Show HN: httpinvoke – js HTTP client - easy progress events, binary files, etc.
- dreamdu5t 13y agoHow does this compare with superagent?
- tahu 13y agohttpinvoke and superagent differences: * superagent has a "fluent" API, httpinvoke is a plain function, with an options object and with Node.js callbacks and/or promises. * superagent is not easy to use with binary uploads/downloads * superagent does not give you an abstraction over progress events * httpinvoke does not build query strings * httpinvoke gives you raw multipart/form-data responses, does not parse them Other aspects are comparable (file size, Node.js and browser support, etc).
- tahu 13y agoExisting libraries - like jquery, reqwest and superagent - had no easy support for promises, binary files and progress events, did not support a wide range of browser versions, did not nicely treat HTTP status codes. So I made this.
- antihero 13y agoWhat happens if you use this with a different promise library (e.g. bluebird)? I'm rather confused - if everything implements it's own promises, does it "just work" or do we have to worry about it all getting rather messy?
- tahu 13y agoHi, thanks for the questions, sorry for the late reply.. httpinvoke fully implements Promises/A+ specification. The spec is very short and easily implementable. The implementation in httpinvoke takes only 568bytes when minified (check it out!). So the answer is, if you use httpinvoke with a different promise library, it will work, unless the library really is at odds with Promises/A+ specification. Which is unlikely, because all the major promises libraries support it, even if they do not indicate that in their documentation. httpinvoke only contact with the external promise (which it can only get when onFulfill or onReject returns one) is the .then method here [1].

- antihero 13y agoSay, hypothetically (I haven't done any tests or anything) that Bluebird was faster than the included promise specification, is there some sort of dependency injection to replace it, seeing as it's a spec?
- tahu 13y agoWithout a doubt Bluebird, When.js, Q, then/promise and others are faster. The implementation in httpinvoke is optimized for code size. The other reason for current solution is that the specification for creating and resolving promises [1] is not yet published. Having a Promise object in global scope, as exported by Q, Bluebird and then/promise, is not enough. There is no uniform way to hack into these implementations and use their promises resolver. But when resolvers-spec is available, httpinvoke will definitely check for already loaded promises library and reuse it.

- nevf 13y agoAre there any plans to support gzip in GET the way http-get does?
- tahu 13y agoThank you! Just implemented gzip support and released 1.0.4.
- Oleg2tor 13y agoSimple question - how to send "application/x-www-form-urlencoded" with inputs? Why documentation miss basic things like this?
