@netlify-tools/netlify-plugin-env v0.1.3

Netlify Plugin Env

This plugin helps to have your env variables separated by deploy context in a seamless way.

Why

It is pretty common to have multiple environments to test apps rigorously before promoting changes to production. This way, the app can be delivered with more confidence.

Netlify provides a great mechanism called deploy contexts. This mechanism allow to configure as many custom deploy contexts as you want, all you need is to add a new branch to your configuration. For instance, a branch called staging will match a deploy context called staging

That's great, isn't it? However there is a little limitation for configuring environment variables per deploy context. The only way to override an env variable for a context is through netlify.toml, which means code needs to be changed and sensitive information could be exposed.

So, this plugin aims to fix that.

Note @netlify-tools/cli can help with setting env variables by context

How it works

In order for this plugin to work properly env variables names need to have the format: [VARIABLE]_[DEPLOY-CONTEXT], so the plugin will check the process.env and will set for [VARIABLE] the value of [VARIABLE]_[DEPLOY-CONTEXT] if the current deploy context and [DEPLOY-CONTEXT] matches.

For instance:

AUTH_TOKEN=supersecret
AUTH_TOKEN_STAGING=secret@

the plugin will override the AUTH_TOKEN value with the one for AUTH_TOKEN_STAGING.

AUTH_SECRET === AUTH_TOKEN_STAGING === secret@
