Update readme with simple tutorial #2

artemredkin · 2019-04-08T14:49:45Z

Motivation:

Every library should have a tutorial

Modifications:

Added README.md

Result:

Users will have a tutorial to get started with this library

tomerd · 2019-04-09T21:16:50Z

nice progress!

=> one small comment is we generally follow a template for commit messages and PRs, see

=> check out the readme on swift-log and swift-metrics. they roughly have the following sections:

overview
tl;dr / getting started guide
detailed design / architecture with examples

README.md

+
+```swift
+dependencies: [
+    .package(url: "https://github.com/swift-server/swift-nio-http-client.git", from: "1.0.0")


did we tag yet? if not, maybe be more explicit about that, see swift-log and swift-metrics READMEs

replaced with .branch("master")

+## Status
+
+This library provides the following:
+1. Async single request methods


"single request methods" is a bit unclear, rephrase?

fixed, do you thinks its better now?

+1. Async single request methods
+2. Simple follow-redirect support (cookie headers are dropped)
+3. Body download streaming


Streaming body download

fixed, thanks

+### Request-Response API
+The code snippet below illustrates how to make a simple GET request to a remote server:
+
+```import HTTPClient


fixed here and in all other blocks

tomerd · 2019-04-09T21:21:29Z

README.md

+```import HTTPClient
+
+let httpClient = HTTPClient(eventLoopGroupProvider: .createNew)
+let response = try httpClient.get(url: "https://swift.org").wait()


personally i dont love guiding users to use wait, and where we do we should make a note that this is not the proper way to do things

good point! re-wrote example

tomerd · 2019-04-09T21:22:57Z

README.md

+```
+In this case shutdown of the client is not neccecary.
+
+Library provides methods for most HTTP-methods. In case you need to have more control over the method, or you want to add headers or body, use ```HTTPRequest``` struct:


Library provides methods for most HTTP-methods -> Most common HTTP methods are supported out of the box

done, thanks!

format to be more readable

re-formatted, is it better now?

README.md

+```
+
+### Streaming
+In case greater control over body processing is needed or you want to process HTTP Reponse body in a streaming manner, following delegate protocol could be used (example shows how to count bytes in response body without copiying it to the memory):


When dealing with larger amount of data, it's critical to steam the response body instead of aggregating it-memory. Handling a response stream is done using a delegate protocol. The following example demonstrates how to count the number of bytes in a streaming response body:

I've re-structured it a bit, what do you think? Should I add more info about architecture?

unrelated to this PR but i would rename connectTimeout to connect or connection and readTimeout to read since these are properties of a Timeout object

nice work @artemredkin couple of more small comments. +1 to merge after they are addressed

Should I add more info about architecture?

i think that's a good idea, but we can do a follow up PR to control scope

more tests

* Proposal to fix #362. Allows user to setup a channel with a client certificate and key but still use default root certificates. * fix #362. Respect PR critique. make roots_pem() public. Update Channel init. * fix #362: make roots_pem() return force-unwrapped String. Change Channel API accordingly. * Remove an obsolete comment. * Minor whitespace tweak #1 * Minor whitespace tweak #2

Update readme with simple tutorial
