Add Custom Variables
By default, this template comes with one predefined environment variable called BACKEND_ENDPOINT. This variable can be used in the ReactJS application with window.env.BACKEND_ENDPOINT.
You can also add more custom environment variables by following the steps below. In this example we will add a new variable called MyCustomVar.
- Update the input properties in the ./.microtica/schema.json file by adding the new variable of type string.
- Update the CloudFormation template by adding the new variable as parameter and then reference the parameter in the DeploymentCustom resource properties.
- The last step is to update the logic that provides the environment variable in your web application. This code stores a /env.js file that assigns all environment variables under window.env. The new variable can be used with window.env.MyCustomVar.
- At the end, please check if you have the /env.js file imported in the public/index.html file.
- Commit and push your changes. Automated build and deploy should start, once the deployment is done, go to Website resource settings, enter the value of the new environment variable
