如何使用 Serverless Framework 的 Express Component 快速创建文本翻译工具呢？跟着下面的步骤一起来试试吧！

\n

1. 安装

\n

通过 npm 安装最新版本的 Serverless Framework

\n
$ npm install -g serverless
\n

2. 创建

\n

创建并进入一个全新目录：

\n
$ mkdir express-trans && cd express-trans
\n

通过如下命令和模板链接，快速创建该应用：

\n
$ serverless create --template-url https://github.com/tinafangkunding/serverless-translate\n$ cd serverless-translate
\n

进入 src 目录，执行如下命令，安装对应依赖

\n
cd src && npm install
\n

3. 配置

\n

修改模板中的 .env.example 为 .env，并在 API 密钥管理中获取并配置腾讯云的 SecretId 和 SecretKey 秘钥信息。

\n
# .env\nTENCENT_SECRET_ID=123\nTENCENT_SECRET_KEY=123
\n

您可以 登陆 https://cloud.tencent.com/login 或注册 https://cloud.tencent.com/register 腾讯云账号。

\n

4. 部署

\n

在 serverless.yml 文件下的目录中运行如下命令部署应用

\n
$ serverless deploy
\n

部署完毕后，你可以在命令行的输出中查看到该应用的 URL 地址，访问地址即可查看部署结果。支持的翻译语言类型参考 接口文档。

5. 监控

\n

在 Serverless Dashboard 中查看应用级别的监控信息。当前支持展示如下监控指标：

\n\n

6. 移除

\n

在 serverless.yml 文件所在的目录下，通过以下命令移除部署的 Express 服务。移除后该组件会对应删除云上部署时所创建的所有相关资源。

\n
$ serverless remove
\n
