FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

See original GitHub issue

Hi,

I try to prerender a relative big amount of page in webpack, ~800 pages. Webpack never end and throw me next error: FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

As recomend, I use @prerenderer/renderer-jsdom

Here my plugin config, I don’t understand why it take so many memory In my test I limit the 800 pages to first 200 and 1494Mb seem not be enough

const PrerenderSpaPlugin = require('prerender-spa-plugin')
const JSDOMRenderer = require('@prerenderer/renderer-jsdom')

            new PrerenderSpaPlugin({
              renderer: new JSDOMRenderer({
                  maxConcurrentRoutes: 50,
                  renderAfterDocumentEvent: 'app-rendered',
                  renderAfterTime: 4000
              }),
              staticDir: path.join(__dirname, '../build'),
              outputDir: path.join(__dirname, '../build'),
              routes: urlsToPrerender,
              // renderAfterDocumentEvent: 'app-rendered',
              postProcess (renderedRoute) {
                  const $ = cheerio.load(renderedRoute.html)

                  $('head').children().each(function() {
                      var Src = this.attribs.src

                      if(Src !== undefined) {

                          if(Src.indexOf('maps.googleapis.com') !== -1) {
                              $(this).remove();
                          }
                      }
                  });

                    renderedRoute.html = $.html()

                    return renderedRoute
                },
            })

Thanks for your help
