Go send mail Example

Requirements

This example assumes you are familiar with how serverless functions work. If needed, you can check Scaleway's official documentation.

This example uses the Scaleway Serverless Framework Plugin. Please set up your environment with the requirements stated in the Scaleway Serverless Framework Plugin before trying out the example.

Context

This example shows how to send a mail using a Serverless Function via Scaleway Go SDK.

Description

Using Serverless Compute Functions to send mails is a great way to optimise costs, manage automatic scaling and having advanced logging and metrics per Function.

Setup

Once your environment is set up, you can test your function locally with:

npm install

The code uses 3 environment variables: SCW_DEFAULT_ORGANIZATION_ID, SCW_ACCESS_KEY, SCW_SECRET_KEY. You should define them in serverless.yml or using and a .env file doc here

Deploy and run

You can deploy your function with:

serverless deploy

Then, from the given URL, you can run:

curl -v -X POST https://YOUR_FUNCTION -H "X-Auth-Token: $SCW_AUTH_TOKEN" --data '{"to": "MAILTO", "subject": "from console test", "message": "very very long msg to api"}'

After that you can check your logs in the Scaleway Console.
