[![Build Status](https://travis-ci.org/psibi/wai-slack-middleware.svg?branch=master)](https://travis-ci.org/psibi/wai-slack-middleware) [![Build Status](https://dev.azure.com/psibi2000/wai-slack-middleware/_apis/build/status/psibi.wai-slack-middleware?branchName=master)](https://dev.azure.com/psibi2000/wai-slack-middleware/_build/latest?definitionId=1?branchName=master)

A Slack middleware for [wai](https://www.stackage.org/package/wai)

Used for logging the request information into Slack from a WAI

application via middleware.

## Usage:

Settings are controlled via the type `SlackConfig`:

``` haskell

import Network.HTTP.Types.Status

let slackConfig = SlackConfig {

    webHookUrl = "https://hooks.slack.com/services/xxx/xxxxxxxx",

    httpManager = appHttpManager foundation,

    responseFilter = \resp -> status400 == responseStatus resp,

    requestFilter = \_ -> True

}

```

The above configuration will send slack notification for all 400 http

status code.

### Integrating with yesod scaffolding templates

Go to `Application.hs` and change the function `makeApplication` to

something like this:

``` haskell

makeApplication :: App -> IO Application

makeApplication foundation = do

  logWare <- makeLogWare foundation

  let slackConfig = SlackConfig {

                               webHookUrl = "https://hooks.slack.com/services/xxxx/xxxxxxx",

                               httpManager = appHttpManager foundation,

                               responseFilter = \resp -> status400 == responseStatus resp,

                               requestFilter = \_ -> True

                             }

  -- Create the WAI application and apply middlewares

  appPlain <- toWaiAppPlain foundation

  return $ slack slackConfig $ logWare $ defaultMiddlewaresNoLogging appPlain

```
