Ethereum Cookbook

Getting ready

Make sure that you have web3.js available in your application to run these scripts. You will also need to install solc.js in order to compile your contract. You can install solc.js using npm:

npm install solc --save

Every transaction has to mine before you can see the result of the execution. In the Ethereum main or test networks, there are other miners to take care of this. If you are using a private network, you can start and stop the mining process from the web3 JavaScript console using the following commands:

miner.start() // starts miningminer.stop() // Stops mining
