Components

DataList

Component that display list of data, optionally scrollable (but scrolling is turned on in default).

Props
  • data (object[]): List of objects that determines data supplied to RowComponent.
  • RowComponent (ReactComponent|ReactNode): Component or Element used as a list row. If custom root element prop no supplied, then it's table and so this component should have tr as a root element to work properly.
  • noDataMessage (ReactNode [optional]): Message displayed when data list is empty. Default is 'No data'.
  • scrollable (boolean [optional]): Wheather scrollbars should be displayed when content overflow container. Default is true.
  • element (Component|string): Determine type of list root element.
Style

It's recommended to style scrollbar thumb using widget-data-list__scrollbar-thumb class name, because in default it's rgba(0, 0, 0, 0). Below is a simple example of styling thumb (but most time it's all you need)

.widget-data-list__scrollbar-thumb {
    background-color: grey;
    border-radius: inherit;
}

Example

import { DataList } from '@ackee/lucas';

const data = [
    { id: 1, text: 'Text 1' },
    { id: 2, text: 'Text 2' },
    { id: 3, text: 'Text 3' },
];

const CustomRowComponent = ({ id, text }) => (
    <tr>
        <td style={rowStyle}>{id}</td>
        <td style={rowStyle}>{text}</td>
    </tr>
);

React.render(
    <div>
        <DataList data={data} RowComponent={CustomRowComponent} noDataMessage="Data list is empty" />
    </div>
)
));

Prop types

childrenPropType

Prop type shape for children.

Example

import { childrenPropType } from '@ackee/lucas'

MyComponent.propTypes = {
    children: childrenPropType,
};

HOC

errorBoundary(ErrorComponent): BoundedComponent

High order component for setting error boundaries up. Implementation is very similar to that described by React authors.

Arguments

ErrorComponent: React component that shows the error. Receives

  • prop error which is occured error
  • all the props supplied to BoundedComponent
Returns

Component that catch any unexpected error that occured anywhere in subtree and invoke LOG_ERROR action

Example

// components/SimpleError.js
const SimpleError = ({ error }) => (
    <div>
        Error occured!:
        <code>{error.message}</code>
    </div>
);

// components/MainContent.js
const MainContent = () => (
    <div>
        <p>Error will be caught up</p>
        {/* Click on the button bellow generates uncaught error  */}
        <button onClick={(e) => e.callNonExistingFunction()}>Do error</button>
    </div>
);

// containers/MainContent.js
import { errorBoundary } from '@ackee/lucas';
import { compose } from 'redux';
import MainContent from '../components/MainContent';

compose(
    errorBoundary(SimpleError),
)(MainContent);

loadable(LoaderComponent: Component, defaultText?: string): (MyComponent) => LoadableMyComponent

High order component that wraps your content component with supplied loader and pass prop showLoader just to the loader.

HOC accepts two arguments:

  • LoaderComponent - component that is used as a loader, so it's displayed while showLoader is truthy
  • defaultText [optional] - default text that is provided to LoaderComponent unless loaderText prop is supplied to LoadableComponent

Wrapped loadable component accepts two more props:

  • showLoader - controls if loader is visible
  • loaderText [optional] - text that is provided into LoaderComponent

LoaderComponent receives loadable content (the component(s) hidden behind loader until load finish) as a children and two props:

  • show - loader visibility flag
  • text - loader text

Example

// components/Loader.jsx
const Loader = ({ children, show, text }) => (
    <div>
        { children }
        { show && <div className="loader">{text}</div> }
    </div>
);

export default Loader;
 
// containers/Users.js
import { loadable } from '@ackee/lucas';
import Users from '../components/Users';
import Loader from '../components/Loader';

export default compose(
    connect(
        state => ({
            showLoader: isFetchingUsersSelector(state),
        })
    )
    loadable(SimpleLoader),
)(Users);

makeDropzone(GraphicComponent): DropzoneComponent

High order component for easy making of file upload component with file dropzone.

Arguments
  • GraphicComponent: React component that creates dropzone graphic.
Returns

Component that receives two extra props:

  • isMouseOver (boolean): Determine if user drags with mouse over zone. Useful for changing dropzone style.
  • uploadState (FS): Actual state of file upload
File state

File upload state, accessible as a property of HOC, so makeDropzone.FS.

enum FS {
    failed,
    pending,
    uploading,
    uploaded
}

Example

// components/DropArea.js
const DropArea = ({ isMouseOver, uploadState }) => (
    <div style={{ backgroundColor: isMouseOver ? 'yellow' : 'grey' }}>
        <span className="button--blue button">
            {
                uploadState === makeDropzone.FS.uploaded || uploadState === makeDropzone.FS.failed 
                    ? 'Change'
                    : 'Select'
                }
        </span>
    </div>
);

// containers/Dropzone.js
import { makeDropzone } from '@ackee/lucas';
import { compose } from 'redux';
import DropArea from '../components/DropArea';

export default compose(
    makeDropzone,
)(DropArea);

// components/UploadImages.js
import containers from '@ackee/lucas';
import DropArea from '../containers/Dropzone';

const UploadImages = () => (
    <Dropzone
        onDrop={handleFilesDrop}
        input={{
            accept: 'image/png, image/jpeg',
            multiple: boolean,
        }}
    />
)

pure(equalityChecker): (UnpureComponent) => PureComponent

Makre provided component pure - it means that component not rerender until it's props change.

Arguments
  • equalityChecker (function(prevProps, nextProps):bool [optional]) - Function that returns boolean which determines if prev props are equal to next props. You can provide your own eqaulity checker, if you don't provide equality checker, lodash's isEqual function is used.

Returns: Function that accepts UnpureComponent (React component that should be optimilized for useless rerenderes) and return PureComponent (component that rerender only if their props change). Change is determined either by equality checker.

Example - custom equality checker

import { pure } from '@ackee/lucas';
import { compose } from 'redux';

const customEqualityChecker = (props, nextProps) => {
    return props.data.changableProp === nextProps.data.changableProp;
};

compose(
    pure(customEqualityChecker),
)(DataConsumerComponent);

Example - default equality checker

import { pure } from '@ackee/lucas';
import { compose } from 'redux';

compose(
    pure(),
)(DataConsumerComponent);

Action types

Logging action types

  • LOG_ERROR
import { actionTypes } from '@ackee/lucas';
import { takeEvery } from 'redux-saga/effects';

takeEvery(actionTypes.logging.LOG_ERROR, function* (action) {
    const { error, extra } = action;

    console.log(error, extra);
});
