Exploring the Angular 4 Cronstrue Idea: Transforming cron syntax into readable strings[From CronJobs to Cronstrue]

Can anyone provide an example of using the cronstrue concept to convert cron expressions into human-readable strings within Angular 4?

I am looking for a library or plugin in Angular 4 that can convert cronjob schedule expressions into readable text [cronstrue].

If I have a cron expression like:

"0 15 * * * ?"

The desired result is to have it output as follows:

"At second :00 of minute :15 of every hour"

Answer №1

cRonstrue is available as a UMD module, allowing it to function in an AMD, CommonJS, or browser global environment.

To start using the module, begin by installing it:

npm install cronstrue

After installation, depending on your specific context of use, import the module accordingly:

Below are some usage examples showcasing how cRonstrue interprets different cron expressions:

TypeScript

import cronstrue from 'cronstrue';


cronstrue.toString("* * * * *");
> "Every minute"

cronstrue.toString("0 23 ? * MON-FRI");
> "At 11:00 PM, Monday through Friday"

cronstrue.toString("23 12 * * SUN#2");
> "At 12:23 PM, on the second Sunday of the month"

cronstrue.toString("* * * ? * 2-6/2", { dayOfWeekStartIndexZero: false});
> "Every second, every 2 days of the week, Monday through Friday"

cronstrue.toString("* * * * *");

"Every minute"

cronstrue.toString("0 23 ? * MON-FRI");

"At 11:00 PM, Monday through Friday"

cronstrue.toString("23 12 * * SUN#2");

"At 12:23 PM, on the second Sunday of the month"

cronstrue.toString("* * * ? * 2-6/2", { dayOfWeekStartIndexZero: false});

"Every second, every 2 days of the week, Monday through Friday"
