No more 'field' events will be emitted.For the French composer, see Henri Büsser. No more 'file' events will be emitted.įieldsLimit() - Emitted when the configured limits.fields limit has been reached. No more 'file' or 'field' events will be emitted.įilesLimit() - Emitted when the configured limits.files limit has been reached. PartsLimit() - Emitted when the configured limits.parts limit has been reached. MimeType - string - The field's 'Content-Type' value. ValueTruncated - boolean - Whether value was truncated or not (due to a configured limits.fieldSize limit)Įncoding - string - The field's 'Content-Transfer-Encoding' value. NameTruncated - boolean - Whether name was truncated or not (due to a configured limits.fieldNameSize limit) value contains the string value of the field.
Note: If a configured limits.fileSize limit was reached for a file, stream will both have a boolean property truncated set to true (best checked at the end of the stream) and emit a 'limit' event to notify you when this happens.įield(name, value, info) - Emitted for each new non-file field found. However, if you aren't accepting files, you can either simply not listen for the 'file' event at all or set limits.files to 0, and any/all files will be automatically skipped (these skipped files will still count towards any configured limits.files and limits.parts limits though). Note: If you listen for this event, you should always consume the stream whether you care about its contents or not (you can simply do stream.resume() if you want to discard/skip the contents), otherwise the 'finish'/ 'close' event will never fire on the busboy parser stream. MimeType - string - The file's 'Content-Type' value. You are better off generating your own (safe) filenames, or at the very least using a hash of the filename.Įncoding - string - The file's 'Content-Transfer-Encoding' value. WARNING: You should almost never use this value as-is (especially if you are using preservePath: true in your config) as it could contain malicious input. info contains the following properties:įilename - string - If supplied, this contains the file's filename. base64 to raw binary) are done on the file's data. stream is a Readable stream containing the file's data. (Special) Parser stream eventsįile(name, stream, info) - Emitted for each new file found. For example, if the Content-Type in headers is missing entirely, is not a supported type, or is missing the boundary for 'multipart/form-data' requests. This function can throw exceptions if there is something wrong with the values in config. Default: 2000 (same as node's http module). HeaderPairs - integer - For multipart forms, the max number of header key-value pairs to parse. Parts - integer - For multipart forms, the max number of parts (fields + files). Default: Infinity.įiles - integer - For multipart forms, the max number of file fields. Default: Infinity.įileSize - integer - For multipart forms, the max file size (in bytes). Default: 1048576 (1MB).įields - integer - Max number of non-file fields. Default: 100.įieldSize - integer - Max field value size (in bytes). Valid properties are:įieldNameSize - integer - Max field name size (in bytes).
