If you've decided to build a custom app or modify one of our open source apps, you need a few essential tools:

Depending on what you want to do with your app, you might have some additional setup and configuration. This guide covers:

  • Downloading the New Relic One CLI to build or modify apps
  • Contribute content to this website

Before you begin

You must have:

A note on support

Building a New Relic One application is the same as building any JavaScript/React application. We offer support to help with our building tools (our CLI and SDK library). However, we don't offer support for basic JavaScript or React coding questions or issues.

For common questions and answers about building, see the Explorers Hub page on building on New Relic One.

Tip

Use the New Relic One VSCode extension to build your apps.

Prepare to build or modify apps

Step 1 of 1

Download the CLI and API key.

On the Build New Relic One applications page, complete the Quick start steps.

These six Quick start steps get you an API key for use with developing apps, and the New Relic One CLI, for building and deploying apps. At the end of the Quick start, you have a project consisting of the following:

  • A Nerdpack - The package containing all the files required by your application. It contains two types of files that you customize to build your app: Nerdlets, and the launcher.
  • One or more Nerdlet files - A specific UI view or window. A Nerdlet is a React JavaScript package that includes an index.js file, a stylesheet, and a JSON-format config file. It can contain any JS functionality (charts, interactive fields, tooltips, etc.).
  • A launcher file: This is the basis for the launcher, which is used to open your application from New Relic One after you publish your app.

Start building

Step 1 of 1

If you're ready to code, cd to your Nerdpack and get started.

If you want to learn more about building applications, try these step-by-step guides:

  • Build a "Hello, World!" application shows how to create a little application, publish it to New Relic One, and share it with others by subscribing accounts to it.
  • Map pageviews by region takes you through the steps to create one of our popular open source apps. You learn to add a custom query to an app and view it in a table, then add that data to a map.

Contribute to developer.newrelic.com

This site is open source, and we want your input. Create a pull request if you see a mistake you know how to fix. Drop us a GitHub issue if you see some content gaps you want us to work on. Or write up a whole new guide if you have one you'd like to share. Read on to learn how.

Step 1 of 3

Fork the developer-website GithHub repo.

Forking the repo enables you to work on your own copy of the developer.newrelic.com files, and build the site locally. It also enables us to more easily manage incomimg pull requests.

  • On the developer-website page in GitHub, select the Fork button on the top right of the page, choose the account you want to fork to, and wait a few seconds while the fork is created.

Sync regularly to keep your fork up to date with changes and additions to the main branch upstream.

Step 2 of 3

Make a feature or documentation request.

  • On any page, select the GitHub button at the top of the page, and then select the kind of change you want, and fill out the GitHub form.

Step 3 of 3

Contribute a new guide.
