( Log Out /  Those modules typically involve simple API usage, as it is often difficult to write client-side JavaScript examples without them. JSON is a format that returns data from server to browser. Before we do this we need some EVM code to pass to the transaction.

API stands for Application Program Interface, which can be defined as a set of methods of communication between various software components. You can also use web3.eth.serpent() to compile serpent code in the same way. We will test it directly in the browser by sending a negative test comment. We will try to keep things simple, so to work with queries we will use the axios library because of its simplicity and universality. Click approve and you should see a transaction appear in the ‘pending’ pane if this has worked correctly. Each object represents a function of the contract and is made up of very specific attribute-value pairs. Change ). in the last example shouldn’t it be: “contract.sendCoin(receiverAddress, amount);”, instead of “contract.send(receiverAddress, amount);” API acts as a layer between your application and external service.
