Middleware for parsing and extending Express request

Express Request Parser

This handy middleware:

• parses multipart requests,

• parses json requests,

• parses urlencoded requests,

• adds a bunch of useful methods to coerce request parameters:

  • req.getString retrieves a string (or an empty string if no parameter found)
  • req.getStrings retrieves an array of strings (or an empty array if no parameter found)
  • req.getInteger retrieves an integer (or 0 if not an integer)
  • req.getIntegers retrieves an array of integers (skipping non-integers)
  • req.getNumber retrieves a number (or 0 if not an number)
  • req.getNumbers retrieves an array of numbers (skipping non-numbers)
  • req.getMoment parses a string date in YYYY-MM-DD format (or default value)
  • req.getMoments parses an array of moment dates (skipping invalid ones)
  • req.getFile retrieves a file parsed from multipart form
  • req.getFiles retrieves an array of files

Each file is represented by an object with following keys:

• name — original filename as submitted by user with slashes and semicolons removed;
• safeName — filename converted to ASCII to be safely stored in virtually any FS;
• type — value of Content-Type header as submitted by browser;
• path — path to temporary storage so that you could move it to its final place with fs.rename(file.path, destination, cb).
