Before we build and publish our app, we should free up some memory on the Cloud9 instance. If you’re using a micro Cloud9 instance size, there’s a good chance there won’t be enough memory available to keep our development web server running and to create a production build.
Go to the terminal tab that’s running the development webserver (where you ran npm start)
Press Control-C to interrupt the development webserver and kill it.
The AWS Amplify CLI makes it easy to deploy our app to a publicly accessible bucket on S3.
amplify hosting add, select a deployment mode (for this workshop, select ‘Development’), and respond to the questions (you can accept the default value of index.html for the index and error doc).
$ amplify hosting add ? Select the environment setup: DEV (S3 only with HTTP) ? hosting bucket name photoalbums-19700101010203--hostingbucket ? index doc for the website index.html ? error doc for the website index.html
Wait for the new S3 bucket that will serve our app’s static content is created. This usually takes about a minute.
Wait while Amplify builds a production version of our app and deploys it to the hosting bucket. This process usually takes a minute or two.
After the build and deploy finishes, you’ll see a URL for the version of deployed app. Any time you make new changes to the app, just re-run
amplify publish whenever you want to push a new build out.
