Is a binary JSON javascript library available for browsers?
提问by Lorenz Lo Sauer
In order for efficient server side parsing I am looking into a BSON solution directly for the browser javascript environment. The idea is to utilize the entire ASCII space by means of binary websockets. Any suggestions?

(Any nodejs suggestions are welcome as well)

This might be incomplete but the goal of the project line up with what you want: https://github.com/muhmi/javascript-bsonIt doesn't look like that encodes directly to typed arrays which would be the most useful for sending over WebSocket.
这可能不完整，但项目的目标与您想要的一致：https: //github.com/muhmi/javascript-bson它看起来不像直接编码到类型化数组，这对发送最有用通过 WebSocket。

For what it's worth, it appears that the MongoDB team now have a supported Javascript BSON project:
就其价值而言，MongoDB 团队现在似乎有一个受支持的 Javascript BSON 项目：
https://github.com/mongodb/js-bson
https://github.com/mongodb/js-bson
I'm no expert with the library, but the project claims to work in both Node and the browser. Below is a modified sample from their site:
我不是该库的专家，但该项目声称可以在 Node 和浏览器中运行。以下是来自他们网站的修改后的示例：
<head>
<!-- Originally https://raw.github.com/mongodb/js-bson/master/browser_build/bson.js -->
<!-- But downloaded and hosted locally -->
<script src="./bson.js"></script>
</head>
<body onload="start();">
<script>
function start() {
var BSON = bson().BSON;
var Long = bson().Long;
var doc = {
oid: bson().ObjectID(),
long: Long.fromNumber(100),
date: new Date(),
string: "js-bson sample",
obj: {
string: "Object within an object"
}
}
console.log("doc %o", doc);
// Serialize a document
var data = BSON.serialize(doc, false, true, false);
console.log("data %o", data);
// De serialize it again
var doc_2 = BSON.deserialize(data);
console.log("doc_2 %o", doc_2);
}
</script>
</body>

Here in 2019 modern browsers already have embedded the functions:
在 2019 年，现代浏览器已经嵌入了以下功能：
btoa("string to be coded on base64 format")
atob("base64 string to be uncoded")As you can see here: https://caniuse.com/#search=btoaAll browsers listed have this feature.
正如您在此处看到的：https: //caniuse.com/#search=btoa列出的所有浏览器都具有此功能。
