Dynamically Adding Lit Elements into Page

Lit elements are an implementation of web components. Lit elements are useful because it encourages component reuse across different JavaScript frameworks, which leads to reduced development time.

The traditional usage of Lit elements / web components involves defining the component inside your html page, however there might be instances where you do not wish to modify the html page by introducing the web component markup. The introduced web components might serve only as an assistive means for using the page, but the html export of the page must remain immaculate.

Remove Falsey Values from an Array

Use without as a means to remove falsey values from your arrays. The first argument to the without method takes in an array which will represent the elements which are to be removed when found in the second argument array. You can include any values in the first argument array which you deem to be a "falsey" value.

R.without([false, null, ''], [false, null, '', 1, 2, null, 3, 4, false, 5]);

// Outputs
// [1, 2, 3, 4, 5]

Check Content-Type

Testing a simple static file server is made simple when using SuperTest. It permits for the testing of HTTP methods, content-type, response body and many more options.

Supposedly you wish to test a basic http server which serves the common zip, jpg, and html files. This server example uses only the native Nodejs modules: http, fs, and path:

Lorem Ipsum

Use this plugin to fill out placeholder paragraphs. Helpful to see how content flows in html in a layout template or to check for text overflows.

Compact Binary Format for JSON Data Transfer

When you wish to use JSON for its convenience, but also want to send the JSON using a more compact representation to save data that needs to be transfer, you will need to use an information encoder for JSON. These encoders tend to represent the JSON data in binary format for transfer and there are many out there.

Get Port

Getting an open TCP port is useful when you wish to run a server on a port without knowing which ports are currently available.

Alternative to Puppeteer for PDF Generation

While puppeteer is a popular option used for testing as well as pdf generation for webpages, playwright is also another option that can perform these tasks and more.
