"Uncaught ReferenceError: process is not defined" and the solution 📎
Uncaught ReferenceError: process is not defined
happens when when a non-existent (here: process) variable is referenced.
Most likely the problematic code snippet looks like:
var isProduction = process.env.NODE_ENV === 'production';
The process.env property is available on node,
but not in the browser which causes the above error.
To fix the problem, define the variable pro-actively before the library is loaded, e.g.:
window.process = {
env: {
NODE_ENV: 'development'
}
}
The fix/script can be loaded with e.g.:
<script src="init.js"></script>
