Usage

Syntax

piwo [METHOD] [URL] [BODY]

METHOD: must be uppercase and they can be GET, POST, PUT, PATCH and DELETE. If you don’t send a method Piwo will make a GET (default) request.

URL: you can omit the protocol in the url (http or https).

BODY: the body is JSON (default).

Make a GET request

piwo GET https://api.github.com/

A shortest way:

piwo api.github.com

Make a POST, PATCH or PUT request sending a body/JSON

piwo POST localhost:3000/send_your_foo foo=bar

If you need to send a value with spaces, use quotes.

piwo PATCH localhost:3000/update_your_foo foo="this is my bar"

You can also send multiple values, just separing with spaces

piwo POST localhost:3000/signup username=foo password=bar

Make a DELETE request

piwo DELETE localhost:3000/your_foo/remove

Sendin a property with object value type

piwo POST localhost:3000/cli/registry cli={name=piwo description="your friendly HTTP cli tool"}

Sending a property with array value type

piwo PATCH localhost:3000/cli/piwo tags=[typescript deno cli http]

Send a form/body

You just need to add the –form flag

piwo --form POST localhost:3000/ search_query="foo bar"

Run command usage

Create a request.json file in your project. The keys that piwo are expecting from the file are names or aliases that can be called in the console, and this aliases should have as value a config similar to the fetch API considering that it is not possible to execute javascript code in a json file

Example

{
  "github": {
    "method": "GET",
    "url": "https://api.github.com"
  }
}

Run the next code in your command-line:

piwo run github

Send a JSON

{
  "new-task": {
    "method": "POST",
    "url": "http://localhost:8080/task/",
    "headers": {
      "Content-Type": "application/json"
    },
    "body": {
      "name": "read a json file",
      "description": "piwo should read a json file to simplify a request"
    }
  }
}
piwo run new-task

Send a Form

{
  "foo:form": {
    "method": "POST",
    "url": "http://localhost:8080/",
    "headers": {
      "Content-Type": "application/x-www-form-urlencoded"
    },
    "body": {
      "foo": "bar"
    }
  }
}
piwo run foo:form

Content-Type value can be multipart/form-data;

Some nice tips

How URL argument works

When you’re doing a request you can omit the protocol, Piwo will make a request with https, if get not response then will try with the http protocol and then will output the response of the server or a msg that couldn’t connect when no server is found.

When you send the URL with protocol Piwo will not check the other protocol.

If you’re sure that the server is on http protocol, we recommend you to pass the protocol in the url, is faster because piwo will do a direct request with the procotol and will not check the https procotol.

If the url is a localhost, then will first try with HTTP.
