Step 1: Create a Procfile with the following line: web: npm run start:prod. We do this because Heroku runs npm run start by default, so we need this setting to override the default run command.
Step 2: Install the Node.js buildpack for your Heroku app by running the following command: heroku buildpacks:set https://github.com/heroku/heroku-buildpack-nodejs#v91 -a [your app name]. Make sure to replace #v91 with whatever the latest buildpack is, which you can find here.
Step 3: Add this line to your package.json file in the scripts area: "heroku-postbuild": "npm run build",. This is so Heroku can build your production assets when deploying (more of which you can read about here). Then, adjust the prebuild script in your package.json file so it looks like this: "prebuild": "npm run build:clean", to avoid having Heroku attempt to run Jest tests (which are unsupported with this buildpack).
Step 4: Run heroku config:set NPM_CONFIG_PRODUCTION=false so that Heroku can compile the NPM modules included in your devDependencies (since many of these packages are required for the build process).
Step 5: Follow the standard Heroku deploy process:
git add .git commit -m 'Made some epic changes as per usual'git push heroku master
Step 1: Run yarn to install dependencies, then npm run build to create the ./build folder.
Step 2: Navigate to AWS S3 and login (or sign up if you don't have an account). Click on Services followed by S3 in the dropdown.
Step 3: Click on Create Bucket and fill out both your Bucket Name and Region (for the USA we recommend US Standard). Click Create to create your bucket.
Step 4: Open the Permissions accordion on the right (under the Properties tab) after selecting your new bucket. Click Add more permissions, set the Grantee to Everyone (or whoever you want to be able to access the website), and give them View Permissions. Click Save.
Step 5: Click on the Static Website Hosting accordion where you should see the URL (or endpoint) of your website (ie. example.s3-website-us-east-1.amazonaws.com). Click Enable website hosting and fill in both the Index document and Error document input fields with index.html. Click Save.
Step 6: Click on your new S3 bucket on the left to open the bucket. Click Upload and select all the files within your ./build folder. Click Start Upload. Once the files are done, select all of the files, right-click on the selected files (or click on the Actions button) and select Make Public.
Step 7: Click on the Properties tab, open Static Website Hosting, and click on the Endpoint link. The app should be running on that URL.
