If you've decided to build a custom app or modify one of our open source apps, you need a few essential tools:
- The New Relic One command line interface (CLI).
- An API key, which you get when you download the CLI.
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
Before you begin, we recommend first reading about permissions.
To start building, you must have:
- A github account account. While not strictly necessary for building apps, a GitHub account enables you to download and customize our open source apps, and contribute an open source project.
- A New Relic developer account. If you don't already have one, you can get a free trial account for developing New Relic applications.
- npm. If you've installed Node.js, then you already have
npm, which is used to share, reuse, and update JavaScript code. This necessary for working with React components that are the framework for New Relic apps and this website.
A note on support
Building a New Relic 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.
Sugerencia
Use the New Relic One VSCode extension or the New Relic VSCode extension pack to build your apps.
Prepare to build or modify apps
Download the CLI and API key
On the Build New Relic applications page, complete the Quick start steps to download.
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.jsfile, astylesheet, and a JSON-formatconfigfile. It can contain any JS functionality (charts, interactive fields, tooltips, etc.). - A
launcherfile: This is the basis for the launcher, which is used to open your application from New Relic after you publish your app.
Start building
If you're ready to code, cd to your Nerdpack and get started.

- Build a "Hello, World!" application shows how to create a little application, publish it to New Relic, 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.
