This error sometimes arises inside JavaScript environments, significantly when builders try to entry atmosphere variables utilizing `import.meta`. `import.meta` supplies metadata in regards to the present module, however customary JavaScript doesn’t embrace atmosphere variables inside this object. Trying 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` supplies entry to atmosphere variables, to browser-based environments or different JavaScript runtimes the place this method is just not straight out there.
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 atmosphere variables. Nonetheless, for safety and architectural causes, client-side JavaScript working in an online browser doesn’t have this direct entry. Exposing atmosphere variables on to the client-side may pose safety dangers. Correctly managing atmosphere variables is important for utility safety and configuration. Totally different approaches exist for dealing with atmosphere variables in client-side JavaScript, together with build-time injection, server-side APIs, and devoted client-side libraries.
