Kotlin/Wasm is a new compilation target for Kotlin. You can use it in your Kotlin Multiplatform projects. With Kotlin/Wasm, you can create applications that run on different environments and devices supporting management, validation, routing, and more out of the box, and integrates with Kotlin Multiplatform projects. Visit fritz2 site for documentation, tutorials, and examples. For updates and discussions about for the JVM is now in Beta. There's now also basic support for Kotlin/Native and multiplatform projects. kapt 编译器插件与 K2 编译器的兼容性 You can use the kapt plugin in your project along with the K2 compiler

项目来说，我们建议你在 home 目录中创建 projects 目录，并将你的所有项目存放在这里。 打开终端并输入如下命令创建 projects 目录，并在 projects 目录中为 “Hello, world!” 项目创建 一个目录。 对于 Linux、macOS 和 Windows PowerShell，输入： $ mkdir ~/projects $ cd ~/projects $ mkdir hello_world hello_world $ cd hello_world 对于 Windows CMD，输入： > mkdir "%USERPROFILE%\projects" > cd /d "%USERPROFILE%\projects" > mkdir hello_world > cd hello_world 编写并运行 Rust 程序 接下来，新建一个源文件，命名为 main.rs。Rust 源文件总是以 fn main() { println!("Hello, world!"); } 示例 1-1: 一个打印 Hello, world! 的程序 保存文件，并回到当前目录为“ /projects/hello_world”的终端窗口。在 Linux 或 macOS 上， 输入如下命令，编译并运行文件： $ rustc main.rs $ ./main Hello, world! 在

where your code lives, but for this book, we’d suggest making a projects directory in your home directory and keeping all your projects there. Open a terminal and enter the following commands to make a project: Linux and Mac: $ mkdir ~/projects $ cd ~/projects $ mkdir hello_world $ cd hello_world Windows: > mkdir %USERPROFILE%\projects > cd %USERPROFILE%\projects > mkdir hello_world 15 > cd hello_world manage all of the options your project has and make it easy to share your code with other people and projects. Next, we’ll introduce you to a tool called Cargo, which will help you write real-world Rust programs

other framworks around the world, and makes develop Node.js projects faster and efficient than ever before. Using ES6/7 features to build projects is very efficent, that must be the trend. The lastest version ThinkJS, you can apply single module mode, general mode or mutiple modules mode, and to develop projects with it’s complexity range from very low to very high. By default, there are three kinds of project different environment to support different requests. You can also custom and extend them in your projects. ThinkJS supports MySQL , MongoDB and SQLite . It encapsulates many APIs of the database operations
