after installing this plugin getting heap out of memory error

[skirankumar7]

ISSUE:

Actually I am using node webpack-server.js to run webpack server
but after installing webpack-dashboard plugin I am running the command
npm run start-webpack

"scripts": {
"make-dll": "webpack -p --config webpack.dll.config.js --progress --profile --mode production",
"start": "node bin/www",
"start-webpack": "webpack-dashboard -- node webpack-server.js",
"build": "webpack --config webpack.prod.config.js --progress --profile ",
"webpack": "node --max-old-space-size=12288 node_modules/webpack/bin/webpack.js"
},

Your build seems to already need a lot of extra memory, so try adding --max-old-space-size=12288 to the webpack-dashboard script maybe something like:

"start-webpack": "webpack-dashboard -- node --max-old-space-size=12288 webpack-server.js",

If that doesn't resolve the issue, please see if you can put together a minimal repository with install + error reproduction steps so that we can jump in and reproduce your issue. Thanks!
