Using environment variables with HCS
Environment Variables
A guide how to use environment variables in HCS
You can define environment variables for your resources, and they will be available in your application.
Preview Deployments could have different environment variables, so you can test your application as a staging environment for example.
Build Time Variables
If you would like to set environment variables for the build process, you can do by setting Build Variable
on the UI.
You could have 3 types of shared variables:
Team Based
Project Based
Environment Based (production, staging, etc.)
You can set shared variables on their respective pages.
Then you can use these variables anywhere. For example: You defined NODE_ENV
to production
.
Team Based
You can set them on the Team
page and use it with {{team.NODE_ENV}}
.
Project Based
You can set them on the Projects
page, under the gear icon and use it with {{project.NODE_ENV}}
.
Environment Based
You can set them on the Environments
page (select a Project
), under the gear icon and use it with {{environment.NODE_ENV}}
.
