Unable to bundle Node.js with Appdynamics using Webpack (broken dependencies?)

When trying to install the AppDynamics package for monitoring a Node.js application, our Webpack build process is not able to import a handful of dependencies. Specifically, the errors output are:

Our project is set up with:
- Webpack v4.29.0
- Node.js v11.0.0
- Appdynamics v4.5

The Appdynamics usage is at the top of our server file as:

// AppDynamics monitoring
require("appdynamics").profile({
controllerHostName: ***
controllerPort: 443,
controllerSslEnabled: true,
accountName: ****
accountAccessKey: ***
applicationName: ***
tierName: ***
nodeName: '01'
});

 

And our Webpack configuration is:

const path = require('path');
const webpack = require('webpack');

module.exports = {
entry: { server: './server.ts' },
resolve: { extensions: ['.js', '.ts'] },
target: 'node',
mode: 'development',
// this makes sure we include node_modules and other 3rd party libraries
externals: [/node_modules/],
output: {
path: path.join(__dirname, 'dist'),
filename: '[name].js'
},
module: {
rules: [{ test: /\.ts$/, loader: 'ts-loader' }]
},
plugins: [
]
};

 

So far we have tried downgrading the Webpack version, downgrading the Node environment to 10.15, and using other import methods for the AppDynamics package, but this seems like an issue internal to the Appdynamics library?

Has anyone experienced anything similar? Or had success using the Appdynamics node package with Webpack?

Hi Cody,

 

Could you try adding "appdynamics" to the externals array? Let me know if that helps.

 

Thanks and regards,

Kyle

Thank you Kyle, that did the trick!

Re: Unable to bundle Node.js with Appdynamics using Webpack (broken dependencies?)

The other fix I see is as below:

ensure you're installing the 4.5.11 or higher version of the agent (@latest will work)

  1. install with npm install
  2. edit the package-lock.json file to remove the lines and sections that show jre / proxy
  3. "appdynamics-jre": "https://packages.appdynamics.com/nodejs/4.5.11.0/appdynamics-jre.tgz",
  4. "appdynamics-proxy": "https://packages.appdynamics.com/nodejs/4.5.11.0/appdynamics-proxy.tgz",
  5. "appdynamics-jre": { "version": "https://packages.appdynamics.com/nodejs/4.5.11.0/appdynamics-jre.tgz", "integrity": "sha512-hmnixIubwz8TBxQMe1/5QYwxmrCsnimYrZvNbvWZHOx2XifRnenzaPHw3avFCTvXgkTWt5lsY3UBIqlDYxTg3Q==" },
  6. "appdynamics-proxy": { "version": "https://packages.appdynamics.com/nodejs/4.5.11.0/appdynamics-proxy.tgz", "integrity": "sha512-1E+UxBrR4Vo0FAG0z+66RYx3dGZfb55W+6G/lTnDxt3U0TZUzA/rKo9PaQNDLKwogcgkraZYgBFYlVsvtvQy4w==" },

Re: Unable to bundle Node.js with Appdynamics using Webpack (broken dependencies?)

I’ve also had to do similar within our yarn.lock file, specifically when encountering:
info Visit https://yarnpkg.com/en/docs/cli/install for documentation about this command.
error https://packages.appdynamics.com/nodejs/4.5.11.0/appdynamics-proxy.tgz: Integrity check failed for "appdynamics-proxy" (computed integrity doesn't match our records, got "sha1-wcdDKNB8QnI4D/YdYd+hAc6Ywy4=")

It seems like there is something about the node.js AppDynamics library which, at minimum, isn’t configured in a typical way. Maybe it’s just related to how they host their own children dependencies?
