gatsby_Gatsby CLI快速参考

gatsby

When working with Gatsby.js, we constantly make use of its built-in command line interface (CLI.) This essential tool allows us to do things like creating new projects from starters, launching a dev server with hot-reloading, and generating production builds. Here’s a quick reference guide to help you use it like a pro!

使用Gatsby.js时 ，我们会不断使用其内置的命令行界面 (CLI)。此基本工具使我们能够执行诸如从启动程序创建新项目，通过热重装启动开发服务器以及生成生产等工作。建立。 这是一个快速参考指南，可帮助您像专业人士一样使用它！

安装 (Installation)

If you haven’t already performed a global installation of gatsby-cli, you will need to do that first:

如果尚未执行gatsby-cli的全局安装，则需要首先执行以下操作：

$ npm install -g gatsby-cli

With gatsby-cli installed globally, you can now run all of Gatsby’s commands from anywhere on your machine. Now let’s cover the available commands!

全局安装gatsby-cli ，您现在可以在计算机上的任何位置运行Gatsby的所有命令。 现在，让我们介绍可用的命令！

创建一个新项目 (Create a New Project)

The new command creates a new Gatsby site, installs all of its dependencies, and initializes a new git repository locally with an initial commit.

new命令创建一个新的Gatsby站点，安装其所有依赖项，并使用初始提交在本地初始化新的git存储库。

Running the command with no arguments will prompt for a folder name and optional starter:

$ gatsby new

可用参数： (Available Arguments:)

  site directory ：可选，指定安装目录。

• starter: Optional, this can either be a repo URL or a Github username/repo string. If this is not set, gatsby-starter-default is automatically used.

  starter ：可选，可以是回购URL或Github用户名/回购字符串。 如果未设置，则自动使用gatsby-starter-default 。

Here’s an example that installs into a my-site folder, and uses gatsby-starter-blog as the starter:

这是一个示例，该示例安装到my-site文件夹中，并使用gatsby-starter-blog作为启动器：

$ gatsby new my-site gatsbyjs/gatsby-starter-blog

The build command compiles your site for production-ready deployments.

build命令编译您的站点以进行生产就绪部署。

$ gatsby build

可用选项： (Available Options:)

• -prefix-paths: Builds the site with link paths prefixed. (But only if you’ve set pathPrefix in your Gatsby config!)

服务本地生产 (Serve Production Builds Locally)

The serve command runs production builds locally, which can be helpful for testing and debugging. (You must run the build command prior to running this, of course.)

serve命令在本地运行生产版本，这有助于测试和调试。 (当然，您必须在运行此命令之前先运行build命令。)

$ gatsby serve

Here’s an an example that serves a production build at http://10.0.0.1:9999 with prefixed paths, and automatically opens in a browser:

这是一个示例，该示例使用带有前缀路径的http://10.0.0.1:9999提供产品版本，并在浏览器中自动打开：

删除过时的缓存/构建 (Remove Stale Caches/Builds)

The clean command deletes the .cache and public directories from your project root.

clean命令从项目根目录删除.cache和public目录。

$ gatsby clean

While this command is probably not something you will use too often, it’s still a handy shortcut to know about! Sometimes strange caching issues happen, and this is a fast and safe way to clear it. (It’s easier to type two words vs. typing out two folder deletion commands, and there’s no risk of accidentally deleting the wrong folder.)

尽管您可能不会经常使用此命令，但是它仍然是一个方便的快捷方式！ 有时会发生奇怪的缓存问题，这是一种快速安全的清除方法。 (键入两个单词比键入两个文件夹删除命令更容易，而且不存在意外删除错误文件夹的风险。)

The repl command opens access to Gatsby’s interactive REPL (Read-Eval-Print-Loop) shell.

repl命令打开对Gatsby的交互式REPL( Read-Eval-Print-Loop )Shell的访问。
