TypeScript - 函数计算

通过函数计算的Custom Runtime，您可以使用TypeScript在函数计算平台编写函数。本文介绍快速部署和调用TypeScript函数的详细步骤。您可以修改TypeScript中的示例代码实现二次开发，满足您的需求。

前提条件

您已完成以下操作：

操作步骤

在目标目录中，执行以下命令，初始化项目。
```
s init start-fc-custom-samples -d start-fc-custom-samples
```

执行以下命令，进入code目录内。

cd start-fc-custom-samples/typescript/event-demo/code

执行以下命令，安装依赖。

npm install

输出示例：

npm WARN old lockfile
npm WARN old lockfile The package-lock.json file was created with an old version of npm,
npm WARN old lockfile so supplemental metadata must be fetched from the registry.
npm WARN old lockfile
npm WARN old lockfile This is a one-time fix-up, please be patient...
npm WARN old lockfile

执行以下命令，进入项目目录。
```
cd ../
```

执行以下命令，部署项目。

s deploy -y

输出示例：

Tips for next step
======================
* Display information of the deployed resource: s info
* Display metrics: s metrics
* Display logs: s logs
* Invoke remote function: s invoke
* Remove Service: s remove service
* Remove Function: s remove function
* Remove Trigger: s remove trigger
* Remove CustomDomain: s remove domain



fc-ts-demo-fc-ts:
  region: cn-hangzhou
  service:
    name: custom-demo
  function:
    name: tsEventFunc
    runtime: custom
    handler: index.handler
    memorySize: 512
    timeout: 3

执行以下命令，远程调用函数。

s invoke -e "hello"

输出示例：

[2021-09-09T16:33:36.971] [INFO ] [S-CLI] - Start ...
========= FC invoke Logs begin =========
