![]() Deno Land strives to ease web development by removing config and unnecessary boilerplate. But developers just want to focus on business logic. Modern software uses cloud infrastructure, dissects boilerplate code, and manages intricate configurations. In explaining the rationale behind Deno Cron, Deno Land said building for the web has become increasingly complex. Deno Land also is working to support a JavaScript-friendly API to specify the cron schedule. Overlapping cron jobs can lead to unintended issues and require extra logic to avoid, Deno Land said Deno Deno Cron sidesteps that. Hence, if an operator schedules a job to run every 10 minutes but the task takes 30 minutes, Deno Cron automatically skips the next scheduled run until the task is finished. Unlike cron jobs on Unix and Linux, Deno Cron executions do not overlap. Deno Cron handlers can perform actions such as updating state in Deno KV, pinging a website, sending email, initiating a database backup, and calling an API at regular intervals. ![]() Deno Cron’s schedule uses the Unix cron format and the UTC time zone. ![]() Deno Land, the developers of the Deno TypeScript/JavaScript runtime, have introduced Deno Cron, a feature the company describes as an easy way to create scheduled jobs.Īnnounced November 29 and available behind the -unstable flag in Deno 1.38, Deno.cron() is a function that takes three parameters: the name of the scheduled job, the schedule, and the handler, the latter being the function executed on the schedule provided.
