Bundle Explorer (prototype) shows modules, sizes from InstallBundle tx

[dckc]

@anilhelvaci asked about the cost of deploying bundles and if there's a way to reduce bundle size. I offered to take a look at their bundle for opportunities.

I made a quick-n-dirty bundle explorer:

• experimental deploy: https://bexp.netlify.app/
• https://github.com/agoric-labs/bundle-tool2

It started as a bundle explorer gist to look at the swingset.MsgInstallBundle transaction for the crabble contract on agoricdev-21.

.

To use it, you currently have to download unbundle.html an unbundle.js and use a static HTTP server. I suppose I could host it somewhere...

Browsing through the bundle contents, I'm reminded that in due course, you should only need to pay for new modules:

• share Zoe/ERTP libraries among contracts #2391

In the shorter term, there's some possible clean-up we are looking into:

• End runtime imports of types modules #6512

also:

• handles other nodes (e.g. main.rpc.agoric.net)
• computes bundle storage cost

For example: KREAd aux proposal bundle tx 95B037...

I looked into differential bundle loading.

The last half of the rows in summary.csv suggest that we'd save about 90% on contract uploads if we exclude stuff that's already on chain.

And the remaining 10% is dominated by compartment-map.json.

@dckc thanks for Bundle Explorer. I took the code and ported it to the explorer I am playing with using Appsmith.

Following features were added in it.

• Load transactions that have bundle installed in them
• Capability to inspect the content of the code files in the bundle
• Compare the bundle code with github version
• Share the bundle links with others

I added showing the bundle hash in the gist
haven't re-deployed to netlify

I'm starting to add bundle upload. Things were getting a little complex, so I started migrating to vite + lit-ts

I tried adding a download as zip feature, but got bogged down.
