Deploy ReactJS App with S3 Static Hosting

Create a simple react app. Configure an S3 bucket for static web hosting. Deploy! Prerequisites: AWS Account created AWS IAM User AWS CLI installed (and additional dependencies) AWS Credentials Locally SetupOn the IAM console, we need to create a user for the Serverless Framework. Giving the Serverless Framework permission to create, update, and delete resources on AWS. Click Add user.

Give the user the name serverless-admin with Programmatic access selected. Click Next: Permissions.

 

 

 Switch to the Attach existing policies directly tab and select AdministratorAccess (for testing). In the future, make sure to scope the IAM permissions based on your level of access. As this is not a deep dive into IAM we will keep it simple. Then click Next: Review.

 We need to copy the Access Key ID and the Secret Access Key for later use. So click Download .csv. Click Close.

 

now, download latest aws cli https://docs.aws.amazon.com/cli/latest/userguide/install-cliv2-linux.html 

after it is installed run 

./install awscli

 replace credentials by yours

create now the bucket where the app is going to be hosted

after the bucket is created 

In the Set properties tab, you can just hit next.

 

click on Static web hosting and set it like this

 

 

 

 

On the Set permissions tab, select Grant public read access to this bucket and hit next.

 

 

 

 

Now that our S3 bucket is set up for Static Hosting we need to set up permissions. To do this click the Permissions tab and select Bucket Policy. You can copy and paste what I have below, swapping out example-bucket with your bucket name.

 

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "AllowPublicReadAccess",
      "Effect": "Allow",
      "Principal": "*",
      "Action": [
        "s3:GetObject"
      ],
      "Resource": [
        "arn:aws:s3:::example-bucket/*"
      ]
    }
  ]
}

This gives users read access to your bucket. Go ahead and hit save. 

 

Let’s open up our react-app project in a text editor and create a deployment script to make updating our live ReactJS application easier.

Open up your package.json file. Inside there is a section called scripts. We’re going to add a script called deploy which will use the AWS CLI to sync our build directory to our S3 bucket. Swap out example-bucket for your bucket name and copy/paste it into your package.json file using the image below as a guide.

 

aws s3 sync build/ s3://example-bucket --acl public-read

 now to compile do it as usually as npm run build

 and to deploy do npm run deploy

 so, let's get now the public Endpoint in the S3 - PROPERTIES - STATIC WEB HOSTING

 in this case the

Endpoint : http://fitomillonario.s3-website-us-east-1.amazonaws.com
