decodeFileStrict :: FromJSON a => FilePath -> IO (Maybe a)

Efficiently deserialize a JSON value from a file. If this fails due to incomplete or invalid input, Nothing is returned.

The input file's content must consist solely of a JSON document, with no trailing data except for whitespace.

This function parses immediately, but defers conversion. See json for details.

encodeFile :: ToJSON a => FilePath -> a -> IO ()

Efficiently serialize a JSON value as a lazy ByteString and write it to a file.
