Tableschema-ui NPM

tableschema-ui

A web UI for creating, editing and validating Table Schemas.

Features

render - framework-agnostic component render
List of components:
- EditorSchema - table schema editor widget

Getting Started

You could use this components in plain JavaScript code or mixing with any modern framework (with native support for React). To render EditorSchema you have use tableschemaUI.render(tableschemaUI.<Component>, props, element) function.

First add bootstrap styles and scripts:

Installation

NPM

Install the package in your terminal $ npm install --save tableschema-ui

The package could be used as tableschema-ui package from NPM:

const tableschemaUI = require('tableschema-ui')

const props = '<YOUR-PROPS>'
const element = document.getElementById('component')
tableschemaUI.render(tableschemaUI.Component, {...props}, element)

CDN

The package could be used as pluggable script from CDN:

<div id="component"></div>
<script src="//unpkg.com/tableschema-ui/dist/tableschema-ui.min.js"></script>
<script>
  var props = '<YOUR-PROPS>'
  var element = document.getElementById('component')
  tableschemaUI.render(tableschemaUI.Component, {...props}, element)
</script>

Documentation

React

You could use presented components as native React component (import from tableschema-ui/lib to get native React support):

const React = require('react')
const ReactDOM = require('react-dom')
const tableschemaUI = require('tableschema-ui/lib')

const props = '<YOUR-PROPS>'
const element = document.getElementById('component')
ReactDOM.render(<tableschemaUI.Component ...props />, element)

Angular

The package's components could be used as angular component:

const {Component, Input} = require('@angular/core')
const tableschemaUI = require('tableschema-ui')

@Component({
  selector: 'component',
  template: '<div id="component"></div>'
})
class Report {
  @Input() <YOUR_PROPS>: any;
  ngAfterViewInit() {
    const element = document.getElementById('component')
    tableschemaUI.render(tableschemaUI.Component, {...this.props}, element)
  }
}

Vue

The package's components could be used as vue component:

const tableschemaUI = require('tableschema-ui')

const Report = {
  props: [<YOUR_PROPS>],
  template: '<div id="component"></div>',
  mounted() {
    const element = document.getElementById('component')
    tableschemaUI.render(tableschemaUI.Report, {...this.props}, element)
  },
}

Working with Render

To render one of the provided component render function should be used. Let's see on the basic usage example:

// Render
const props = {key: value}
const element = document.getElementById('component')
const component = tableschemaUI.render(tableschemaUI.Component, {...props}, element)

// Dispose
component.dispose()

Working with EditorSchema

This component provides a simple Table Schema editor. Let's see on the basic usage example:

// Render
const props = {
    source: 'http://example.com/data.csv',
    schema: '{"fields": []}',
    onSave: (schema, error) => {
        handleError(error)
        handleSchema(schema)
        component.dispose()
    },
}
const element = document.getElementById('schema-editor')
const component = tableschemaUI.render(tableschemaUI.EditorSchema, {...props}, element)

If data source is provided and data schema is not provided than it will be inferred from the data. The component support various options to provide the source/schema including URL and File object.

Contributing

The project follows the Open Knowledge International coding standards. There are common commands to work with the project:

$ npm run dev
$ npm run build
$ npm run test

Statefull components use redux combined with immer (see src/store.js). Instead of classical initialState/actionCreators/reducers there are:

initial - initial store state
handlers - callbacks available in components to dispatch actions
mutations - immer based state reducers. The same as redux reducers but it allows us to change state in-place preserving immutability on the system level (see redux-box)
processor - a mutation which is called after every state change
