Serverless-http: Use Your Existing Middleware Framework in AWS Lambda

serverless-http

Examples

Please check the examples folder!

Usage example using the Koa framework

const serverless = require('serverless-http');
const Koa = require('koa'); // or any supported framework

const app = new Koa();

app.use(/* register your middleware as normal */);

// this is it!
module.exports.handler = serverless(app);

// or as a promise
const handler = serverless(app);
module.exports.handler = async (event, context) => {
  // you can do other things here
  const result = await handler(event, context);
  // and here
  return result;
};

Usage example using the Express framework with Azure

const serverless = require('serverless-http');
const express = require('express');

const app = express();

app.use(/* register your middleware as normal */);

const handler = serverless(app, { provider: 'azure' });
module.exports.funcName = async (context, req) => {
  context.res = await handler(context, req);
}

Limitations

Your code is running in a serverless environment. You cannot rely on your server being 'up' in the sense that you can/should not use in-memory sessions, web sockets, etc. You are also subject to provider specific restrictions on request/response size, duration, etc.

Think of this as a familiar way of expressing your app logic, not trying to make serverless do something it cannot.

Contributing

Pull requests are welcome! Especially test scenarios for different situations and configurations.

Further Reading

Here are some more detailed examples and advanced configuration options as well as provider-specific documentation

Description

This module allows you to 'wrap' your API for serverless use. No HTTP server, no ports or sockets. Just your code in the same execution pipeline you are already familiar with.

Pdf2gerb: Perl Script Converts PDF Files to Gerber format

pdf2gerb

Perl script converts PDF files to Gerber format

Pdf2Gerb generates Gerber 274X photoplotting and Excellon drill files from PDFs of a PCB. Up to three PDFs are used: the top copper layer, the bottom copper layer (for 2-sided PCBs), and an optional silk screen layer. The PDFs can be created directly from any PDF drawing software, or a PDF print driver can be used to capture the Print output if the drawing software does not directly support output to PDF.

The general workflow is as follows:

1. Design the PCB using your favorite CAD or drawing software.
2. Print the top and bottom copper and top silk screen layers to a PDF file.
3. Run Pdf2Gerb on the PDFs to create Gerber and Excellon files.
4. Use a Gerber viewer to double-check the output against the original PCB design.
5. Make adjustments as needed.
6. Submit the files to a PCB manufacturer.

Please note that Pdf2Gerb does NOT perform DRC (Design Rule Checks), as these will vary according to individual PCB manufacturer conventions and capabilities. Also note that Pdf2Gerb is not perfect, so the output files must always be checked before submitting them. As of version 1.6, Pdf2Gerb supports most PCB elements, such as round and square pads, round holes, traces, SMD pads, ground planes, no-fill areas, and panelization. However, because it interprets the graphical output of a Print function, there are limitations in what it can recognize (or there may be bugs).

See docs/Pdf2Gerb.pdf for install/setup, config, usage, and other info.

Serverless Express – Easy APIs On AWS Lambda & AWS HTTP API

TLDR - Take existing Express.js apps and host them easily onto cheap, auto-scaling, serverless infrastructure on AWS Lambda and AWS HTTP API with Serverless Express. It’s packed loads of production-ready features, like custom domains, SSL certificates, canary deployments, and costs ~$0.000003 per request.

If you simply want to host a common Express.js Node.js application, have it auto-scale to billions of requests, and charge you only when it’s used, we have something special for you…

Announcing Serverless Express, a Serverless Framework offering enabling you to easily host and manage Express.js applications on AWS Lambda and the new AWS HTTP API, which is 60% faster and 71% cheaper than their initial API Gateway product.

Serverless Expess is a pure Express.js experience and it’s perfect for those that want to focus on apps, not infrastructure complexity.

Here are the highlights:

• Easy, Safe, Performance - Includes the optimal infrastructure pattern for cost, performance & scale.
• Never Pay For Idle - No API requests? No cost. Averages ~$0.000003 per request.
• Zero Configuration - Add your Express app, then deploy (advanced config options are available).
• Fast Deployments - Deploy changes to the cloud in seconds.
• Real-time Logging - Rapidly develop on the cloud w/ real-time logs and errors in the CLI.
• Canary Deployments - Deploy your app gradually to a subset of your traffic.
• Custom Domain + SSL - Auto-configure a custom domain w/ a free AWS ACM SSL certificate.
• Team Collaboration - Collaborate with your teamates with shared state and outputs.

Here is how to get started and deliver a Serverless Express.js based API with a custom domain, free SSL certificate and much more! You can also check out our Serverless Fullstack Application boilerplate, which includes Serverless Express in a real-world example that features a database, website using React and more.

Set-Up

Serverless Express is a Serverless Framework Component (i.e premium experiences for popular serverless use-cases) and you’ll need to install Node.js and the Serverless Framework CLI to use it.

Install Node.js here.

Then run this command to install Serverless Framework.

npm i -g serverless

Next, install the Serverless Express template:

serverless create --template-url https://github.com/serverless/components/tree/master/templates/express

Lastly, Serverless Express deploys onto your own Amazon Web Services account, so you’ll need Access Keys to an AWS account you own. Follow this guide to create those.

After you have created AWS Access Keys you can add them directly to an .env file, or reference an AWS Profile in a .env file, within the root of the template you installed.

AWS_ACCESS_KEY_ID=123456789
AWS_SECRET_ACCESS_KEY=123456789

You can also reference an AWS Profile in a .env file like this.

AWS_PROFILE=default

If you don’t include a .env file, the Serverless Framework will automatically look for a default AWS Profile in the root folder of your machine.

Also, Serverless Framework has a built-in stages concept. If you change the stage it will deploy a totally separate copy of your serverless application.

# serverless.yml
component: express@1.0.8
  name: express-api
  stage: prod

Even better, you can use different .env files for each stage by simply using this convention:

.env # all stages
.env.dev # "dev" stage
.env.prod # "prod" stage

One last—often overlooked—step is to install the Express.js dependency, by running npm i in the template.

Serverless Framework: Use AWS S3 Object Lambda to Resize Images on The Fly

Goal

In this post, I will show you how to use Amazon S3 Object Lambda to resize images on the fly. The  Serverless Framework will be used to define the Infrastructure as Code and to simplify the deployment. Sharp will be used to resize the images. Lambda will be written using the Node.js 14x  Lambda runtime

What’s Amazon S3 Object Lambda

One of the most common Lambda patterns is to transform data stored inside Amazon S3. Generally, a lambda function is invoked after a file has been uploaded. Lambda would retrieve that file, apply any needed transformation (e.g. converting type of file) and store the result in S3.

That pattern was working well, however, it would require some work done onto a file despite that being accessed in the future or not.

If you needed to convert a file on the fly you should have created a Lambda function, invoke it via Amazon API GW and wait for the lambda to perform the transformation.

AWS has recently introduced  Amazon S3 Object Lambda in a good post by Danilo Poccia. S3 Object Lambda allows creating a Lambda directly connected to the S3 bucket (using  S3 Access Points) that is automatically invoked when retrieving the object from S3!

That means that our application needs only to send an S3 Get Object request to retrieve the original or transformed data

Also, a very important peculiarity of using Amazon S3 Object Lambda it’s that the file you want to retrieve doesn’t need to exist on S3! We will make use of this for our scenario

_Note: High-level AWS CLI S3 commands (e.g. _aws s3 cp_) don’t currently support S3 Object Lambda, instead we need to use low-level S3 API commands (e.g. __aws s3api get-object)_

Common Use Cases

In his post, Danilo highlighted the most common use cases for Amazon S3 Object Lambda:

• Converting across data formats (e.g. XML to JSON)
• Compressing or decompressing files on the fly
• Resizing images on the fly (our use case!)
• Many more (left to the devs’ creativity)

Serverless Plugin for Microservice Code Management and Deployment

Serverless M

Serverless M (or Serverless Modular) is a plugin for the serverless framework. This plugins helps you in managing multiple serverless projects with a single serverless.yml file. This plugin gives you a super charged CLI options that you can use to create new features, build them in a single file and deploy them all in parallel

Currently this plugin is tested for the below stack only

• AWS
• NodeJS λ
• Rest API (You can use other events as well)

Prerequisites

Make sure you have the serverless CLI installed

# Install serverless globally
$ npm install serverless -g

Getting Started

To start the serverless modular project locally you can either start with es5 or es6 templates or add it as a plugin

ES6 Template install

# Step 1. Download the template
$ sls create --template-url https://github.com/aa2kb/serverless-modular/tree/master/template/modular-es6 --path myModularService

# Step 2. Change directory
$ cd myModularService

# Step 3. Create a package.json file
$ npm init

# Step 3. Install dependencies
$ npm i serverless-modular serverless-webpack webpack --save-dev

ES5 Template install

# Step 1. Download the template
$ sls create --template-url https://github.com/aa2kb/serverless-modular/tree/master/template/modular-es5 --path myModularService

# Step 2. Change directory
$ cd myModularService

# Step 3. Create a package.json file
$ npm init

# Step 3. Install dependencies
$ npm i serverless-modular --save-dev

If you dont want to use the templates above you can just add in your existing project

Adding it as plugin

plugins:
  - serverless-modular

Now you are all done to start building your serverless modular functions

API Reference

The serverless CLI can be accessed by

# Serverless Modular CLI
$ serverless modular

# shorthand
$ sls m

Serverless Modular CLI is based on 4 main commands

• sls m init
• sls m feature
• sls m function
• sls m build
• sls m deploy

init command

sls m init

The serverless init command helps in creating a basic .gitignore that is useful for serverless modular.

The basic .gitignore for serverless modular looks like this

#node_modules
node_modules

#sm main functions
sm.functions.yml

#serverless file generated by build
src/**/serverless.yml

#main serverless directories generated for sls deploy
.serverless

#feature serverless directories generated sls deploy
src/**/.serverless

#serverless logs file generated for main sls deploy
.sm.log

#serverless logs file generated for feature sls deploy
src/**/.sm.log

#Webpack config copied in each feature
src/**/webpack.config.js
