We're happy to release v1.4.0 of the Serverless Framework today!
This release is packed with lots of great new features. Let's take a look at the highlights!
Here are the highlights of this release. You can find a complete list of all the updates in the changelog.
v1.4 introduces a new event
alexaSkill event source.
You can now hook up your Lambdas with
alexaSkill events like this:
functions: hello: handler: handler.hello events: - alexaSkill
AWS introduced .NET core support for Lambda at re:Invent.
Serverless has you covered and ships with the new
aws-csharp template. You can use it to create C# services on AWS Lambda.
serverless create --template aws-csharp
to create a new C# service.
The C# "hello world" example will show you how you can setup and deploy your C# service.
serverless install command makes it possible for you to download services based on GitHub repository URLs. The downside was that only full repositories could be downloaded.
Until now! A recent enhancement makes it possible to download specific directories from a GitHub URL.
Want to play around with the REST API example which connects to a DynamoDB?
Just install the service with the following command:
serverless install --url https://github.com/serverless/examples/tree/master/aws-node-rest-api-with-dynamodb
v1.3 introduced service metrics support allowing you to get function metrics by running:
serverless metrics --function hello
v1.4 enhances this command so that you can get service-wide metrics (all functions combined) when you run:
serverless invoke and its local equivalent
serverless invoke local are a great way to invoke your function to test its behavior.
v1.4 now supports stdin so that you can pipe data directly into the
serverless invoke call like this:
echo "hello world!" | serverless invoke --function hello --stage dev --region us-east-1
This provides way more flexibility to invoke a function with different data. Here's an example of how a
dataGenerator.js file could be used to generate data for your function:
node dataGenerator.js | serverless invoke local --function hello
As usual we've also pushed a bunch of enhacements, refactorings and bug fixes (thanks for reporting!) in this release.
The Serverless Examples Repository is an excellent resource if you want to explore some real world examples and learn more about what Serverless architectures look like.
Note that we're using strict Semver for our Serverless Framework versioning. This way you'll know when we introduce major features or breaking changes.
