This error usually arises inside JavaScript environments, notably when builders try and entry setting variables utilizing `import.meta`. `import.meta` gives metadata concerning the present module, however commonplace JavaScript doesn’t embrace setting variables inside this object. Making an attempt to entry a non-existent property, akin to `env`, outcomes on this error message. A typical state of affairs entails builders migrating from Node.js, the place `course of.env` gives entry to setting variables, to browser-based environments or different JavaScript runtimes the place this method will not be immediately obtainable.
Understanding the excellence between server-side and client-side environments is essential for resolving this challenge. Server-side environments like Node.js have direct entry to system setting variables. Nonetheless, for safety and architectural causes, client-side JavaScript working in an internet browser doesn’t have this direct entry. Exposing setting variables on to the client-side may pose safety dangers. Correctly managing setting variables is significant for utility safety and configuration. Completely different approaches exist for dealing with setting variables in client-side JavaScript, together with build-time injection, server-side APIs, and devoted client-side libraries.
