Filter Queries - Example Use Cases

Here are a few example use cases, these use cases combine filter with other parameters to make useful API queries. The syntax for any of this may change between now, implementation, and release - they're meant as illustrative examples :)

Fetch 3 posts with tags which match 'photo' or 'video' and aren't the post with id 5.

api.posts.browse({filter: "tags:[photo, video] + id:-5", limit="3"});

GET /api/posts?filter=tags%3A%5Bphoto%2Cvideo%5D%2Bid%3A-5&limit=3

const nats = stream(n => n + 1, 1);
const evenNumbers = map(n => n * 2, nats);

console.log(take(10, evenNumbers));
// [2, 4, 6, 8, 10, 12, 14, 16, 18, 20]

Prerequisites : the letsencrypt CLI tool

This method allows your to generate and renew your Lets Encrypt certificates with 1 command. This is easily automatable to renew each 60 days, as advised.

You need nginx to answer on port 80 on all the domains you want a certificate for. Then you need to serve the challenge used by letsencrypt on /.well-known/acme-challenge. Then we invoke the letsencrypt command, telling the tool to write the challenge files in the directory we used as a root in the nginx configuration.

I redirect all HTTP requests on HTTPS, so my nginx config looks like :

server {

Handling Errors

Express.js makes it a breeze to handle errors in your routes.

Express lets you centralizes your error-handling through middleware.

Let's look at patterns for how to get the most out of your error-handling.

First, our error-handling middleware looks like this:

javilobo8

axios({
  url: 'http://localhost:5000/static/example.pdf',
  method: 'GET',
  responseType: 'blob', // important
}).then((response) => {
  const url = window.URL.createObjectURL(new Blob([response.data]));
  const link = document.createElement('a');
  link.href = url;
  link.setAttribute('download', 'file.pdf');
  document.body.appendChild(link);

  var sandbox;
  
  before(function(){
    sandbox = sinon.sandbox.create();
