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。您可以按需修改TypeScript中的示例代码实现二次开发。

前提条件

操作步骤

执行以下命令，初始化项目。
```
s init fc-custom-typescript-event -d fc-custom-typescript-event
```
说明 -d用于指定该示例项目文件夹的名称，支持自定义。
执行以下命令，进入项目目录。
```
cd fc-custom-typescript-event
```
可选：按需修改函数的示例代码，实现二次开发。

执行以下命令，部署项目。

s deploy -y

输出示例：

[2022-01-26 03:42:54] [INFO] [S-CLI] - Start the pre-action
[2022-01-26 03:42:54] [INFO] [S-CLI] - Action: s build --use-docker
[2022-01-26 03:42:55] [INFO] [FC-BUILD] - Build artifact start...
[2022-01-26 03:42:55] [INFO] [FC-BUILD] - Use docker for building.
[2022-01-26 03:42:55] [INFO] [FC-BUILD] - Build function using image: registry.regionid.aliyuncs.com/aliyunfc/runtime-custom:build-1.9.21
[2022-01-26 03:42:55] [INFO] [FC-BUILD] - skip pulling image registry.regionid.aliyuncs.com/aliyunfc/runtime-custom:build-1.9.21...
[2022-01-26 03:43:01] [INFO] [FC-BUILD] - Build artifact successfully.

Tips for next step
======================
* Invoke Event Function: s local invoke
* Invoke Http Function: s local start
* Deploy Resources: s deploy
End of method: build
[2022-01-26 03:43:01] [INFO] [S-CLI] - End the pre-action

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

helloworld:
  region:   cn-hangzhou
  service:
    name: hello-world-service
  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：

========= FC invoke Logs begin =========
FC Invoke Start RequestId: da1c9d7c-0d84-447c-8ef2-cfb97fd2****
hello
FC Invoke End RequestId: da1c9d7c-0d84-447c-8ef2-cfb97fd2****

========= FC invoke Logs end =========

FC Invoke Result:
