![]() We saw how to set and use the NODE_ENV environment variable, its purpose, and its uses. We saw how it is similar to any other environment variable but can be a handy tool when we want to write some environment-specific code or logic. Generally, the variable definition is provided on a separate line.Ĭonclusion: We have pretty much covered all about NODE_ENV in this article. Yet another meticulous rule is that there cannot be space around the equals sign when you are assigning values to the variables, e.g. Environment variables are special variables that can be set out of your Node.js applications, particularly useful to make your application configurable. env is a shell file, eliminating the need to wrap names or values in quotes. It is a secret file that cannot be accessed by anyone except the developer and hence can be used to store private/secret/ hidden data ( data that you cannot afford to make public, i.e., it is vulnerable data), it can be used to store API keys from external services. env file in the root of your project directory and it acts as a hidden file that is used to pass environment variables to the application. In such a case, it will only be applied to the process from which it was set. It is a bad idea to set NODE_ENV from within an application.If NODE_ENV is not set explicitly for the environment and accessed using process.env then it will be undefined. ![]() env files in NodeJS - this is done using the popular 'dotenv' package.env files are used to. We can use app.get(‘env’) function provided by express to get the value of NODE_ENV but it defaults to “development” rather than production otherwise. In today's video I'll take you through using.Here we set 2 variables for APIKEY and APISECRET. In the same way you can access any custom environment variable you set.
