Welcome, How to Manage Secrets & Configs using .DOTENV in NodeJS and MongoDB in Hindi. Also, how to Securely Add projects in GITHUB in Hindi
What is The dotenv module in Hindi?
The dotenv is a zero-dependency module that loads environment variables from a .env file into process.env. Storing configuration in the environment separate from code is based on the Twelve-Factor App methodology.
Environment variables Environment variables allow us to manage the configuration of our applications separately from our codebase. Separating configurations makes it easier for our application to be deployed in different environments.
Environment variables are variables external to our application that reside in the OS or the container where the production application is running. Because development is mostly done on local machines, environment variables are put either to local environment variables with commands such as asset or export, or stored in the local .env file.
By convention, the variables are written in uppercase letters (e.g. PORT).
Common examples of configuration data that are stored in environment variables include:
HTTP port database connection string location of static files endpoints of external services The .env file should never be committed to the source code repository. We must place the file into the .gitignore file. (When using git.)
Modern editors have support for .env files; for instance, the code has the DotENV extension.
The .env parsing rules Here are some basic parsing engine rules:
BASIC=basic becomes {BASIC: 'basic'} empty lines are skipped comments start with # empty values become empty strings; BASIC= becomes {BASIC: ''} inner quotes are maintained Existing environment variables are not modified; they are skipped.
