# HTTP Parser
|
||
|
|
|
||
|
|
This library parses HTTP protocol for requests and responses.
|
||
|
|
It was created to replace `http_parser.c` since calling C++ functions from JS is really slow in V8.
|
||
|
|
However, it is now primarily useful in having a more flexible/tolerant HTTP parser when dealing with legacy services that do not meet the strict HTTP parsing rules Node's parser follows.
|
||
|
|
|
||
|
|
This is packaged as a standalone npm module.
|
||
|
|
To use in node, monkeypatch HTTPParser.
|
||
|
|
|
||
|
|
```js
|
||
|
|
// Monkey patch before you require http for the first time.
|
||
|
|
process.binding('http_parser').HTTPParser = require('http-parser-js').HTTPParser;
|
||
|
|
|
||
|
|
var http = require('http');
|
||
|
|
// ...
|
||
|
|
```
|
||
|
|
|
||
|
|
## Testing
|
||
|
|
|
||
|
|
Simply run `npm test`.
|
||
|
|
The tests are copied from node and mscedex/io.js, with some modifcations.
|
||
|
|
|
||
|
|
## Status
|
||
|
|
|
||
|
|
This should now be usable in any node application, it now supports (nearly) everything `http_parser.c` does while still being tolerant with corrupted headers, and other kinds of malformed data.
|
||
|
|
|
||
|
|
### Node versions
|
||
|
|
|
||
|
|
`http-parser-js` should work via monkey-patching on Node v6-v11, and v13-14.
|
||
|
|
|
||
|
|
Node v12.x renamed the internal http parser, and did not expose it for monkey-patching, so to be able to monkey-patch on Node v12, you must run `node --http-parser=legacy file.js` to opt in to the old, monkey-patchable http_parser binding.
