Webpack Package "JavaScript heap out of memory" error

Problem

Development projects for some time, as the project is getting bigger, the packaging time is correspondingly longer, and the memory of packaging increased. At this point, there is a problem, when publishing the project, there will be a JavaScript heap out of memory wrong hint.
Such as:

The above error has been causing the project to be published.
Detailed Error content:CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

Reason

Node JavaScript only partial memory (64-bit system: 1.4 gb,32 Bit system: 0.7 GB) can be used when using memory in, at this time, if the front-end project is very large, the Webpack compile time will occupy a lot of system resources, if it is beyond the V8 engine Node The default memory limit size creates a memory leak (JavaScript heap out of memory) error.

Solution Solutions

Since the V8 engine has a Node default memory limit size, you can relax the memory size usage limit when the memory is low, and Node you can Node pass --max-old-space-size or adjust the --max-new-space-size memory size usage limit at startup.
But this approach needs to be set up everywhere, so a plugin needs to be installed increase-memory-limit .

Use the following methods:

• Installation
  npm install -g increase-memory-limit
• Run
  increase-memory-limit
• NPM runs asynchronously

"scripts": {    "fix-memory-limit": "cross-env LIMIT=2048 increase-memory-limit"  },  "devDependencies": {    "increase-memory-limit": "^1.0.3",    "cross-env": "^5.0.5"  }

Execute oncenpm run fix-memory-limit

Plugin: Increase-memory-limit
