HelloWorldcontract address 0xa807685dd3cf6374ee56963d3d95065f6f056372 HelloWorld deploy success! 调用合约 编写合约调用程序 用nodejs实现，具体实现方法请直接看demoHelloWorld.js源码。 # 进入合约所在目录 cd /mydata/FISCO-BCOS/FISCO-BCOS/tools/contract vim 'dist/conf' } } } 总结 SDK应用开发步骤总结 根据以上描述，使用web3sdk开发区块链应用主要包括如下过程： 1. 根据应用功能设计合约数据结构和接口; 2. 编写智能合约，可先用Nodejs简单验证合约代码逻辑是否正确，验证 通过后，将合约代码转换成java代码 3. 编写java应用，调用合约java接口完成合约部署和调用功能 4. 配置并编译java应用 5. 应用功能测试 #节点0的目录 ├── node1 #节点1的目录 ├── nodejs #nodejs相关安装目录 ├── node_manager.sh #节点管理脚本 ├── node.sh #nodejs相关环境变量 ├── register.sh #注册节点入网脚本, 扩容使用 ├── start.sh

Target Idris is capable of producing JavaScript code that can be run in a browser as well as in the NodeJS environment or alike. One can use the FFI to communicate with the JavaScript ecosystem. 13.7.1 Code resulting file can be embedded into your HTML just like any other JavaScript code. Generating code for NodeJS is slightly different. Idris outputs a JavaScript file that can be directly executed via node. $ will automatically add a newline to the end of each string. This behaviour does not show up in the NodeJS code generator. 13.7.2 Using the FFI To write a useful application we need to communicate with

Overview ... “Node's goal is to provide an easy way to build scalable network programs.” http://nodejs.org/#about A full programming environment, not just for building “servers” “The official name of Global, JSON, Math, Number, Object, RegExp, String 2.

convenient ones. Official packages for all the major platforms are available at https://nodejs.org/en/download/. There you can choose to download an LTS version (LTS stands for Long Term Support) brew install node Other package managers for Linux and Windows are listed in https://nodejs.org/en/download/package-manager/ nvm is a popular way to run Node. It allows you to easily switch in the browser we use ES Modules, a standard that's recently landed in Node.js as well (https://nodejs.org/api/esm.html) Going forward ES Modules ( import ) are the way to load modules across all JavaScript
