Jul 6, 2017

Today we're happy to announce the new Serverless Framework v1.17 release!

F# service template

With Serverless v1.17 you can now create and deploy F# service templates to AWS.

You can bootstrap your new F# service with the help of the serverless create --template command:

serverless create --template aws-fsharp --path my-fsharp-service

Next up you need to build the project:

cd my-fsharp-service


After that you're ready to deploy and invoke your first F# function:

serverless deploy

serverless invoke --function hello

The F# service template supports all the configs and event sources you can find in our AWS documentation.

Skip deployment if files not changed

Starting now, Serverless will automatically compare your current service files on disk to the remotely uploaded service files of your last deployment.

A re-deployment is only triggered if at least one of the files are different.

This feature is enabled by default and works for the serverless deploy and the serverless deploy function commands.

However you can still force a deployment by specifying the --force option like this:

serverless deploy --force


serverless deploy function --function func1 --force
