Introducing catalogs: customized, managed open source. Free demo.

listr is a npm library included in the Tidelift Subscription

Tidelift is working with the maintainers of listr and thousands of other projects to provide application development teams with catalogs of issue-free open source software that “just works.”

Free Demo

With a managed open source subscription from Tidelift, you’ll be able to create your own customizable catalogs of known-good, proactively maintained JavaScript, Python, Java, PHP, Ruby, and . NET components. Accelerate your adoption of open source without the burden of managing it yourself and without sacrificing security, maintainability, or licensing compliance.

About listr

listr is a terminal task list available via the npm package manager. listr maintainer and creator, Sam Verschueren, maintains listr via the Tidelift Subscription. listr is used by more than 165,000 repositories and over 1,000 other projects depend on listr.

listr does the following:

  • A task can return different values. If a task returns, it means the task was completed successfully. If a task throws an error, the task failed.
  • A task can also be async by returning a Promise. If the promise resolves, the task completed successfully, it it rejects, the task failed.
  • A task can also return an Observable. The thing about observables is that it can emit multiple values and can be used to show the output of the task.
  • It's also possible to return a stream. The stream will be converted to an Observable and handled as such.
  • Optionally specify a skip function to determine whether a task can be skipped.

You can learn more about listr on the project repo.
