I am working on node.js project with nest.js framework and I had the error "JavaScript heap out of memory" my question is how to allocate more memory to my app?. Also I found some people say that I should use [--max-old-space-size] to allocate memory so I tried to add this option to package.json scripts to have "start" : "nest start --max-old-space-size=4096" but it didn't work

npm-scripts nestjs express node.js javascript

Nest passes some, but not all, flags through to node. This is one of the flags that it does not. Instead, you can use node dist/main --max-old-space-size=4096 and get the server to start that way.

Jay McDoniel was right about this, however the argument is in the wrong order, you must pass like this node --max-old-space-size=4096 dist/main

Make sure you do a npm run build if you haven't before.
