netlify-plugin-redirect-env-placeholders

This plugin replaces the placeholders defined in _redirects file dynamically on preBuild stage.

What it does

Imagine you have a file for your redirects defined in _redirects file:

/api/checkout/* {{env:TEST_API_URL}}/:splat 200

/api/auth/* {{env:ENV_NON_EXISTENT|http://default-domain.com}}/api/auth/:splat 200

And you defined TEST_API_URL environment variable to be https://this.is.test/hey

With this plugin, your published _redirects will be transformed to:

/api/checkout/* https://this.is.test/hey/:splat 200

/api/auth/* http://default-domain.com/api/auth/:splat 200

How to use

Syntax

{{env:ENV_VAR_NAME}} or {{env:ENV_VAR_NAME|default_value}} (if the variable does not exist, default_value will be written)

netlify.toml

[[plugins]]
package = "netlify-plugin-redirect-env-placeholders"
  [plugins.inputs]
  source = '_redirects'
  base = '/opt/build/repo/'

Both inputs are optional:

name	description	default
source	Source filename (It should be on the root path of your project)	_redirects
base	Base path of the build during preBuild step where files exist	.

Note

If you would like to use this plugin with netlify-plugin-contextual-env, please make sure that this plugin is added afterwards.
