We support the [LTS versions](https://nodejs.org/en/about/releases) of Node. ## Base commands ### BaseCommand The base command class for _all_ twilio-cli commands. Includes support for configuration management, logging, and output formatting. ### TwilioClientCommand A base command class for commands that need a Twilio client to make API requests. Handles loading credentials from the profile configuration. ## Services ### Output formats Formatters to take a JSON array and write to the stdout. Current formatters include: - Columns (default, human readable) - JSON (raw API output) - TSV ### CliRequestClient A custom http client for the Twilio helper library to allow us to log API requests as well as modify the User-Agent header. ### Usage with proxy - `HTTP_PROXY`: If using Twilio CLI behind a proxy, set the URL of the proxy in an environment variable called `HTTP_PROXY`. ### Config Manages the CLI configuration options, such as Twilio profiles and credentials. ### Logger Standardizes logging output of debug, info, warning, and error messages to stderr (all go to stderr to allow differentiation between command output and logging messages). --- _Source: https://npm.io/package/@twilio/cli-core · Machine-readable twin of the npm.io package page.
