browser version

[odyslam]

Hey everyone,

I have been trying to experiment with a browser-friendly version of this, using tools such as browserify.

Up to this point, I have been unsuccessful. Things I have tried:

• compile typescript in javascript and then create a standalone file with browserify -p esmify --standalone flashbots_old.js -o flashbots.js
• use it directly on the typescript file: browserify index.ts -p [ tsify --noImplicitAny esmify ] > bundle.js
• use it on a file that imports and exports the library.

I want to make a nice little tool for https://ethtools.odyslam.com

EDIT: After several hours, I manually edited the output bundle.js and managed to make the Flashbots objects available in window. Will update this issue when I have a working PoC. Might be interesting.

Update: Here is the source file: https://github.com/odyslam/ethtools/blob/feat/flashbots/flashbots.js

This is the addition I needed to make in order to make it work:

if (anyGlobal._FlashbotsBundleProvider == null) {
  anyGlobal._FlashbotsBundleProvider = FlashbotsBundleProvider;
  anyGlobal._FlashbotsBundleResolution = FlashbotsBundleResolution;
}

The file is the result of compiling the typescript library and then using browserify --standalone.
