Deploy Contracts

In the previous article, we have finished the js contract code and ABI file, and initiated the local test node.
Now, we will deploy the contract to the environment and test the contract.

Create an account

Create config.js under the root directory and save the following code for configuring the basic information.

const config = {
    client: {
        chainId: 'cf057bbfb72640471fd910bcb67639c22df9f92470936cddc1ade0e2f2e7dc4f',
        httpEndpoint: 'http://127.0.0.1:8888',
        keyProvider: 'your keyProvider'
    },
    contract: {
        name: 'todo',
        sender: 'todo'
    },
    testContract:{
        name: 'testtodo',
        sender: 'testtodo'
    },
    account: {
        publicKey: 'your public key',
        privateKey: 'your private key'
    }
}

module.exports = config

The release of contract needs to be performed via a fibos account, so initially, we need to create a fibos account and call the method of newaccountSync() to create the contract account.

Create a new folder named scripts，and save the code to scripts/deploy.js:

const FIBOS = require('fibos.js');
const config = require('../config');
const fibosClient = FIBOS(config.client);
const fs = require('fs');

fibosClient.newaccountSync({
    creator: 'eosio',
    name: 'todo',
    owner: config.account.publicKey,
    active: config.account.publicKey,
});

Compress JS contract

We read the js contract file through the fs module and package the contract with the compileCode() method.

Save the following code to scripts/deploy.js ：

1 2	const jsCode = fs.readTextFile(`${__dirname}/../contracts/todo.js`); const wasm = fibosClient.compileCode(jsCode);

Upload JS contract

Call the setcodeSync() method to upload the compressed content to the node.

Save the following code to scripts/deploy.js ：

1	fibosClient.setcodeSync(config.contract.name, 0, 0, zipCode);

Get JS contract

Use getCodeSync() method to read js files，and it is suggested to compare the js files with the provided js contracts from projects and see whether the two are consistent with each other.

Save the following code to scripts/deploy.js ：

1 2	const code = fibosClient.getCodeSync(config.contract.name, true); console.log(code);

Upload ABI file

Obtain the ABI file using the fs module and deploy the ABI file to the node via
setabiSync()

Save the following code to scripts/deploy.js ：

1 2	const abi = JSON.parse(fs.readTextFile(`${__dirname}/../contracts/todo.abi`)); fibosClient.setabiSync(config.contract.name, abi);
