Detect installed code formatters and format files with them.

Detect the preferred formatter used in the project.

import { detect } from "@changesets/format";

const result = await detect();
// => "prettier"

Options can be passed to the first parameter:

• cwd: The current working directory to start looking up for the formatter. Defaults to process.cwd().
• stopDir: The path to stop traversing up the directory.
• order: The order of formatters to check for. Defaults to ["dprint", "deno", "oxfmt", "biome", "prettier"] (from defaultDetectOrder)

Format the given patterns with a specified or auto-detected formatter. It returns true if a formatter is found and the formatting process passes (even if the patterns didn't match any files), otherwise returns false.

import { format } from "@changesets/format";

await format(["src/index.ts"]);

Options can be passed to the second parameter:

• formatter: The formatter to use for formatting. It not specified, it will be auto-detected using detect. Use detect directly if you want to have more control over the detection process.
• cwd: The current working directory to start looking up for the formatter and package manager, and to execute the formatter's command from. Defaults to process.cwd().
• stopDir: The path to stop traversing up the directory.
• packageManager: The package manager to use for executing the formatter's command. If not specified, it will use package-manager-detector to detect the package manager.

The core idea of this package is based on formatly, but implemented for Changesets' needs. However, it is still generic enough to be used by other projects than Changesets.
