The Serverless Framework – Build applications comprised of microservices that run in response to events, auto-scale for you, and only charge you when they run. This lowers the total cost of maintaining your apps, enabling you to build more logic, faster.
The Framework uses new event-driven compute services, like AWS Lambda, Google CloudFunctions, and more. It's a command-line tool, providing scaffolding, workflow automation and best practices for developing and deploying your serverless architecture. It's also completely extensible via plugins.
Serverless is an MIT open-source project, actively maintained by a full-time, venture-backed team.

Quick Start

Watch the video guide here or follow the steps below to create and deploy your first serverless microservice in minutes.
  • Install via npm:
npm install -g serverless

  • Create a Service:
 Creates a new Serverless Service/Project serverless create --template aws-nodejs --path my-service cd my-service
  • Or Install a Service:
This is a convenience method to install a pre-made Serverless Service locally by downloading the Github repo and unzipping it. Services are listed below. serverless install -u [GITHUB URL OF SERVICE]
  • Deploy a Service:
Use this when you have made changes to your Functions, Events or Resources in serverless.yml or you simply want to deploy all changes within your Service at the same time. serverless deploy -v
  • Deploy Function:
Use this to quickly upload and overwrite your AWS Lambda code on AWS, allowing you to develop faster. serverless deploy function -f myfunction
  • Invoke a Function:
Invokes an AWS Lambda Function on AWS and returns logs. serverless invoke -f hello -l
  • Fetch Function Logs:
Open up a separate tab in your console and stream all logs for a specific Function using this command. serverless logs -f hello -t
  • Remove a Service:
Removes all Functions, Events and Resources from your AWS account. serverless remove
Check out our in-depth Serverless Framework Guide for more information.

Services (V1.0)

The following are services you can instantly install and use by running serverless install --url <service-github-url>

Note: the serverless install command will only work on V1.0 or later.

Features

  • Supports Node.js, Python, Java & Scala.
  • Manages the lifecycle of your serverless architecture (build, deploy, update, delete).
  • Safely deploy functions, events and their required resources together via provider resource managers (e.g., AWS CloudFormation).
  • Functions can be grouped ("serverless services") for easy management of code, resources & processes, across large projects & teams.
  • Minimal configuration and scaffolding.
  • Built-in support for multiple stages.
  • Optimized for CI/CD workflows.
  • Loaded with automation, optimization and best practices.
  • 100% Extensible: Extend or modify the Framework and its operations via Plugins.
  • An ecosystem of serverless services and plugins.
  • A passionate and welcoming community!

Consultants

These consultants use the Serverless Framework and can help you build your serverless projects.
Previous Serverless Version 0.5.x
Below are projects and plugins relating to version 0.5 and below. Note that these are not compatible with v1.0 but we are working diligently on updating them. Guide on building v1.0 plugins
You can read the v0.5.x documentation at readme.io.

Projects (v0.5.x)

Serverless Projects are shareable and installable. You can publish them to npm and install them via the Serverless Framework CLI by using $ serverless project install <project-name>

Plugins (v0.5.x)

Serverless is composed of Plugins. A group of default Plugins ship with the Framework, and here are some others you can add to improve/help your workflow:
  • Meta Sync - Securely sync your the variables in your project's _meta/variables across your team.
  • Hook Scripts - Easily create shell script hooks that are run whenever Serverless actions are executed.
  • CORS - Adds support for CORS (Cross-origin resource sharing).
  • Serve - Simulate API Gateway locally, so all function calls can be run via localhost.
  • Webpack - Use Webpack to optimize your Serverless Node.js Functions.
  • Serverless Client - Deploy and config a web client for your Serverless project to S3.
  • Alerting - This Plugin adds Cloudwatch Alarms with SNS notifications for your Lambda functions.
  • Optimizer - Optimizes your code for performance in Lambda. Supports coffeeify, babelify and other transforms
  • CloudFormation Validator - Adds support for validating your CloudFormation template.
  • Prune - Delete old versions of AWS lambdas from your account so that you don't exceed the code storage limit.
  • Base-Path - Sets a base path for all API Gateway endpoints in a Component.
  • Test - A Simple Integration Test Framework for Serverless.
  • SNS Subscribe - This plugin easily subscribes your lambda functions to SNS notifications.
  • JSHint - Detect errors and potential problems in your Lambda functions.
  • ESLint - Detect errors and potential problems in your Lambda functions using eslint.
  • Mocha - Enable test driven development by creating test cases when creating new functions
  • Function-Package - Package your lambdas without deploying to AWS.
  • Sentry - Automatically send errors and exceptions to Sentry.
  • Auto-Prune - Delete old AWS Lambda versions.
  • Serverless Secrets - Easily encrypt and decrypt secrets in your Serverless projects
