Error: Unable to read configuration file newrelic.js - node.js

Question

I’m getting this error:
Error: Unable to read configuration file newrelic.js.
A base configuration file can be copied from 536 and renamed to in the
directory from which you will start your application.
Project is Angular 7 SPA with SSR.

Answer 1

There are two solutions:
The first by bj97301 on official new relic forums.
in my webpack config file, make newrelic external:
externals: ['newrelic']
in my webpack config file, use commonjs as my output library target:
output: { libraryTarget: 'commonjs'}
change newrelic.js to use exports. instead of export:
was: export const config = {
now: exports.config = {
This methods won't work if you want to deploy a whole package to remove server since you excluded the new relic package.
To solve this, you can use the second method.
As a workaround, change newrelic.js to override Environment variable instead of exporting the config.
e.g.
process.env.NEW_RELIC_NO_CONFIG_FILE = 'true';
process.env.NEW_RELIC_APP_NAME = 'YOUR APP NAME';
process.env.NEW_RELIC_LICENSE_KEY = 'YOUR_KEY';
process.env.NEW_RELIC_LOG_LEVEL = 'warn';
process.env.NEW_RELIC_ALLOW_ALL_HEADERS = 'true';
console.log('New relic has been configurated.');
And you can remove the original config that was exported:
'use strict';
exports.config = {
app_name: [],
license_key: '',
logging: {
level: 'warning'
},
allow_all_headers: true
}
Don't forget to require on your server.ts, simply add:
require('./newrelic');
I hope it would save someone some hours.
