envmanager v1.1.3

envmanager

envManager is a npm module that allow you to specify, validate and check local environmental variables. It works best with dotenv as it was created for that.

Install

npm install envmanager --save

Usage

To use envmanager, you must create a file called .env_template on your root directory. This will allow envmanager to generate and test your env file. Your .env_template should just include each variable you would like to include in your .env such as:

database_uri
password
username

To add defaults for your .env, do the following

password=actualpassword

After your .env_template has been configured, you should run node ./node_modules/envmanager/envmanager.js generateEnv to generate your environment. For best practices for your developers, you should insert that command into your package.json as the following:

...
"scripts": {
  "env": "node ./node_modules/envmanager/generateEnv.js"
},
...

and run the program as npm run env.

In your program, as early as you can, usually just in your index.js, add the following code:

const envManager = require("envmanager");
const manager = new envManager();

if(manager.checkVariables()){
  // the rest of your code
}

Note, as of now the envmanager will throw an exception ending your program if variables are not properly assigned.

Testing

npm test

FAQ

Why did you make this program?

This system was originally built for HackMerced to allow student developers to easily get started on contributing to our projects.

Should I commit the .env file?

Please don't, add it to your .gitignore, otherwise people will get to it!
