tbrand / router.cr Goto Github PK

The Crystal community has somewhat decided to use crystal as the language's topic.

To avoid fragmentation in the community, please drop crystallang and crystal-language topics, that only have ~12 or ~28 repositories at the moment. We're sticking to crystal, instead.

Any contributor can change it from the repo's homepage.

See crystal-lang/crystal#4241 for more context.

Thank you very much :)

Hi @tbrand,

I can see on README that version is pin to 0.2.2

However, the last version is 0.2.4

Regards,

Is there an example for how to retrieve POST params from an HTML form? router.cr seems to ignore GET and POST params, only providing the params available in the URL (e.g., '/posts/:post_id').

Am I missing something? Or is that a limitation of this router framework?

Hello,

I've checked your project and it either:

• Has specs failed with the latest Crystal (0.26.1)
• Has no any specs to run so it cannot be validated to be up to date
• Has the latest commit dated more than a year ago

Your project is in Awesome Crystal list, so I'd like to ask if the project maintained?

I'll initiate a PR to remove your project from the list if you don't respond positively within 7 days.

I'm sorry if I'm wrong, because I've been checking many shards with automated script.

Thanks,
Vlad.

This makes shards think it has to fetch the repo on every build. To fix this the git tag should match the version in shards.yml

Hi @tbrand,

It could be useful to add some path constraint to routes, I mean adding a regex (or else to allow / or not some pathes).

For example, adding /user/:id(\\d+), create a route for /user/0, /user/1... but not/user/a`

WDYT ?

PS : This example is taken from kitura

crystal-community/crystal-libraries-needed#8

What is best way to separate route in different class. I'm thinking to create modular app and each has its own route declaration.

I don't want to step on your toes here but how about writing some more descriptive commit messages in the future? :) "Fix" doesn't tell me much. :P

I think nobody use this...

Hello, @tbrand !

Error occuried when i'am trying shards install

shard.yml

name: test
version: 0.1.0

authors:
  - test <[email protected]>

targets:
  test:
    db: src/test-db.cr
    api: src/test-api.cr

dependencies:
  router:
    github: tbrand/router.cr

license: MIT

Currently if the route not found it doesn't touch the default response and returns 200 status code.

When a server is accessed with a path, it idiomatically triggers something a.k.a. an action happens. My proposal is to replace API (alias API = Proc(HTTP::Server::Context, Hash(String, String)) with Action.

Given the route specification /:id I should be able to request /12345?param=value and have
the router break down the params as {"id": "12345", "param": "value"}, instead the parameters are given as {"id": "12345?param=value"}.

As addition to use block handler, it would be nice to add method handler or class handler to make the router code cleaner and follow separation of concern.

# block handler
get "/" do |context, params|
 context.response.print "Hello router.cr!"
 context
end

# method handler
get "/" home
post "/user" add_user

def home(context, params) : HTTP::Server::Context
  context.response.print "Hello router.cr!"
  context
end

# class handler
article = Article.new
get "/article/:id" article.get 
put "/article/:id" article.update 

class Article
  def get(context, params)
    context.response.print "Hello router.cr!"
    context
  end
end

You should be able to combine multiple handlers that can handle different routes (e.g. a handler for /favicon.ico or a monitoring API, etc...)

Route::RouteHandler#call(context) raises an exception when it can't route rather than "passing the torch" to the next handler. This makes combining routers impossible.

Is it possible to improve performance if the router could convert string to bytes using to_slice?

From the benchmark, to_slice would cost <4 nanoseconds and efficient to compare using ==

Range  17.51M ( 57.11ns) (±10.77%)  32 B/op  14.44× slower
Slice     252.8M (  3.96ns) (± 5.81%)   0 B/op        fastest

Range:
key[0..-2]

Slice:
(key.to_slice)[0,key.size-2]

Hi @tbrand, I like router.cr as middleware.

Would be possible to add router.cr to https://github.com/TechEmpower/FrameworkBenchmarks ?

TFB have three categories:

1. Middlewares, like puma, nginx
2. Micro frameworks like Kemal, Sinatra, Flask
3. Full frameworks like Phoenix, Django, Amber.

I think router.cr can compete in the first category, What do you think?
