@kth/reqvars v2.0.1

reqvars

Check that process.env contains all the required variables!

Install

npm i @kth/reqvars

Usage

1. Write a .env.in saying which environmental variables are required in your program. This will be your specification file.

For example:

DB_HOST=localhost
DB_USER=root
DB_PASS=

If you commit the file (which is recommended) remember to leave the secrets (passwords, etc.) blank

2. As early as possible in your application, require and call check:

   require('@kth/reqvars').check()

   It will throw an error if some variable is missing

3. If you want to use another path, pass it as argument:

   require('@kth/reqvars').check('./requirements.conf')
