A React cron editor with antd inspired by jqCron
npm install react-js-cronbash
NPM
npm install react-js-cron
Yarn
yarn add react-js-cron
`
Usage
`jsx
import { Cron } from 'react-js-cron'
import 'react-js-cron/dist/styles.css'
export function App() {
const [value, setValue] = useState('30 5 1,6')
return
}
`
Don't forget to import styles manually:
`jsx
import 'react-js-cron/dist/styles.css'
`
Converter
If you want to use the converter that react-js-cron uses internally, you can import it into your project:
`jsx
import { converter } from 'react-js-cron'
const cronString = converter.getCronStringFromValues(
'day', // period: 'year' | 'month' | 'week' | 'day' | 'hour' | 'minute' | 'reboot'
[], // months: number[] | undefined
[], // monthDays: number[] | undefined
[], // weekDays: number[] | undefined
[2], // hours: number[] | undefined
[1], // minutes: number[] | undefined
false // humanizeValue?: boolean
)
console.log('cron string:', converted)
`
`
cron string: '1 2 *'
`
The converter can also be helpful for parsing a string. Note that Sunday is represented as 0 in the output array but can be either 0 or 7 in the cron expression.
`jsx
import { converter } from 'react-js-cron'
const [minutes, hours, daysOfMonth, months, daysOfWeek] =
converter.parseCronString('0 2,14 1-5')
console.log('parsed cron:', {
minutes,
hours,
daysOfMonth,
months,
daysOfWeek,
})
`
`
parsed cron: {
minutes: [0],
hours: [2, 14],
daysOfMonth: [],
months: [],
daysOfWeek: [1, 2, 3, 4, 5]
}
