HTML forms and surprises

If you are using Rails, Laravel, or AdonisJS (the only one's I know), then these inconsistencies are handled automatically for you.

HTML forms have particular serializing behavior attached to them that you need to understand and address to work with normalized data in your applications.

I see a few talking about it because we stopped using HTML forms with the rise of frontend frameworks. However, they are now returning to HTML forms, so I expect more developers to encounter these surprises.

Empty fields lead to empty strings

const path = require('path');
const exec = require('child_process').exec;

function run(command) {
  return new Promise((resolve, reject) => {
    exec(command, function (error, stdout, stderr) {
      if (error) {
        reject(error);
      } else {
        resolve(stdout);

In yesterday's post I said, in relation to "how does .present? work on ActiveRecord::Relation", I said that present? performs an existence check SELECT 1 AS one FROM ... LIMIT 1 because it calls exists? underneath. This is actually wrong - it loads the relation.

Jonathan Mast corrected me on Twitter. It turns out, I should have paid closer attention! Here is the actual implementation of blank? on ActiveRecord::Relation on Rails master:

# Returns true if relation is blank.
def blank?
  records.blank?
end

JavaScript nl2br & br2nl functions

The exchange of new line & br HTML tag could refer to PHP - nl2br() function, which uses to inserts HTML line breaks before all newlines in a string.

These JavaScript functions consider whether to use insert or replace to handle the swap.

This disables app transport security and allows non-HTTPS requests.
Note: it is not recommended to use non-HTTPS requests for sensitive data. A better
approach is to fix the non-secure resources. However, this patch will work in a pinch.

To apply the fix in your Ionic/Cordova app, edit the file located here:

And add this XML right before the end of the file inside of the last </dict> entry:
