More capable form controls | Articles | web.dev
The formdata event is a low-level API that lets any JavaScript code participate in form submission. Add a formdata event listener to the form you want to interact with. When a user clicks submit, the form fires a formdata event, which includes a FormData object that holds all of the data being submitted. Each formdata listener gets a chance to add to or modify the data before the form is submitted
ES feature: `globalThis`
Warning: This blog post is outdated. Instead, read section “globalThis” in “Exploring JavaScript”. The ECMAScript proposal “globalThis” by Jordan Harband provides a new standard way of accessing the global object. JavaScript’s global scope # JavaScript’s variable scopes are nested and form a tree whose root is the global scope. That scope is only the direct scope when a script runs in a web brows

Stop using Knex.js (and earn $30)
This is true about any SQL query builder. I chose to use knex.js as an example because it is the most popular SQL query builder in the Node.js ecosystem and we need an example. tl;dr; Knex.js (and other query builders) was designed to be a building block for ORMs; it does not add value when majority of the query is static. If you are evaluating alternative to Knex.js, I have since published anothe

GitHub - unshiftio/url-parse: Small footprint URL parser that works seamlessly across Node.js and browser environments.
url-parse was created in 2014 when the WHATWG URL API was not available in Node.js and the URL interface was supported only in some browsers. Today this is no longer true. The URL interface is available in all supported Node.js release lines and basically all browsers. Consider using it for better security and accuracy. The url-parse method exposes two different API interfaces. The url interface t
When a rewrite isn’t: rebuilding Slack on the desktop
Conventional wisdom holds that you should never rewrite your code from scratch, and that’s good advice. Time spent rewriting something that already works is time that won’t be spent making our customers working lives simpler, more pleasant, and more productive. And running code knows things: hard-won knowledge gained through billions of hours of cumulative usage and tens of thousands of bug fixes.
GitHub - jstransformers/jstransformer: Normalize the API of any JSTransformer.
Normalize the API of any jstransformer There are many good template engines and compilers written for Node.js. But there is a problem: all of them have slightly different APIs, requiring slightly different usage. JSTransformer unifies them into one standardized API. Code written for one transformer will work with any other transformer. There are over 100 transformers, ranging from Markdown parsers
