🚀 Meteor 3.5-beta: Change Streams & Performance improvements

[wreiske]

It was originally a mixture of Blaze / Bootstrap / Ionic… Used meteor user-status to determine who was actively actually looking at the dashboard (bottom left avatars show activity in real-time like the rest of the dashboard)

Well, after 2 days of Opus 4.6 going at it and a little hand holding… it’s completely re-written in Typescript, React 19, TailwindCSS 4 and running smoothly! 1.11.1 to 3.5-beta.4 in 2 days!

This tool was my take on real time infrastructure monitoring before grafana was cool . Plus… it’s still more real-time than the “auto refresh” you get with tools like grafana/zabbix.

Another successful migration with this workflow:

• Open VS code and start a new workspace
• Go to File - > Add Folder to Workspace
• Add your existing / old meteor project
• git clone https://github.com/wreiske/meteor-react-tailwind-prettier-starter project-react somewhere on your machine
• Go to File - > Add Folder to Workspace → select project-react
• Open Copilot, make sure it’s in “Plan” mode and tell it that there are two projects in the workspace.

Here’s what I used:

There are two projects in the workspace.

statengine and statengine-react

statengine is an old Meteor 1 application that we need to rewrite into the new modern Meteor 3.4 stack inside of statengine-react, which is currently a “TODO example app” that is a “starter” template for React19, TailwindCSS 4, Typescript, etc.

Please come up with an extensive plan for how we can handle a complete migration and cleanup of the original statengine code base into the new format.

After a little while it will have a plan. review it and make any edits you think are required… This was my response:

OK. Let’s do it. Start the plan. Please make sure you put the entire plan into a markdown file and as you go through your plan, check off each item, so we know where we left off.

Also, i’d like to use luxon instead of date-fns.

And then hand hold it with a few “continue with the plan…” until it’s complete!

This workflow has allowed me to migrate several old projects with very little hand holding and my typical “format, lint, commit, push” prompt and copilot instructions to keep code DRY, KISS, etc…

YMMV!

Going to do some serious code review before pushing out to a test cluster node and then I’ll check our CPU / Memory / etc old vs new for a few days and see what improvements we get!

Congrats! The new UI looks great.

Excited to hear what perf shows on 3.5
