Bindings for node-cron, a tool that allows you to execute something on a schedule. This is typically done using the cron syntax:
* * * * * *
┬ ┬ ┬ ┬ ┬ ┬
│ │ │ │ │ │
│ │ │ │ │ └ day of week (0 - 6, or sun - sat), 0 is Sunday
│ │ │ │ └───── month (0 - 11, or jan - dec)
│ │ │ └────────── day of month (1 - 31)
│ │ └─────────────── hour (0 - 23)
│ └──────────────────── minute (0 - 59)
└───────────────────────── second (0 - 59, OPTIONAL)
Learn more about the syntax at crontab.guru (NB it does not have the seconds parameter and months start at 1 (this lib has 0-indexed months)).
yarn add rescript-cron
Then add rescript-cron as a dependency to bsconfig.json:
"bs-dependencies": [
+ "rescript-cron"
]open RescriptCron
// Make a job that will fire every second when started
let job =
CronJob.make(
`CronString("* * * * * *"),
_ => Js.log("Just doing my job"),
(),
);
// Firing every second, printing 'Just doing my job'
start(job);
let time =
CronTime.make(`JsDate(Js.Date.fromString("2021-04-11T10:20:30Z")), ());
// setTime will stop the current job, and change when it will fire next
setTime(job, time);
// It will now fire once in april 2021
start(job);The tests have more examples of how to use these bindings.
