Uppy Development

First clone and install the project:

git clone [email protected]:transloadit/uppy.git
cd uppy
npm install

Our website's examples section is also our playground, read "Website Development"'s "Local Previews" section to get up and running.

Tests

Unit tests are using Jest and can be run with:

npm run test:unit

For acceptance (or end to end) tests, we use Webdriverio. For it to run locally, you need to install selenium standalone server, just follow the guide to do so. You can also install Selenium Standalone server from NPM:

npm install selenium-standalone

And then launch it:

selenium-standalone start

After you’ve installed and launched the selenium standalone server, run:

npm run test:acceptance:local

Website Development

We keep the uppy.io website in ./website for so it's easy to keep docs & code in sync as we're still iterating at high velocity. For those reading this screaming murder, HashiCorp does this for all their projects, and it's working well for them on a scale vastly more impressive than Uppy's.

The site is built with Hexo, and Travis automatically deploys this onto GitHub Pages (it overwrites the gh-pages branch with Hexo's build at every change to master). The content is written in Markdown and located in ./website/src. Feel free to fork & hack!

Even though bundled in this repo, the website is regarded as a separate project. So it has its own package.json and we aim keep the surface where the two projects interface as small as possible. ./website/update.js is called during website builds to inject the Uppy knowledge into the site.

Local Previews

It's recommended to exclude ./website/public/ from your editor if you want efficient searches.

To install the required node modules, type:

npm install && cd website && npm install && cd ..

For local previews on http://127.0.0.1:4000 type:

npm start

This will watch the website, as well as Uppy, as the examples, and rebuild everything and refresh your browser as files change.

Then, to work on e.g. the XHRUpload example, you'd edit the following files:

atom src/core/Core.js \
  src/plugins/XHRUpload.js \
  src/plugins/Plugin.js \
  website/src/examples/xhrupload/app.es6

And open http://0.0.0.0:4000/examples/xhrupload/ in your webbrowser.

CSS Guidelines

The CSS standards followed in this project closely resemble those from Medium's CSS Guidelines. If it's not mentioned here, follow their guidelines.

Naming Conventions

This project uses naming conventions adopted from the SUIT CSS framework. Read about them here.

To quickly summarize:

Utilities

Syntax: u-[sm-|md-|lg-]

.u-utilityName
.u-floatLeft
.u-lg-col6

Components

Syntax: [-][-descendentName][--modifierName]

.twt-Button /* Namespaced component */
.MyComponent /* Components pascal cased */
.Button--default /* Modified button style */
.Button--large

.Tweet
.Tweet-header /* Descendents */
.Tweet-bodyText

.Accordion.is-collapsed /* State of component */
.Accordion.is-expanded

SASS

This project uses SASS, with some limitations on nesting. One-level deep nesting is allowed, but nesting may not extend a selector by using the & operator. For example:

/* BAD */
.Button {
  &--disabled {
    ...
  }
}

/* GOOD */
.Button {
  ...
}

.Button--disabled {
  ...
}

Mobile-first Responsive Approach

Style to the mobile breakpoint with your selectors, then use min-width media queries to add any styles to the tablet or desktop breakpoints.

Selector, Rule Ordering

• All selectors are sorted alphabetically and by type.
• HTML elements go above classes and IDs in a file.
• Rules are sorted alphabetically.

/* BAD */
.wrapper {
  width: 940px;
  margin: auto;
}

h1 {
  color: red;
}

.article {
  width: 100%;
  padding: 32px;
}

/* GOOD */
h1 {
  color: red;
}

.article {
  padding: 32px;
  width: 100%;
}

.wrapper {
  margin: auto;
  width: 940px;
}
