Etherlime, Truffle, Quorum, Web3.js Slither — all with updates
Blockchain Dev Weekly Digest 08.04.19
Ladies and Gents of the blockchain building community — this week it’s been a pretty hard build for all the tools and libraries.
Over the last week we’ve seen noteworthy updates by most of the buidl game players — Etherlime, Truffle, Web3js, Quorum, Slither and more. So without any further ado, let me tell you more about what’s been cooking in the development space.
Languages, Tools and Libraries updates
Etherlime 1.1.0
Resources: https://medium.com/limechain/etherlime-spring-updates-7f924f1a605e
The Etherlime team has released a new version, full with major improvements and integrations. Here is list of the things included in this release:
etherlime coverage
Due to the ineffective way solcover is measuring and calculating the coverage of smart contracts, a lot of developers were having troubles and inaccuracies when using the etherlime coverage. Etherlime coverage is now completely remade and is integrated with the 0x coverage tool. All the things you expect from it, cool coverage report and html version, are now available when running the etherlime command.
etherlime zk
Etherlime has integrated with the iden3 snarkjs library in order to support the efforts developing zk apps. Through the etherlime cli one can initialise etherlime project with zk inited and start compiling and generating circuits. After circuits one can generate proofs, verifier scripts and smart contracts and deploy them on the network.
etherlime flattener
Etherlime now has a flattener command — etherlime flatten . Through its use, etherlime can now generate you a flattened file with your contracts and dependancies.
etherlime ide
Integrated Development Environment comes with etherlime out of the box. You can now easily get into coding smart contracts by opening their project through etherlime ide.
vyper compiler
Vyper is growing more and more popular as an Ethereum smart contract language. Etherlime now supports a compilation of vyper smart contracts. You just need to run a docker demon and name your vyper files with .vy and you are good to go!
react shape
A new shape for React was created and allows you to start your dapp projects with this popular framework.
