Ampli CLI

Ampli is Amplitude's command line app. It works hand-in-hand with the Amplitude Data web app and enables developers to correctly instrument tracking code in their apps.

Install Ampli

Install Ampli from Homebrew or npm.

1brew tap amplitude/ampli
2brew install ampli

1brew upgrade ampli

1npm install -g @amplitude/ampli

Initialize and connect Ampli and Amplitude Data

Now that you have Ampli installed, cd into your project's root folder and initialize it with:

1ampli pull

A browser window opens and automatically logs you in or prompt you for your credentials. Ampli stores your project-specific settings in ampli.json and your user-specific settings (such as your credentials) in ~/ampli.json. Depending on your Amplitude organization settings, the CLI might prompt you to choose your Organization or Workspace.

 1➜ ampli pull

Generate your analytics SDK

The ampli pull command looks at the events and properties you've defined in your Amplitude Data account (also known as a tracking plan). Ampli uses this information to create a matching type-safe analytics library for you to use.

1ampli pull {source-name}

The pull command takes one (optional) argument: the name of a source created in your Amplitude Data account. For example, a source might be ios, android, web, or backend. Follow the prompt options to configure a newly created source. Events associated with a particular source appear in the autogenerated SDK. Those that aren't don't. This makes sure Amplitude tracks your events consistently across all sources you track them on.

The pull command also tells you what, if anything, has changed since the last time you pulled your team's analytics spec. You can use this as a guide for getting your analytics instrumentation up-to-date.

As your project progresses, you and your team make changes to your tracking plan. Amplitude Data notifies you when something changes and when you’re ready, you can pull down the changes and incorporate them into your project.

Instrument your product

After you have pulled down the latest tracking plan, learn how to instrument your product.

Verify the instrumentation

To make sure you’re tracking all the right events, and that you’re tracking those events correctly, Ampli can lint your source code and warn you about any errors. For example, Ampli can tell if you’ve forgotten to track any required events, or if you’re not passing along all required properties.

1ampli status --update

The verify command scans your source code for tracking calls and compare the results to what's expected per your team's tracking plan. Include --update to update your company's tracking plan online and share the latest analytics implementation status with your team.

You can configure your CI pipeline to automatically run the ampli status command at check-in.

Ampli commands

Pull

Pull down the latest tracking plan and generate a tracking library.

 1USAGE
 2  $ ampli pull [<source>] [-p <path>] [-b <branch>]
 3 
 4OPTIONS
 5  -b, --branch=branch    the branch to pull
 6  -p, --path=path        where the tracking library will be created
 7  -t, --token=token      personal API token to authenticate with
 8  -v, --version=version  the version to pull
 9  --include-api-keys     include api keys to the tracking library (default true)
10  --omit-api-keys        omit api keys from the tracking library (default false)
11 
12EXAMPLES
13  $ ampli pull
14  $ ampli pull web
15  $ ampli pull web -p ./ampli -b develop
16  $ ampli pull web -p ./ampli -b develop -v 2.1.1
17  $ ampli pull --omit-api-keys
18  $ ampli pull --include-api-keys

Run this command in the root folder of your project. For example:

• Browser & Node.js: the folder with your package.json
• iOS: the folder with your Info.plist
• Android: the folder with your {project-name}.iml

By default, your tracking library is placed in:

To override the default location, pass the -p argument. Ampli retains your custom location and uses it going forward.

1ampli pull web -p ./src/analytics

Include -b {branch} to generate a tracking library from a particular branch, rather than main. By default, Ampli uses the last published version. If you'd like to generate a tracking library for another version, include
-v {version} and specify the tracking plan's version.

Status

Check the status of your instrumentation by linting (verifying) your source code for analytics.

 1USAGE
 2  $ ampli status
 3 
 4OPTIONS
 5  -b, --branch=branch                enforces source is on provided the branch
 6  -t, --token=token                  personal API token to authenticate with
 7  -u, --update                       update tracking plan with latest implementation status
 8  --instanceName                     Ampli instance name(s) to check. Default is "ampli".
 9  --is-latest                        check if current version is the latest
10  --is-latest-if-not-default-branch  check if current version is the latest (do not check if on default branch)
11  --is-merged                        check if current branch/version has been merged into default branch
12  --skip-update-on-default-branch    prevents updating implementation status on default branch
13  --sourceDir                        source code location(s). Default is current directory.
14 
15EXAMPLES
16  $ ampli status
17  $ ampli status -u
18  $ ampli status -b main
19  $ ampli status -u --skip-update-on-default-branch
20  $ ampli status --instanceName myAmpliInstance
21  $ ampli status --is-merged
22  $ ampli status --sourceDir ./src ./util

Run this command in the root folder of your project. The command
scans your source files, locate all calls to the Ampli tracking library, and
let you know which events you're tracking, and which aren't instrumented yet.

Include -u to update your company's tracking plan in Amplitude Data and share the latest analytics implementation status with your team. Your teammates can tell when events were first implemented, the last time they've
been detected in the source code, and where exactly in the code they're tracked.

If you're integrating Ampli into CI, there are typically two pipelines you want to run ampli status in:

1. Your production branch pipeline that runs when pull/merge requests get merged into your main/default branch (typically main). To make sure the code there is correct and from Amplitude Data's main branch, run ampli status -u -b main. If the Amplitude Data branch instrumented in your source code isn't main, the command fails; otherwise, it updates the main branch's tracking plan.
2. Your pull/merge request pipeline that runs when a pull/merge request is created for a branch. To verify instrumentation in this generic case, run ampli status -u --skip-update-on-default-branch. The command verifies against the current branch and only updates the tracking plan instrumentation status for branches other than main. This keeps status of events in development out of the main tracking plan.

If all events are tracked, then ampli status passes and returns an exit code of 0. Otherwise, it fails and returns the number of events that aren't tracked.

Use Ampli with a monorepo

The Ampli CLI works with a single source per project (folder). For single source projects, Amplitude recommends running ampli pull from the root directory of the repo.

In monorepos with multiple sources, you must run ampli pull and ampli status from each source's folder.

1monorepo/
2    web/
3    ampli.json (for Browser source)
4    package.json
5    backend/
6    ampli.json (for Node source)
7    package.json
