Minify JSON/XML

[lucasschonn]

Since there is a 'Beautify JSON/XML' option, it would be useful to have the reverse—'Minify JSON/XML'—given that some web services reject the payload if it is formatted; currently, I have to use the VS Code minify extension when this is required.

There's no minify option yet as far as I can tell, but a pre-request script can do it, so you don't have to paste the body into VS Code every time:

const { mode, raw } = insomnia.request.body;
if (mode === 'raw' && raw) {
  let minified;
  try {
    minified = JSON.stringify(JSON.parse(raw));
  } catch {
    minified = raw.replace(/>\s+</g, '><').trim(); // XML
  }
  insomnia.request.body.update({ mode: 'raw', raw: minified });
}

The body in the editor stays formatted; only what gets sent is minified, and the Content-Type stays the same. One thing to watch: if your JSON has template tags outside quotes (like "count": {{ _.count }}), it won't parse, and the script leaves it as is.
