Keboola Connection UI

User interface for Keboola Connection

Development

• Clone the repo
• Install dependencies npm install
• Server, watch and test with live reload npm start
• Open this url in your browser http://localhost:3000/?token=YOUR_STORAGE_API_TOKEN

Application will be opened in your browser and will be hot reloaded after each change in source files.

Build dist package

• npm run build (It is executed by Travis after each push)

Application Architecture

• Single page application running in browser data fetching from Keboola REST APIs.
• Written in ES2015 (ES6) compiled to JS using Babel (older parts are written in Coffeescript).
• Bundled by Webpack.
• View layer is composed by React components
• Flux Architecture with unidirectional data flow controlling whole application. Vanilla Flux implementation is used.
• React Router for routing
• Keboola Bootstrap for UI components style. It is based on Twitter Bootstrap

React Components Best Practices

• It has to be pure it means rendered result is dependent only on components props and state. PureRenderer mixin can be then utilized
• Component props and state should be Immutable structures
• Define Prop Types form component. It is validated in development runtime and also in build step using ESlint
• Separate component which involves some data fetching to container components holding the fetched state and simple component rendering the data received using props. Read more about this pattern
  • Most of component should be "dumb" only with props, these are easiest to understand and most reusabled. Only top level components and container component should be connected to Flux stores. state can be of course used for things like open modal or acccordion status or temporary edit values in modal.
  • If you want to enhance component behaviour or inject some data consider using High Order Components It allows great composability using functions.

UX Guidelines

• Try to reuse components from KBC Bootstrap
• Provide instant feedback for all actions.
• Provide confirmation and explanation for possibly destructive actions (delete configuration, run job)
• UI should be self explainable and it should guide you to required actions. e.q. Database extractor configuration flow.
• Data fetching
  • Render the page when the primary data are available.
  • Some additionally data can be fetched later, loader should be shown when data are not yet loaded.

HOW TO

Add assets

Whole application is bundled by Webpack, not just js and coffee script files but also stylesheets (less, css), media and image files. Assets should be loaded by require or import function.

Examples:

• CSS include
• Image
• mp3

Add New Component (extractor, writer or application)

• Component has to be first registered in Keboola Connection
  • Ask someone from Keboola to register the component (there will be API one day)
  • Registered component is available in components list https://connection.keboola.com/v2/storage
  • During development component should have flag excludeFromNewList. The component will not be listed on New Extractor page.
  • Working backend is not required, we can register empty component
• When the component is registered cached components list in ui should be updated
  • Copy content of components array and paste it to index.html
• Create test configuration of your component
  • Use curl or some http client to trigger Create Config API call
  • cUrl example curl -H "X-StorageApi-Token:YOUR_STORAGE_API_TOKEN" -d "name=My First Dropbox" https://connection.keboola.com/v2/storage/components/ex-dropbox/configs
• Create and register routes for new component
  • Components routes, you can just copy and modify ex-adform routes https://github.com/keboola/kbc-ui/blob/77ab46b41a473cf3ad8bab01b807f9bf74d7da47/src/scripts/modules/ex-adform/routes.js
  • Register routes https://github.com/keboola/kbc-ui/blob/77ab46b41a473cf3ad8bab01b807f9bf74d7da47/src/scripts/modules/components/Routes.coffee#L111
