示例1: detect

export function detect(filename: string=null, buffer: Buffer=null): DetectionResult | null {
  if (filename !== null) {
    const mimeType = filenameToTextMimetype(filename);
    if (mimeType !== null) {
      return {mimeType, charset: null };
    }

    const imageMimeType = mimeTypes.lookup(filename);
    if (imageMimeType !== null && imageMimeType !== false) {
      return { mimeType: imageMimeType, charset: null };
    }
  }

  // Check the data directly.
  if (buffer !== null) {
    const fileTypeResult = filetype(buffer);
    if (fileTypeResult !== null) {
      return {mimeType: fileTypeResult.mime, charset: null };
    }

    if ( ! isNotText(buffer)) {
      const result = jschardet.detect(buffer.slice(0, SAMPLE_SIZE).toString());
      if (result.encoding !== null && result.confidence > 0.8) {
        return { mimeType: "text/plain", charset: result.encoding };
