What performance issue do we need to solve?

When loading newdot in production, the static text assets (js, css, html, json, etc.) are not compressed. This leads to long loading time, expecially on slower networks.

For example when loading https://new.expensify.com we can observe in Safari devtools that no compression is done and the content is served as text/javascript for https://new.expensify.com/main-5c8169422a350d70ff13.bundle.js.

We can compare this with a request to a 3rd party library like appleid and see what it looks like when compressed.

If I compress this JS bundle file manually the size goes from 4.4mb to 1.2mb.

What is the impact of this on end-users?

App is slow to load initially on slower connections.

List any benchmarks that show the severity of the issue

Please also provide exact steps taken to collect metrics above if any so we can independently verify the results.

Proposed solution (if any)

Enable compression of static assets.

List any benchmarks after implementing the changes to show impacts of the proposed solution (if any)

Collect network traces in Safari or Chrome devtools and check the size of various files.

It's not obvious to me why these aren't being served compressed so I opened a cloudflare ticket.

Having trouble getting a response from Cloudflare through our support ticket on this. I pinged our account team on this.
