigating the user to one of many collapsable sections on a long page can be difficult. Accessible, legacy, and unique browsers cannot usually support the modern technology required for single-page web applications.

To solve these challenges, while still accomplishing our goals, we have built these as hybrid websites. They are both classic statically-generated multi-page websites, and also modern single-page web applications. All clients load the classic static sites initially, and then modern clients will be augmented with the single-page applications. This is accomplished with the magic of "universal" or "isomorphic" javascript, which means that the exact same code is used to generate the static sites on the server, and then is loaded on the clients to continue the applications live.

Gatsby.js is the amazing tool that helps us accomplish all of this.

Stack

Script
- ECMAscript ES6 (Javascript)
  - Node.js engine with npm JS packaging
  - Babel Transpiler down to older cross-browser JS
  - Testing via Jest (on top of Jasmine)
    - This supports our complex Babel, Webpack, and React needs with it's moduleNameMapper stubbing feature.
  - ESLint+Babel code style checking ("linting")
- Gatsby.js static site generator, which wraps:
  - Webpack module loader/bundler
    - Static Generator Plugin webapck plugin
  - React.js reactive view components in JSX format
  - Lunr client-side fulltext site search
Style
- Tachyons Responsive style library, composed via CSS Modules
- Format checking by stylelint
Markup
- Markdown source files, which Gatsby hands to markdown-it
- HTML5 spec
Assets
- React Icon Library
- Images: SVG best, then PNG, etc
- Icons autogenerated by Favicons webpack plugin

Server

Filesystem

The contents of each individual website source directory (i.e. cd packages/numenta.com/) will look like the following:

.                       # Inside `packages/numenta.com/` or similar
├── __tests__/          # Site-specific Tests
├── components/         # Site-specific custom React view Components, etc.
├── config.toml         # Configuration setings for Gatsby static site generator
├── gatsby-browser.js   # Browser-specific code, tied to React Router by Gatsby
├── gatsby-node.js      # Build-time, Node.js, Webpack & Server specific code
├── html.jsx            # Main HTML Document Component
├── package.json        # Project scripts, settings, and `npm` dependency lists
├── pages/              # Webpage Documents and URL Tree Structure
├── public/             # STATIC OUTPUT. Static website generated built files
├── static/             # Static html, styles, assets, etc. Copied after build.
├── utils/              # Local Helpers, utils, client, and misc code
└── wrappers/           # Document-type (.html, .md, etc.) wrapper Components

These websites use shared modules that exist outside of the specific website source directories, located under projects/components and projects/utils. The sites also can have their own custom components/, unique to each site, under their own subdirectory.

The shared Components start out as a base for Numenta.com, where Numenta.org instead uses a few more of it's own custom Components. When making changes to shared Components or Utils, don't forget to run npm run compile to convert down to ES5 first (npm install from root also handles this).

Lifecycle

Gatsby starts Webpack looping over and loading files under pages/. .jsx page code is run as normal. Other file extensions (.md, etc.), which have matching wrappers/ (either Gatsby or custom), are translated accordingly. A few examples of page build paths follow.

Homepage Advanced Section/Pages build path:

http://numenta.com/contact/
- ⇒ (pages/contact/_Section.jsx)
  - ⇒ pages/contact/index.jsx
    - ⇒ (pages/contact/_template.jsx - if exists)
      - ⇒ (pages/_MainSections.jsx)
        
        ⇒ pages/_template.jsx
        
        ⇒ ./html.jsx
        
        ⇒ public/contact/index.html

Regular Page build paths:

http://numenta.com/sitemap/
- ⇒ pages/sitemap/index.jsx
  - ⇒ (pages/sitemap/_template.jsx - if exists)
    - ⇒ pages/_template.jsx
      - ⇒ ./html.jsx
        
        ⇒ public/sitemap/index.html
http://numenta.com/legal/privacy/
- ⇒ pages/legal/privacy.md
  - ⇒ wrappers/md.jsx
    - ⇒ (pages/legal/_template.jsx - if exists)
      - ⇒ pages/_template.jsx
        
        ⇒ ./html.jsx
        
        ⇒ public/legal/privacy/index.html

Client

Lifecycle

Baseline

All browsers and clients will start by loading a classic, simple, statically-generated, multi-page site. This guarantees that all users will receive a decent baseline experience, especially on older, accessible, or unique browsers. This also gives robots and search engine crawlers to have many internal pages to link and index.

Advanced / Targets

After loading the baseline experience, modern clients (listed in the support table below) will then be augmented with an advanced single-page style web application. This lets us simulate a large single main page, with many collapsable sections, much like Wikipedia. This also provides fast "no-refresh" page transitions, a full client-side text search system, etc.

Note: All versions are "Latest Stable" unless otherwise noted.

	Chrome	Firefox	Safari	Edge	IE/11	IE/10	Android
Mac/OSX	✓	✓	✓
iOS			✓
Android	✓						✓
Win/10	✓	✓		✓

Build

Builds should be run from inside each websites individual source directory (cd packages/numenta.com/).

Average build wait times:

Environments	4x 2.8ghz 16gb	2x 2.6ghz 8gb
Dynamic Dev	~10s	~20s
Static (Any)	~6m	~12m

Additional Notes:

Config: Unless otherwise stated below, the config.toml file should have the default empty linkPrefix setting:
```
# config.toml
linkPrefix = ""
```
Disqus Comments: Disqus Comments only work on Production by default, not under Development, Staging, etc. You can test/verify outside Prod by sending an override production Post URL to Disqus via the component, here.

Development

Dynamic

npm run dev
# Visit http://localhost:8000

Additional Notes:

Static Assets: Static assets won't load correctly from static/assets during dynamic dev, but they will be fine later on staging and production after static build. Try the static dev (next section below) if you need the static asset links to work during development.
Specific Local IP: If you need to host via a specific local IP (testing on a VM, etc.), gatsby options can be passed to npm run like this:
```
npm run dev -- --host 192.168.1.112 --port 8765
# Visit http://192.168.1.112:8765
```
Search: To get search working under local dynamic development mode, you first need to build the search index, and then copy the index over to where it will be accessible by the dev webserver:
```
npm run build
cp public/_searchIndex.json pages/.
```

Static

npm run serve
# Visit http://localhost:8000

Integration

Update Gatsby config for GitHub Pages (gh-pages) integration targets. Modify config.toml and set (but DO NOT commit):

# config.toml
linkPrefix = "/numenta-web"

And then run an integration build:

npm run build

Personal

Push build to personal fork origin:gh-pages integration hosting branch:

(Note: This will remove any other gh-pages site staged on that branch).

npm run deploy:gh-pages
npm run deploy:gh-pages -- --remote origin  # same thing
# Visit http://fork.github.io/numenta-web/

Shared

Push build to shared upstream:gh-pages integration hosting branch:

(Note: This will remove any other gh-pages site staged on that branch).

# Deploy master branch public/ to upstream:gh-pages branch
npm run deploy:gh-pages -- --remote upstream

# Visit http://numenta.github.io/numenta-web/

Staging and Production

Numenta handles builds and deployments for the Staging/Production runways in our internal Continuous Integration tooling.

Guidance

Code standards are handled by their respective linters and lint configs (for example, see the local file .eslintrc.json).

Components

Pages and Main Sections:
- Main Sections (pages grouped on our Wikipedia-like single-page app homepage) have their actual content in each pages' pages/*/_Section.jsx file
  - These main Sections are exposed as individual Pages via each pages' default pages/*/index.jsx component
- Regular Pages (non-Main Sections) are fully contained in the usual default pages/*/index.jsx location
Each React Component should return 1 small element
Include spaces manually around React Elements in JSX with: {' '}
Custom React context which is available (in addition to Gatsby defaults):
- config = Site config object (see: config.toml).
- manifest = Site package.json manifest object vars like repo, 'version`
- stamp = Build start timestamp string (for cache-busting)
Make sure to use the prefixLink() helper function on all internal links. This should be handled auto-magically for you already, but if you have trouble with links on staging, this may be the problem. Try to keep this working so that each developer can run their own demo sites on gh-pages.

Content

Markdown link target filenames with spaces must be quoted: [link text]("spaces in filename.txt")
Markdown YAML headmatter: be careful with quotes and escaping titles, etc.
Beware extra Markdown typographer shortcuts
Internal flat markdown auto-links (http://numenta.com/htm-studio/) may break on staging servers, use markdown style instead: [http://numenta.com/htm-studio/](/htm-studio/)
Search Engine Optimization (SEO) notes:
- Make sure to follow the Link and URL Format notes further below.

Links and URLs

Link Text

Use meaningful and semantic text for links, which describes what will be experienced at the destination of the link.
Avoid over-generalized link text, like "click here".

URL Format

URLs should end with / (slash)
Examples of ideal URLs detailed below:
- http://numenta.com/
- http://numenta.com/machine-intelligence-technology/
- http://numenta.com/business-strategy-and-ip/#licenses
- http://numenta.org/
- http://numenta.org/htm-school/

Possible Link Situations

Google Analytics should be tracking pages and events for all Situations in the matrix below.

Host	Type	.jsx Source	.md Source
Internal	Path	View	View
Internal	Anchor	View	View
Internal	Asset (/assets/*)	View	View
Internal	Asset (*/.pdf)	N/A	View
External	Path	View	View
External	Anchor	View	View
External	Protocol	View	View

Packages

Use exact versions for dependencies in package.json
Keep packages as up-to-date as possible: npm outdated -depth 0
Update and test 1 package at a time for safety
These packages have breaking updates which it seems we'll be skipping for now (at least until Gatsby, etc., update to work with them):
- history@3 history@4
- react-router@3
- [email protected]

Styles

CSS Module Composition order:

Compose from Tachyons classes
Compose from Site Theme classes (Numenta colors)
Compose from _local_file_custom classes
Specific custom CSS overrides

Example:

._visited:visited {
  color: #1aa0db;
}

.iconlink {
  composes: dim from 'tachyons';  /* 1. */
  composes: link from 'tachyons';
  composes: color-blue from '../../assets/css/theme.css';  /* 2. */
  composes: _visited;  /* 3. */
  opacity: 0.5;  /* 4. */
}
