For managing python, I maintain multiple environments using conda.
i.e. for a new project, I create a new environment new-project for my new python project.
conda create -n new-project python=3.8
However, it is not clear to me how I can create new node environemnt for my different nodejs projects.
For node.js you can create your own env files that contain different values that better suites your environemnt
.env.test
API_KEY=TEST_API_KEY .env.dev
API_KEY=DEV_API_KEY to run node with this env variables
export $(xargs < ./env.test); node main.js; and to access these variables in main.js file
console.log(process.env.API_KEY); more over, you most likely are usnig npm to manage your project so use package.json scripts to ease your life
package.json
"scripts": { "start:dev" : "export $(xargs < ./env.dev); node main.js;", "start:test" : "export $(xargs < ./env.test); node main.js; } then you only do
npm run start:dev in case you are using webpack you can pass all env variables inside configuration
