kanjiapi-wrapper v1.1.5

kanjiapi-wrapper

A wrapper library for kanjiapi.dev. Provides (currently) in-memory only request caching, and wraps the api with a synchronous listener based model.

Installation

yarn add kanjiapi-wrapper / npm install kanjiapi-wrapper

Example usage

Generic usage:

const { Kanjiapi } = require('kanjiapi-wrapper')

const listener = () => {
    // Ask kanjiapi instance for data again and trigger UI redraws
}

const kanjiapi = Kanjiapi.build()
kanjiapi.addListener('listener_name', listener)

const result = kanjiapi.getKanji('字')
// { status: "LOADING", value: null }

// once the data is loaded, any registered listener functions will be called
// to notify the library client that there was a change
// after this point calling kanjiapi.getKanji('字') returns the success result:
// { status: "SUCCESS", value: { kanji: "字", ... } }

mithril.js example:

flems.io

const { Kanjiapi } = require('kanjiapi-wrapper')

const Kanji = {
    view: ({ attrs: { kanji } }) =>
        kanji.status === Kanjiapi.SUCCESS ?
            m('ul', kanji.value.meanings.map(meaning => m('li', meaning))) :
            kanji.status === Kanjiapi.LOADING ?
            'Loading' :
            'Error',
}

const Page = {
    oninit: ({ state }) => state.character = '字',
    view: ({ state, attrs: { kanjiapi } }) => [
        m(
            'input[type=text]',
            {
               oninput: e => state.character = e.target.value,
               value: state.character,
            },
        ),
        m(Kanji, { kanji: kanjiapi.getKanji(state.character) }),
    ],
}

const kanjiapi = Kanjiapi.build();
kanjiapi.addListener('app', m.redraw)

m.mount(document.body, { view: () => m(Page, { kanjiapi }) })

react.js example:

flems.io

const { Kanjiapi } = require('kanjiapi-wrapper')

const Kanji = ({ kanji }) =>
    kanji.status === Kanjiapi.SUCCESS ?
        <ul>
            {kanji.value.meanings.map(meaning =>
                <li key={meaning}>{meaning}</li>)}
        </ul> :
        kanji.status === Kanjiapi.LOADING ?
        <div>Loading</div> :
        <div>Error</div>

const App = ({ kanjiapi }) => {
    const [timestamp, setTimestamp] = React.useState(Date.now())
    kanjiapi.addListener('appState', () => setTimestamp(Date.now()))

    const [character, setCharacter] = React.useState('字')

    return <>
        <input
            type="text"
            value={character}
            onChange={e => setCharacter(e.target.value)}/>
        <Kanji kanji={kanjiapi.getKanji(character)}/>
    </>
}

this.kanjiapi = Kanjiapi.build()
ReactDOM.render(<App kanjiapi={kanjiapi}/>, document.getElementById('app'))

Result form:

All results have a status either of "LOADING", "SUCCESS", or "ERROR", and a value of the parsed API response.

{
    status: "LOADING" | "SUCCESS" | "ERROR",
    value: $RESPONSE,
}
