javascript - SyntaxError: Unexpected token function

Making a chat application referencing via Node in action, and upon running the server.js, got the following error: function serveStatic(response,cache,absPath) ^^^^^^^^ SyntaxError: Unexpected token function at Object.exports.runInThisContext (vm.js:73:16) at Module._pile (module.js:543:28) at Object.Module._extensions..js (module.js:580:10) at Module.load (module.js:488:32) at tryModuleLoad (module.js:447:12) at Function.Module._load (module.js:439:3) at Module.runMain (module.js:605:10) at run (bootstrap_node.js:418:7) at startup (bootstrap_node.js:139:9) at bootstrap_node.js:533:3

2 filePath= public/index.html; is missing quotes and 'public' + request.url; is a no-op that does nothing ... – Alex K. Commented Jul 3, 2017 at 12:21
@AlexK. , got these missing quotes at the place now, still the same error as shown above – raman bhayana Commented Jul 3, 2017 at 12:25
you seem to have a few extra random } and a random ) as well - indent your code properly to see the problem – Jaromanda X Commented Jul 3, 2017 at 12:29
@JaromandaX - Yeah having little extra braces , correct it out now and working fine. – raman bhayana Commented Jul 3, 2017 at 12:37

Sorted by: Reset to default 1

You have extra brackets here:

function sendFile(response,filePath,fileContents)
{
    response.wrieHead(200,
       {"content-type":mime.lookup(filePath)})

       };
       response.end(fileContents);

}

Should be modified this way:

function sendFile(response, filePath, fileContents)
{
    response.wrieHead(200, {
      "content-type": mime.lookup(filePath)
    });
    response.end(fileContents);

}

Then your error will be dismissed.

In my case setting the buildOptimizer from false to true worked.

From:

"development": {
  "buildOptimizer": false,
  "optimization": {
    "scripts": true,
    "styles": {
      "minify": true,
      "inlineCritical" : false
    },
    "fonts": true
  },
  "vendorChunk": true,
  "extractLicenses": false,
  "sourceMap": true,
  "namedChunks": true
}

To:

"development": {
  "buildOptimizer": true,
  "optimization": {
    "scripts": true,
    "styles": {
      "minify": true,
      "inlineCritical" : false
    },
    "fonts": true
  },
  "vendorChunk": true,
  "extractLicenses": false,
  "sourceMap": true,
  "namedChunks": true
}
