Can you get the version from package.json?

[ysknsid25]

Describe the feature

Currently, if the version cannot be obtained, an exception is thrown.

https://github.com/ysknsid25/citty/blob/7de2a6c39ec0876e0b0ecf5f07e7d2997591123e/src/main.ts#L23-L27

      const meta =
        typeof cmd.meta === "function" ? await cmd.meta() : await cmd.meta;
      if (!meta?.version) {
        throw new CLIError("No version specified", "E_NO_VERSION");
      }

Users can also define their own functions to obtain the version by using cmd.meta().

However, if we provide an option on the citty side to retrieve package.json and get the version written there, it would reduce the chances of users writing the same function 🤔

The implementation to retrieve package.json has already been implemented by an OSS called Secretlint.

https://github.com/secretlint/secretlint/blob/0bb5cbda7ac920acd4b24e354ec3167eabe6afc3/packages/%40secretlint/resolver/src/index.ts#L128-L167

/**
 * get package.json content from startDir
 * @param cwd
 * @returns package.json content
 */
export const getPackageJson = (cwd: string) => {
    try {
        const startDir = path.dirname(url.fileURLToPath(cwd));
        const packageJsonPath = findPackageJson(startDir);
        if (packageJsonPath) {
            return require(packageJsonPath);
        }
        return undefined;
    } catch (error) {
        // ignore error
        return undefined;
    }
};

/**
 * search package.json from startDir
 * @param startDir
 * @returns
 */
const findPackageJson = (startDir: string): string => {
    let currentDir = startDir;
    while (true) {
        const packageJsonPath = path.join(currentDir, "package.json");
        if (fs.existsSync(packageJsonPath)) {
            return packageJsonPath;
        }

        const parentDir = path.resolve(currentDir, "..");
        if (parentDir === currentDir) {
            return "";
        }

        currentDir = parentDir;
    }
};

(cdw=import.meta.url)

Furthermore, if there is already an implementation to get package.json in another library called Secretlint, might there be a demand for making this process itself a separate module from citty?

Please consider 🙏
