Is there any way I can increase the heap size of the node process?

node.js intellij-idea

There is a hidden option that allows passing arguments to Node.js process that runs TypeScript service - typescript.service.node.arguments.

  • in Help | Find action..., type registry
  • open Registry, locate typescript.service.node.arguments key there (you can start typing property name to navigate to it)
  • add --max_old_space_size option there (--max_old_space_size=4096, for example)

See https://github.com/thlorenz/v8-flags/blob/master/flags-0.11.md#max_old_space_size-0-integer

See also https://www.npmjs.com/package/increase-memory-limit - you may find this utility helpful
