Introduction

Architect is an Infrastructure as Code framework for provisioning build artifacts. Architect defines a high level manifest file in multiple open text formats which can be checked into version control. It compiles the manifest code into AWS CloudFormation and then deploys that stack. Supported formats include:

a native text file format app.arc
package.json
arc.json
arc.yaml
arc.toml

Setup

Install Architect CLI and AWS SDK

npm i -g @architect/architect aws-sdk

Check arc version.

arc version

Output:

      Version: Architect 8.5.11
 Installed to: /opt/homebrew/lib/node_modules/@architect/architect
          cwd: /Users/ajcwebdev

Initialize Project

Create a project directory and initialize a project with arc init.

mkdir ajcwebdev-architect
cd ajcwebdev-architect
arc init

Output:

     Version ⌁ Architect 8.5.11
         cwd ⌁ /Users/ajcwebdev/ajcwebdev-architect

✓ Create Your Architect project is ready! Get started with: npx arc sandbox

Running arc init in an empty directory creates a default app.arc manifest file named after that directory with one default function src/http/get-index.

Start Development Server

Architect projects work locally and offline. arc sandbox emulates most app resources defined in app.arc:

Arc App Entry Point

@app declares the application namespace in app.arc. @http defines HTTP routes in API Gateway with Lambda handler functions.

@app
ajcwebdev-architect

@http
get /

Arc Configuration

@aws defines AWS specific configuration in config.arc.

@aws
runtime nodejs12.x

Lambda Handler

index.js contains a Lambda function that returns HTML in the body.

// src/http/get-index/index.js

exports.handler = async function http (req) {
  return {
    statusCode: 200,
    headers: {
      'cache-control': 'no-cache, no-store, must-revalidate, max-age=0, s-maxage=0',

Create an About Page

Add get /about to your app.arc file and run arc init to generate a get-about directory with index.js

@app
ajcwebdev-architect

@http
get /
get /about

Alternatively you can create the directory and files yourself.

mkdir src/http/get-about
touch src/http/get-about/index.js src/http/get-about/config.arc

@aws
runtime nodejs12.x

// src/http/get-about/index.js
