Integration of newrelic in a universal angular application (nodejs)

Question

I am integrating newrelic into a nodejs application made with angular universal. I use webpack to bundle

first line in main.server.aot.ts

const newrelic = require('newrelic');

and added newrelic.js to the root directory.

running build produces the following error: -

ERROR in ./node_modules/@newrelic/native-metrics/lib/pre-build.js
Module not found: Error: Can't resolve '../package' in 'D:\repos\ib-mobile\node_modules\@newrelic\native-metrics\lib'
 @ ./node_modules/@newrelic/native-metrics/lib/pre-build.js 40:12-33
 @ ./node_modules/@newrelic/native-metrics/index.js
 @ ./node_modules/newrelic/lib/sampler.js
 @ ./node_modules/newrelic/lib/agent.js
 @ ./node_modules/newrelic/index.js
 @ ./src/main.server.aot.ts

 @ ./node_modules/newrelic/index.js
 @ ./src/main.server.aot.ts

ERROR in ./node_modules/newrelic/index.js

 @ ./node_modules/newrelic/index.js 13:19-39
 @ ./src/main.server.aot.ts

and if I add newrelic as externals to the webpack configuration

module.exports = {
  entry: root('./src/main.server.aot.ts'),
  output: {
    path: root('dist_server'),
    filename: 'server.js'
  },
  target: 'node',
  externals: {
    newrelic: true
  }
};

then I get another error:

/home/ubuntu/ib-mobile/dist_server/server.js:79752

module.exports = newrelic;
                 ^

Found a hacker way around this problem!

TL; DR

, , - webpack server.js, BAM .

, , , , , webpack, , newrelic , , newrelic . , , , . , <script src="{http://example.com/script.js}"/> , <script src="{http://example.com/script.js}"/> , - . node_modules.

"externals" nodejs import var newrelic = require('newrelic'); , expressjs ( , ).

:

• BannerWebpackPlugin
• , / nodejs express.

BannerWebpackPlugin, : npm install --save-dev banner-webpack-plugin

/, ( , server.js):

ReferenceError: newrelic is not defined at Object.<anonymous> (/home/ubuntu/ib-mobile/dist_server/server.js:79752:18)

"entry" - , - ( "", server.js.)

, , webpack.

:

plugins: [
...,
    new BannerPlugin({
        chunks: {
            server:{
                beforeContent: 'var newrelic = require("newrelic");'
            }
       }
    }),
...]

- !

, , - newrelic.

. webpack externals :

(context, request, callback) => {
    var regex = new RegExp('^newrelic$');

    if (regex.test(request)) {
        return callback(null, 'commonjs ${request}');
    }
    callback();
 }

- const newrelic = require('newrelic'); . , , node_modules newrelic . , libraryType output commonjs externals :

externals : {
    newrelic : {
        commonjs: 'newrelic'
    }
}
