How To Install node-jest-worker on Debian 11
Introduction
In this tutorial we learn how to install node-jest-worker on Debian 11.
What is node-jest-worker
node-jest-worker is:
jest-worker provides a
Promisebased interface, minimum overhead and bound workers.
The module works by providing an absolute path of the module to be loaded in
all forked processes. Files relative to a node module are also accepted. All
methods are exposed on the parent process as promises, so they can be
await‘ed. Child (worker) methods can either be synchronous or asynchronous.
The module also implements support for bound workers. Binding a worker means
that, based on certain parameters, the same task will always be executed by
the same worker. The way bound workers work is by using the returned string
of the computeWorkerKey method. If the string was used before for a task,
the call will be queued to the related worker that processed the task earlier;
if not, it will be executed by the first available worker, then sticked to the
worker that executed it; so the next time it will be processed by the same
worker. If you have no preference on the worker executing the task, but you
have defined a computeWorkerKey method because you want some of the tasks
to be sticked, you can return null from it.
