{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Feature request: manually control type mapping","articleBody":"I would like to use this library in a node.js application that communicates with a msgpack API. Unfortunately, I need to be able to send messages that use specific data types for specific fields (e.g. `Array\u003cfixint\u003e`, `bin8`, ...) rather than have the library automatically choose/guess as described in\r\nhttps://github.com/msgpack/msgpack-node#type-mapping.\r\n\r\nHow hard would it be to incorporate this? For example, I'd like to be able to do this:\r\n\r\n```js\r\n// Binary data\r\nconst buff = getBufferFromSomewhere();\r\nmsgpack.pack(buff, { family: 'bin' }); // ==\u003e chooses `bin8`, `bin16` or `bin32` depending on buffer size\r\n\r\n// Force particular numeric type\r\nmsgpack.pack(123, { type: 'fixint' });\r\n\r\n// Specify custom type mapping when packing arrays\r\nconst a = [{ data: Math.PI, type: 'float64' }, { data: 3.14, type: 'float32' }];\r\nmsgpack.pack(a, {\r\n  interpret(item) {\r\n    return {\r\n      data: item.data,\r\n      type: item.type,\r\n      // alternatively:\r\n      family: item.family,\r\n    };\r\n  }\r\n});\r\n```\r\n","author":{"url":"https://github.com/jacobq","@type":"Person","name":"jacobq"},"datePublished":"2019-10-23T18:30:45.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/52/msgpack-node/issues/52"}
