Error states are a second class citizen in building UIs. One of the reasons is the developers building it don't get error states often from their APIs. What if we change that? 6 | 7 | ## How? 8 | 9 | rest-in-chaos is a command line utility that spawns proxy server, a really shitty one at that. Every request made to the rest-in-chaos server is either proxied to the passed URL, or returns an error response. It's completely random. It's chaos. 10 | 11 | ## Installation 12 | 13 | Run the following command 14 | 15 | ``` 16 | go get -u github.com/nshntarora/rest-in-chaos 17 | ``` 18 | 19 | The binary will now be available in the `bin` directory in your `GOPATH` 20 | 21 | ## Usage 22 | 23 | ``` 24 | rest-in-chaos <> 25 | ``` 26 | 27 | The server will be running on the port **24267** 28 | 29 | ## Example 30 | 31 | ``` 32 | rest-in-chaos http://localhost:3000 33 | ``` 34 | 35 | Any request to localhost:24267 will be proxied to localhost:3000, with the exception of some requests chosen at random. 36 | -------------------------------------------------------------------------------- /cmd/root.go: -------------------------------------------------------------------------------- 1 | /* 2 | Copyright © 2019 NAME HERE 3 | 4 | Licensed under the Apache License, Version 2.0 (the "License"); 5 | you may not use this file except in compliance with the License. 6 | You may obtain a copy of the License at 7 | 8 | http://www.apache.org/licenses/LICENSE-2.0 9 | 10 | Unless required by applicable law or agreed to in writing, software 11 | distributed under the License is distributed on an "AS IS" BASIS, 12 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 13 | See the License for the specific language governing permissions and 14 | limitations under the License. 15 | */ 16 | package cmd 17 | 18 | import ( 19 | "errors" 20 | "fmt" 21 | "os" 22 | "time" 23 | 24 | "github.com/spf13/cobra" 25 | 26 | "math/rand" 27 | "net/http" 28 | "net/url" 29 | 30 | echo "github.com/labstack/echo" 31 | distuv "gonum.org/v1/gonum/stat/distuv" 32 | 33 | middleware "github.com/labstack/echo/middleware" 34 | homedir "github.com/mitchellh/go-homedir" 35 | "github.com/spf13/viper" 36 | ) 37 | 38 | var poissonGenerator distuv.Poisson 39 | 40 | var cfgFile string 41 | 42 | // rootCmd represents the base command when called without any subcommands 43 | var rootCmd = &cobra.Command{ 44 | Use: "rest-in-chaos", 45 | Short: "add unreliability to any HTTP service", 46 | Long: `rest-in-chaos is an HTTP proxy that randomly fails any request you make to its server, and lets the remaining ones go. 47 | `, 48 | Args: func(cmd *cobra.Command, args []string) error { 49 | if len(args) < 1 { 50 | return errors.New("URL argument required.
