Install RME:
npm i rme.js
On an appropriate js file import what is needed. Possible imports below:
import {
createApp,
useValue,
Component,
useMessage,
useMessages,
useHashRouter,
useUrlRouter,
useOnLoadUrlRouter,
useRouter,
CSS,
script,
ready,
Elem,
Tree,
Http,
Fetch,
Key,
Browser,
Util
} from 'rme.js'
Download a script file and place it to a project folder or simply use a github online url as follows.
<script src="https://github.com/JamiLu/RME/releases/download/v2.0.13/rme.es5.min.js"></script>
Or use NPM
npm i rme.js
import { createApp, Component, useValue, Key } from 'rme.js'
Then simply copy paste code clips below to your js file and voilà.
Create the application by the createApp function.
createApp({
'#app': {
'div.container': {
ClickAndShowExample, // Component functions must be defined before
TodoExample, // you can reference them here.
FormExample,
FilterExample
}
}
});Below is shown the exmaple index.html. The first selector of the create app object should match the selector where the app is desired to be created.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>Demo</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
</head>
<body>
<div id="app"></div>
</body>
</html>The first exmaple demonstrates use case of the useValue function that can be used to share a value between components without passing it forward.
const [getValue, setValue] = useValue(0);
const UseValueExample = () => ({
button: {
text: `Press me ${getValue()}`,
onClick: () => setValue(val => val + 1)
}
});
Component(UseValueExample);The second exmaple introduces the second parameter of the component named ops. The ops parameter is an object that has operational functions of the component.
Below is shown the usage of the setState, updateState and asyncTask functions.
const TodoExample = ({ list = [] }, ops) => ({
'input[type=text][placeholder=Type & Press Enter to Add]': {
onKeyDown: event => {
if(event.key === Key.ENTER) {
ops.updateState(state => ({
list: state.list
? state.list.concat(event.target.value)
: [event.target.value]
}));
event.target.value = '';
}
}
},
button: {
text: 'Clear list',
onClick: () => ops.setState()
},
ul: {
li: 'What groceries should I buy?',
_: list.map((val) => ({ li: val }))
}
});
Component(TodoExample);The third example shows the two paramters of the component function named props and ops. Below is shown the usage of the updateState function.
const FormExample = ({ fname = '', lname = '' }, ops) => ({
p: `Welcome ${fname} ${lname}`,
Form: {
input: event =>
ops.updateState({ [event.target.name]: event.target.value })
}
});
const Form = ({ input }) => ({
'label[for=fname]': 'First name',
'input#fname[type=text][name=fname][placeholder=First name]': {
onInput: input
},
'label[for=lname]': 'Last name',
'input#lname[type=text][name=lname][placeholder=Last name]': {
onInput: input
},
});
Component(FormExample, Form);The fourth example combines the learned and demonstrates the usage.
const [getCountryList] = useValue([
{country: 'Finland', capital: 'Helsinki'}, {country: 'Sweden', capital: 'Stockholm'}, {country: 'Norway', capital: 'Oslo'},
{country: 'Iceland', capital: 'Reykjavik'}, {country: 'England', capital: 'London'}, {country: 'America', capital: 'Washington'},
{country: 'Mexico', capital: 'Mexico City'}, {country: 'Peru', capital: 'Lima'}, {country: 'Egypt', capital: 'Kairo'},
{country: 'China', capital: 'Beijing'}, {country: 'Japan', capital: 'Tokyo'}, {country: 'South Korea', capital: 'Seoul'},
{country: 'Malaysia', capital: 'Kuala Lumpur'}, {country: 'Namibia', capital: 'Windhoek'}, {country: 'South Africa', capital: 'Cape Town'}]);
const FilterExample = ({ rows }, ops) => {
if (!rows) {
ops.asyncTask(() => ops.setState({rows: getCountryList()}));
}
const filterList = (keyword) =>
getCountryList().filter((row) =>
`${row.country}${row.capital}`.toLowerCase()
.search(keyword) > -1);
return {
'input[type=text][placeholder=Type to Filter Country]': {
onInput: event =>
ops.setState({ rows: filterList(event.target.value) })
},
MyTable: { rows }
}
};
const MyTable = ({ rows = [] }) => ({
table: rows.map(row => ({
tr: [
{ td: row.country },
{ td: row.capital }
],
}))
});
Component(FilterExample, MyTable);Not comprehensive. Just to name few.
