This package is a thin wrapper function intended to inject the value of an already-set CONTEXT environment variable into the environment variable argument given to the function.
This is best explained in https://jonsully.net/blog/configuring-environment-variables-for-all-netlify-environments/
This package is particularly well-suited for Netlify Functions, where CONTEXT is set for you. This example shows a Function that will pull the correct <CONTEXT>_API_KEY value depending on which Netlify environment it's running in:
import { contextualEnv } from 'contextual-env'
exports.handler = async _ => {
return {
statusCode: 200,
body: JSON.stringify({
status: contextualEnvVar('API_KEY'),
context: process.env.CONTEXT
})
}
}
