Namecheap

Prerequisites

Sign up for a domain on Namecheap
Deploy an app with Architect and make note of the staging and production URLs
Make sure your app is deployed to us-east-1
Ensure the @app name is uniquely named after the domain.

In this step we will request a certificate from Amazon for our domain.

Open up AWS Certificate Manager in the AWS Console in us-east-1 (region is required!)
Click Request a certificate and then Request a public certificate
Ensure example.com and *.example.com for sub domains to work
Choose DNS validation and click Next
Add any tags and confirm the request
Open up Namecheap account dashboard and click Manage for the particular domain you want to use.
Open the Advanced DNS tab.
Click ADD A NEW RECORD
Create CNAME records of both issued certificates
Wait until they change from pending to success

Generate a CloudFront distribution with the certificate from step 1.

Sign into AWS CloudFront in the AWS Console
Click Create Distribution and then click Get Started
Open API Gateway and make note of the Invoke URL.
Enter the URL from API Gateway in Origin Domain Name
Set Origin Protocol Policy to Match Viewer
Add the Alternate Domain Names (CNAMEs) that you will be using. ex. example.com.
Set Viewer Protocol Policy to Redirect HTTP to HTTPS
Set Allowed HTTP Methods to GET, HEAD, OPTIONS, PUT, POST, PATCH, DELETE
Set Compress Objects Automatically to Yes
Set SSL Certificate to Custom SSL Certificate and select the cert from step 1
Click Create Distribution
Repeat for staging domain.

Add Alias and CNAME records to DNS.

Open up Namecheap account dashboard and click Manage for the particular domain you want to use.
Open the Advanced DNS tab.
Click ADD A NEW RECORD
Use record type Alias for the root domain.
- Add @ in the Host input and add the CloudFront domain that was created in step 2 to the Value input.
Use record type CNAME for the staging domain.
- Add the word staging to the Host input and add the CloudFront domain that was created in step 2 to the Value input.

Now we’re done! You can check to see if your domains are online with the DNS checker tool DNS Checker tool.
