This module is for publishing source maps to New Relic Browser. It can be used from the command line or programatically from a node script.

Published source maps are used to automatically unminify stack traces for JavaScript errors in the New Relic Browser Monitoring product.

Please see the source map documentation for more details.

npm install -g @newrelic/publish-sourcemap

publish-sourcemap [dist/ ||] []  --applicationId=[ID] --nrAdminKey=[apiKey]

  --applicationId  Browser application id (APPLICATION_ID)
  --nrAdminKey     New Relic admin api key (NR_ADMIN_KEY)
  --releaseName    [Optional] unique identifer for the release name
  --releaseId      [Optional] unique version for the release identifier

list-sourcemaps --applicationId=[ID] --nrAdminKey=[apiKey] --limit=[20] --offset=[0]

  --applicationId  Browser application id (APPLICATION_ID)
  --nrAdminKey     New Relic admin api key (NR_ADMIN_KEY)
  --limit          Max number of results to return, default 20

The module can also be used from a JavaScript build tool such as gulp.

npm install --save-dev @newrelic/publish-sourcemap
var publishSourcemap = require(‘@newrelic/publish-sourcemap’).publishSourcemap
  sourcemapPath: './dist/', // from a local file 
  // sourcemapUrl: '', // or from a URL 
  javascriptUrl: '',
  applicationId: 1234,
  nrAdminKey: 'APIKEY',
}, function (err) { console.log(err || 'Source map upload done')})
var deleteSourcemap = require(‘@newrelic/publish-sourcemap’).deleteSourcemap
  sourcemapId: 'aaaaaaaa-bbbb-1010-bbbb-cccccccccccc',
  applicationId: 1234,
  nrAdminKey: 'APIKEY',
}, function (err) { console.log(err || 'Deleted source map')})
