You can use TypeScript to write functions in the Custom Runtime of Function Compute. This topic describes how to deploy and invoke TypeScript functions.

Prerequisites

You have installed Node.js 8.6.0 or later versions. For more information, see official download address.
Note If you have installed Funcraft, you can go to Step 2: deploy and call the function.

Step 1: Prepare the environment

An easy and simple way to install Funcraft is to download the executable binary files.

  1. Install Funcraft on the local machine. For more information, see installation instructions.
  2. Run fun --version to check whether the installation is successful.
  3. Run fun config to configure Funcraft. Then configure Account ID, Access Key ID, Access Key Secret, and Default region name as prompted. 
    $ fun config
Aliyun Account ID 1234xxx
Aliyun Access Key ID xxxx
Aliyun Access Key Secret xxxx
Default region name cn-xxxx
The timeout in seconds for each SDK client invoking 300
The maximum number of retries for each SDK client 5
Allow to anonynously report usage statistics to improve the tool over time? (Y/n)

Step 2: deploy and call the function

  1. Run the following command to clone the sample project to your local machine. 
    git clone https:// github.com/awesome-fc/fc-custom-demo
    Note If you do not have git installed, enter https://github.com/awesome-fc/fc-custom-demo in the address bar of your browser. Click the download button to download directly.
  2. Run the following command to go to the cloned sample project. 
    cd ts-demo
  3. Run the following command to deploy the project to Function Compute. 
    $ fun deploy -y
...
Waiting for service ts-demo to be deployed...
        Waiting for function fc-ts to be deployed...
                Waiting for packaging function fc-ts code...
                The function fc-ts has been packaged. A total of 336 files were compressed and the final size was 9.41 MB
        function fc-ts deploy success
service ts-demo deploy success
  4. Run the following command to invoke the deployed function. 
    $ fun invoke -e "Hello World"
...
