Amplify-token NPM

Amplify Token

Generate a AWS Amplify Auth Token using your AWS configuration and Cognito credentials via a CLI.

Installation

Amplify Token requires Node.js version 12 or above. To install, run the following command from any directory in your terminal:

npm install amplify-token -g

Currently the project has only been tested on macOS Monterey but has no obvious limitations so should work on both modern and legacy versions of Windows and macOs.

Important: Running npm install amplify-token -g in CI means you're always installing the latest version of the CLI, including breaking changes.

Usage

Installing the CLI globally provides access to the amplify-token command.

amplify-token [command]

# Run `--help` for detailed information about CLI commands
amplify-token [command] --help

Commands

There are two main commands provided with amplify-token: config and fetch.

config

Interact with the config store where your variables to interact with AWS are saved.

Subcommand	description
`--set`	Set a key and value in the config store (requires two arguments)
`--get`	Get a value from the config store (requires one argument)
`--get-all`	Gets all current values from the config store
`--clear`	Clears the config store of all values

Example

fetch

Attempt to communicate with AWS using the configuration settings. If successful, the user will be prompted for an email and password. If the credentials are valid, the JWT will be provided.

Example

amplify-token fetch

AWS Auth

Authentication with Cognito/Amplify can be a little nuanced. Taken directly from the docs, these are example settings that can be set in the config store before running fetch
