This not a full proof solution, but works great for NodeJS and planning to soon launch this for web JS.Īnd due to its simple tabular structure we can support this is other platforms too. However a quick, solution for that in NodeJS is to use bson-buffer At last const buf2 om ('Hello World') There are different accepted encoding when creating a Buffer: There are three separate functions allocated in the Buffer API to use and create new buffers. You can create an empty buffer by with a size of 10 bytes. But this should not be an issue if the object structure is know, and its unlikely that one may not know the object structure while dealing with cross platform stuff. There are different ways you can create a buffer in Node.js. MediumThumbnail: anotherJpegFileAsBuffer,Ĭonst photoSerializedAsBuffer = serialize(photo)Ĭonst deserialisedBack = deserialize(photo)īut it can get difficult when BSON types kick in. Its fastest and most space efficient among all the serializers of its kind. Its easy to use and built into the Node.js binary. Best way for pure NodeJS based environment Use "v8 Serialization API" Node JS v8 docs Performance wise JSON.stringify + om() is ok, but will not work out if the object contains ArrayBuffer, and if done, then very inefficient. When we are in NodeJS environment we have much better options than, om(JSON.stringify(data)). I'm not exactly sure what they are yet or if they apply but it looks like you can specify a schema in a file for all your messages and then serialize your JSON objects to that schema and have it return a buffer, which you can then deserialize using the same schema on the client/other server. Buffers only deal with binary data, and it can not be resizable. Buffer and array have some similarities, but the difference is array can be any type, and it can be resizable. Generally, Buffer refers to the particular memory location in memory. On server for reading buffer of Ĭonst readSecond = Boolean(result.readUInt8(2)) Ĭonst readFourth = result.toString('utf8', 5) Įdit #2: Was googling around and I think I might want something like protocol buffers. Buffers in Node.js: The Buffer class in Node.js is used to perform operations on raw binary data. On client for Ĭonst writeFirst = Buffer.allocUnsafe(2) Ĭonst writeSecond = Buffer.allocUnsafe(1) Ĭonst writeThird = Buffer.allocUnsafe(2) Ĭonst result = ncat() I guess my issue is just that it's too verbose and error-prone and I'm looking for a more concise and elegant way to do it, because this operation will be performed in many different places in my code. I'm looking at current solutions and it looks like I may have to just do a lot of concating, specifying byte offsets/lengths, converting from ints to booleans, etc.Įdit: Here's how I think you currently have to do it. Maybe something like this: object.toBuffer('int16', 'bool', 'int16', 'utf8') Īnd read it on the server something like this: var obj = buffer.read('int16', 'bool', 'int16', 'utf8') So, if I had the Javascript object of, I'd like to convert that to the buffer on the client right before sending it. I'm using Buffer on my node server and Buffer on my Javacript client.įor the purposes of saving bytes, I'm looking to send my data to the server through websockets as binary as opposed to JSON. ![]()
