React Blueprint

Travis node npm Dependency Status npm npm npm

React Blueprint is a react-native insipred web app generator and tool set.

It uses the best libraries for React development without being too opinionated. We make no assumptions on how your app should look, but instead provide a strong architecture to build upon.

Included Libraries

Quick Start


  1. Install the command line interface - npm i -g react-blueprint
  2. Generate your project - react-blueprint init [app-name]
  3. Start your app - cd [app-name] && npm start

The dev server will be running on localhost:3001 by default.

Removing Docs

Upon creation of your project, you will notice that these docs are rendered in your application. They have been included to provided some examples of usage. All the docs are located in src/components/Docs. To remove the docs, open the projects main index at src/index.js.

  1. Remove the import of DocRoutes on line 24
  2. Change reference to DocRoutes to Routes on line 42

When complete your new index should look as follows:

import 'babel-polyfill';
import React from 'react';
import { render } from 'react-dom';
import { Provider } from 'react-redux';
import { syncReduxAndRouter } from 'react-router-redux';
import {
    browserHistory as history
} from 'react-router';
import { App } from 'containers';
import { DevTools, Routes } from 'components';
import { getHydratedState } from 'utils/localStorage';
import Store from 'stores/Store';
import rootReducer from 'reducers';
const store = Store(rootReducer, getHydratedState());
const dest = document.getElementById('app-container');
// Enable Debugger
if (__DEVELOPMENT__) {
  window.React = React;
syncReduxAndRouter(history, store, state => state.route);
if (__DEVTOOLS__ && !window.devToolsExtension) {
    // Dev Render
        <Provider store={store}>
                <Router history={history}>{Routes}</Router>
                <DevTools />
} else {
    // Production Render
        <Provider store={store}>
            <Router history={history}>{Routes}</Router>

At this point you can safely remove the Docs directory from src/components and your app will be rendering the blank AppContainer located at src/containers/AppContainer.


You can find example usage in the previously mentioned Docs component. It has been structured to simulate the applcation structure (don't structure your components like this).

The main container component Docs resides at src/components/Docs/containers/Docs.js.

React Blueprint is equipped with Redux DevTools increase visibility into and control of your applications state. All Redux actions are logged in the console using redux-logger.

In addition to the logger, we have provided Redux DevTools in the form of a panel overlay. See usage below:


  • H Toggle the visibilty of the DevTools panel
  • Q Change the DevTools panel position


React Blueprint components can be used independently of the project generator. If you generate a project using the React Blueprint CLI then the component library will be installed automatically. Otherwise install React Blueprint...

npm i react-blueprint --save

and import in your project

import { View, ScrollView, Dimensions } from 'react-blueprint';


A flexbox component.


<View row>
    <View auto row>
     <View column width="100px">
     <View className="red">Left</View>
        <View column width="100px">
            <View className="red">Left</View>
    <View row className="green">Hello test view</View>
<View column height="200px">
    <View column auto>
     <View style={{ color: "green"}} height="20px">Green</View>
        <View style={{ color: "red"}} height="20px">Red</View>
    <View style={{ color: "green" }}>Hello test view </View>


All props are optional.

Bool row

  • sets the flexDirection to row

Bool column

  • sets the flexDirection to column

Bool auto

  • sets the flex to '0 0 auto'

String | Number width

  • width can be either a number width={2}, this acts as flex-grow or a string with a unit (for example % or px)

it must be a valid css unit.

String | Number height

  • sets the height of the component

it must be a valid css unit

String className

  • className to apply to the component

Object style

  • Will be merged the flex style. This allows you to override the style.


A scrolling view component with rendering optimizations. Based on react-infinite with some additions and optimizations.


Elements of Equal Height

  • To use ScrollView with a list of elements you want to make scrollable, provide them to ScrollView as children.
<ScrollView containerHeight={200} elementHeight={40}>
    <div className="one"/>
    <div className="two"/>
    <div className="three"/>

Optimizations Disabled

  • A simple ScrollView with no optimizations.
<ScrollView containerHeight={200} optimizeRendering={false}>
    <div className="one"/>
    <div className="two"/>
    <div className="three"/>

Elements of Varying Heights

  • If not all of the children have the same height, you must provide an array of integers to the elementHeight prop instead.
<ScrollView containerHeight={200} elementHeight={[111, 252, 143]}>
    <div className="111-px"/>
    <div className="252-px"/>
    <div className="143-px"/>

Using the Window to Scroll (useWindowAsScrollContainer mode)

  • To use the entire window as a scroll container instead of just a single div (thus using window.scrollY instead of a DOM element's scrollTop), add the useWindowAsScrollContainer prop.
<ScrollView containerHeight={200} elementHeight={[111, 252, 143]}
    <div className="111-px"/>
    <div className="252-px"/>
    <div className="143-px"/>

As A Chat or Message Box (displayBottomUpwards mode)

  • ScrollView now supports being used as a chat box, i.e. appended elements appear at the bottom when added, and the loading of the next page occurs when the user scrolls to the top of the container. To do so, simply add the displayBottomUpwards prop.
<ScrollView containerHeight={200} elementHeight={[111, 252, 143]}
    // insert messages for subsequent pages at this point
    <div className="third-latest-chat"/>
    <div className="second-latest-chat"/>
    <div className="latest-chat-message"/>

Note on Smooth Scrolling

  • A wrapper div is applied that disables pointer events on the children for a default of 150 milliseconds after the last user scroll action for browsers with inertial scrolling. To configure this, set timeScrollStateLastsForAfterUserScrolls.

Static Methods

Function Infinite.containerHeightScaleFactor(Number number)

  • This function allows a value to be specified for preloadBatchSize and preloadAdditionalHeight that is a relative to the container height. Please see the documentation for those two props for further information on how to use it.

Instance Methods

Function scrollTo(Number top)

  • This function will set the scrollTop of the ScrollView. Useful if you want to programatically set scroll position.


React Node | [React Node] children

  • The children of the <ScrollView> element are the components you want to render. This gives you as much flexibility as you need in the presentation of those components. Each child can be a different component if you desire. If you wish to render a set of children not all of which have the same height, you must map each component in the children array to an number representing its height and pass it in as the elementHeight prop.

Bool optimizeRendering

  • Defaults to true. Setting optimizeRendering={false} will keep your children rendered in the dom. The elementHeight prop can also be ignored.

⚠️ This is only intended to be used for simple applications where the scroll content is relatively small. You will experience limitations in this mode.

Bool useWindowAsScrollContainer

  • Defaults to false. This option allows the window to be used as the scroll container, instead of an arbitrary div, when it is set to true. This means that scroll position is detected by window.scrollY instead of the scrollTop of the div that ScrollView creates. Using this option is a way of achieving smoother scrolling on mobile before the problem is solved for container divs.

Bool displayBottomUpwards

  • Defaults to false. This allows ScrollView to be used as a chatbox. This means that the scroll is stuck to the bottom by default, and the user scrolls up to the top of the container to load the next page. The children are displayed in the same order.

(Required) Number | [Number] elementHeight

  • If each child element has the same height, you can pass a number representing that height as the elementHeight prop. If the children do not all have the same height, you can pass an array which is a map the children to numbers representing their heights to the elementHeight prop.

Number containerHeight

  • The height of the scrolling container in pixels. This is a required prop if useWindowAsScrollContainer is not set to true.

Number | Object preloadBatchSize

  • Defaults to this.props.containerHeight * 0.5. Imagine the total height of the scrollable divs. Now divide this equally into blocks preloadBatchSize pixels high. Every time the container's scrollTop enters each of these blocks the set of elements rendered in full are those contained within the block and elements that are within preloadAdditionalHeight above and below it.

  • When working with the window as the scroll container, it is sometimes useful to specify a scale factor relative to the container height as the batch size, so your code does not need to know anything about the window. To do this, use Infinite.containerHeightScaleFactor. So, for example, if you want the preloaded batch size to be twice the container height, write preloadBatchSize={Infinite.containerHeightScaleFactor(2)}.

Number | Object preloadAdditionalHeight

  • Defaults to this.props.containerHeight. The total height of the area in which elements are rendered in full is height of the current scroll block (see preloadBatchSize) as well as preloadAdditionalHeight above and below it.

  • When working with the window as the scroll container, it is sometimes useful to specify this relative to the container height. If you want the preloaded additional height to be twice the container height, write preloadAdditionalHeight={Infinite.containerHeightScaleFactor(2)}. Please see preloadBatchSize for more details.

Function handleScroll(DOMNode node)

  • Defaults to function(){}. A function that is called when the container is scrolled, i.e. when the onScroll event of the infinite scrolling container is fired. The only argument passed to it is the native DOM Node of the scrolling container.

Number infiniteLoadBeginEdgeOffset

  • Defaults to undefined, which means that infinite loading is disabled. To disable infinite loading, do not provide this property or set it to undefined.

Regular Mode

  • When the user reaches this number of pixels from the bottom, the infinite load sequence will be triggered by showing the infinite load spinner delegate and calling the function onInfiniteLoad.

displayBottomUpwards mode

  • When the user reaches this number of pixels from the top of the container, the infinite load sequence will be triggered by showing the infinite loading spinner delegate at the top of the container and calling onInfiniteLoad.

Function onInfiniteLoad()

  • Defaults to function(){}. This function is called when the scroll exceeds infiniteLoadBeginEdgeOffset. Before this function is called, the infinite loading spinner is automatically turned on.

You can set up infinite scrolling with this function like this:

  1. Fetch a new page of records from the appropriate API
  2. When the AJAX call returns, send the new list of elements (with the items that were just fetched) back as the children of ScrollView.
  3. Set ScrollView's isInfiniteLoading prop to false to hide the loading spinner display

onInfiniteLoad relies heavily on passing props as a means of communication in the style of idiomatic React.

React Node loadingSpinnerDelegate

  • Defaults to <div/>. The element that is provided is used to render the loading view when ScrollView's isInfiniteLoading property is set to true. A React Node is anything that satisfies React.PropTypes.node.

Bool isInfiniteLoading

  • Defaults to false. This property determines whether the infinite spinner is showing.

Number timeScrollStateLastsForAfterUserScrolls

  • Defaults to 150 (in milliseconds). On Apple and some other devices, scroll is inertial. This means that the window continues to scroll for several hundred milliseconds after an onScroll event is fired. To prevent janky behavior, we do not want pointer-events to reactivate before the window has finished moving. Setting this parameter causes the Infinite component to think that the user is still scrolling for the specified number of milliseconds after the last onScroll event is received.

String className

  • Allows a CSS class to be set on the scrollable container.



Dimensions is a utiltiy that will get the width and height (including margin and borders) of a given element. You will need to ensure that your DOM is rendered before you can get the dimensions of a react element. However, Dimensions also supports window and document and their dimensions can be accessed immediately. It can also be invoked as a decorator.

Usage as Method

Dimensions([ window || document || element ]);


    width: [number],
    height: [number]

Window or Document

 * Window / Document example
import React, { Component } from 'react';
import { Dimensions } from 'react-blueprint';
export default class WindowExample extends Component {
    componentWillMount() {
            windowDimensions: Dimensions(window),
            documentDimensions: Dimensions(document)
    render() {
        return (
                <p>width: {this.state.documentDimensions.width}</p>
                <p>height: {this.state.documentDimensions.height}</p>

React DOM Component

React now exposes the DOM element of their DOM components (div, span, p, a, etc) through this refs.

 * React DOM Component Example
import React, { Component } from 'react';
import { Dimensions } from 'react-blueprint';
export default class ReactDOMComponent extends Component {
    componentDidMount() {
        let dimensions = Dimensions(this.refs.container);
        this.setState({ dimensions });
    render() {
        return (
            <div ref='container'>
                <p>width: {this.state.dimensions.width}</p>
                <p>height: {this.state.dimensions.height}</p>

Custom React Component

If you want to measure a custom component you will have to use ReactDOM.findDOMNode(this.refs.yourRef)

 * Custom Component Example
import React, { Component } from 'react';
import { findDOMNode as $ } from 'react-dom';
import { Dimensions } from 'react-blueprint';
export default class CustomComponentExample extends Component {
    componentDidMount() {
        let dimensions = Dimensions($(this.refs.container));
        this.setState({ dimensions });
    render() {
        return (
            <View ref='container'>
                <p>width: {this.state.dimensions.width}</p>
                <p>height: {this.state.dimensions.height}</p>

Usage as Decorator

You can decorate your custom classes with Dimensions and it will add a width and a height prop to your component. It also attaches a getDimensions() method which will return the components width and height. Anytime the window is resized the new dimensions will be computed and made available via props.

 * Decorated Component Example
import React, { Component } from 'react';
import { findDOMNode as $ } from 'react-dom';
import { Dimensions } from 'react-blueprint';
export default class DecoratorExample extends Component {
    render() {
        return (
                <p>width: {this.props.width}</p>
                <p>height: {this.props.height}</p>
class App extends Component {
    render() {
        return <DecoratorExample ref="decoratorExample" />
    getChildDimensions() {
        return this.refs.decoratorExample.getDimensions();
