This error sometimes arises inside JavaScript environments, notably when builders try to entry surroundings variables utilizing `import.meta`. `import.meta` supplies metadata concerning the present module, however commonplace JavaScript doesn’t embody surroundings variables inside this object. Making an attempt to entry a non-existent property, equivalent to `env`, outcomes on this error message. A typical situation entails builders migrating from Node.js, the place `course of.env` supplies entry to surroundings variables, to browser-based environments or different JavaScript runtimes the place this method just isn’t instantly out there.
Understanding the excellence between server-side and client-side environments is essential for resolving this problem. Server-side environments like Node.js have direct entry to system surroundings variables. Nonetheless, for safety and architectural causes, client-side JavaScript operating in an online browser doesn’t have this direct entry. Exposing surroundings variables on to the client-side might pose safety dangers. Correctly managing surroundings variables is significant for software safety and configuration. Totally different approaches exist for dealing with surroundings variables in client-side JavaScript, together with build-time injection, server-side APIs, and devoted client-side libraries.
