Summary

Firebase CLI provides a flexible alternative to manually editing Firebase Realtime Database data in the console, enabling developers to script database operations for setup, testing, and Cloud Functions trigger validation. After configuring a project and logging in, users can write JSON data with `database:set` from files, inline command-line data, or standard input, with confirmation safeguards for potentially destructive writes. The CLI also supports retrieving data with `database:get`, saving or pretty-printing JSON output, and applying query ordering and limits, while `database:push` creates uniquely keyed records, `database:update` changes selected fields without replacing an entire node, and `database:remove` deletes data and requires particular caution. Database contents can be copied between Firebase projects by piping a read command into a write command and selecting projects with the `--project` option, and recurring tasks can be streamlined through Bash functions such as a reusable project-to-project transfer command.
