This is a technical description of the blueprint string format, used to share blueprints with other users.
A blueprint string is a JSON representation of the blueprint, compressed with zlib deflate using compression level 9 and then encoded using base64 with a version byte in front of the encoded string. The version byte is currently 0 (for all Factorio versions through 1.0).
So to get the JSON representation of a blueprint from a blueprint string, skip the first byte, base64 decode the string, and finally decompress using zlib inflate.
Json representation of a blueprint/blueprint book
The json representation of a blueprint or blueprint book is one large object inside another "wrapping" object, its key inside that object is either blueprint or blueprint-book.
