* NodeJS has built-in testing tools now, so no need to include Mocha/Chai which bring in a lot of transitive dependencies. * Removes ethers, as it was only being used for a few utility functions (which are now in `utils.js` and `keccak256`, whiche is better sourced from @noble/hashes. * Adds @noble/hashes for `keccak256`. * Removes hardhat, since it was brought in only to test one thing, and it is huge. * Switches to esbuild for simple ESM targeted bundling with inlnined NodeJS dependencies. * Pinned all JS dependencies to fixed versions. * Adds a Dockerfile for generating reproducible builds. * Commented out two tests that had a dependency on Hardhat.

Fork
This is a fork of the version of circomlibjs that is used in the Tornado Classic UI. The changes here only seek to remove as many dependencies as possible, and make the project bundlable with a simple bundler like esbuild. A Dockerfile is included to facilitate deterministic builds of the generated build/bundle.mjs file. You can generate and extract the bundle file by doing:
docker image build --tag temp_image .
docker container create --tag temp_container temp_image
docker container temp_container:/workspace/build/bundle.mjs bundle.mjs
docker container rm temp_container
docker image rm temp_image

Note: This was forked off of a more recent version of circomlibjs, if you want to see only the changes between the latest version of circomlibjs and this then see bfa4ce1366...MicahZoltu:circomlibjs:main

This library is used to make tests of circomlib circuits.
In the src directory the package includes these programs.
In the test directory includes its own tests and.
In the tools directory includes programs to precompute some needed parameters.
