cross-env VS dotenv

cross-env

or if we care about cross-platform compatibility (i.e. Windows support), we can use cross-env (which I also recommend to install as a dev dependency):

i like to use dotenv-flow and dynamically load it into node process. it's framework agnostic and can be combined with vaious other strategies, like explicitly set NODE_ENV with cross-env. all you need is the right command in your package.json, see a sample here.

Cross-env runs scripts that set and use environment variables across various platforms.

You will also need to disable the url-loader in your Docusaurus build which transforms images into base64 strings, as this will conflict with the plugin. There isn't a first class way to do this in Docusaurus at present. However by setting the environment variable WEBPACK_URL_LOADER_LIMIT to 0 you can disable it. You can see an implementation example in this pull request. It amounts to adding the cross-env package and then adding the following to your package.json:

Using the cross-env library, you'll tell the React Testing Library to skip auto cleanup after each test. More info and ways to configure here: Skipping Auto Cleanup. Now your configuration is enough to start writing tests, let's get started.

Now we need to load the files during the bootup. Windows environments sometimes face issues with loading the environments. To take care of that, let's install a package named cross-env

build; sets and enviroment valiable of NODE_ENV=production using cross-env lib and builds the production bundle, minified and without source-maps as set in the webpack.config.js file.

I'd suggest the cross-env NPM package which is used a lot (4M downlaods/week). Then you can just change it to the following:

Debugging Cypress tests using Visual Studio Code was possible earlier but with the latest version of Cypress, there is no direct way to do so. Even with the latest version of Cypress, a workaround was possible using Debugger for Chrome – a Visual Studio Code Extension and cross-env npm package. However, the Debugger for Chrome Extension for Visual Studio Code is deprecated and the cross-env npm package has gone into maintenance mode.

We will put our Emailjs environment variables in a dotenv (.env) file. To read more about the purpose of this file click here.

Add .env to your .gitignore file to prevent it from being committed. Here's an example file with it already added. You may also use dotenv for advanced configuration and it will automatically load environment variables from a .env file into process.env.

dotenv: Designed to load environment variables from a .env file into the process.env environment

Like Doppler, Infisical uses environment variable injection. Similar to the Dotenv package for Node, when used in Node, it injects them at run time into the process object of the running app so they're not readable by any other processes or users. They can still be revealed by a crash dump or logging, so that is a caveat to consider in your code and build scripts.

We'll be working with databases' ids and different info that should be secured so I would advise you to create a .env file to store said info. We'll do this by installing dotenv into our project and use it accordingly:

dotenv - For reading our API keys from the environment

As an avid dotenv user I wanted to thank their maintainers for keeping the project alive for 10 years (wow). A perfect exemplary of dedication to Open Source.

Sensitive data like database URLs, API keys, and passwords should never be hardcoded in your application code. Instead, use environment variables accessed at runtime to keep this information secret. Popular dotenv libraries like dotenv make this easy for Node.js apps.
