A Toy Bug Tracker in JavaScript

This Could Be Better

The JavaScript code below implements a rudimentary bug tracker, or, perhaps more accurately, a task tracker. To see it in action, copy it into an .html file and open that file in a web browser that runs JavaScript.

It’s not actually useful in its current form, of course, as all the users are hardcoded and any tasks added during the session aren’t persisted anywhere. I’d also like to implement parent-child relationships among tasks and add support for generalized attributes. This program is intended mostly as a basis for further work.

Node.js APIs caching made simple!

The JavaScript and Node.js Blog

In this article we discuss how we can easily implement APIs caching in distributed solutions.
A Node.js implementation is described, in concrete the great http-cache-middleware module:

const middleware = require('http-cache-middleware')()
const service = require('restana')()
service.use(middleware)

service.get('/expensive-route', (req, res) => {
  const data = // heavy CPU and networking tasks...
 
  res.setHeader('x-cache-timeout', '1 week')
  res.send(data)
})

But, what is caching?

Acacheis a hardware or software component that stores data so that future requests for that data can be served faster; the data stored in a cache might be the result of an earlier computation or a copy of data stored elsewhere. Acache hitoccurs when the requested data can be found in a cache, while acache missoccurs when it cannot. Cache hits are served by reading data from the cache, which is faster than recomputing a result or reading from a slower data store; thus, the more…
