Gatsby - How to set ENABLE_GATSBY_REFRESH_ENDPOINT to true

To enable /__refresh end point, I have to set ENABLE_GATSBY_REFRESH_ENDPOINT to true, but I don't know how to add environment variables to gatsby. How can I do that?

Solution

  • In the root of your project, you'll want to create a .env.development file if you don't have one already and add the following:

    ENABLE_GATSBY_REFRESH_ENDPOINT=true

    You will also want to add that file to your project's .gitignore, it's good practice to not commit .env files to source control. Gatsby outlines how to use environment variables here.
