dinky.js

JavaScript bindings for Derpibooru API

Installation

You can install this package from npm:

npm install dinky.js

Or with yarn:

yarn add dinky.js

Native ESM support

Dinky expose .mjs entry point, so you can use ESM natively in Node.js context using the --experimental-modules flag.

Usage

Dinky implements chainable API to build each request and all requests will return a Promise that resolves data taken from Derpibooru API.

1. The minimal example that will return an image by known ID:

import dinky from "dinky.js"

// The following request will return the 1th uploaded image from Derpibooru.
// Equivalent to https://derpibooru.org/images/0.json request
dinky().images().id(0).then(console.log)

2. Search for images by their tags using the .search() method:

import dinky from "dinky.js"

// You can specify tags right in the .search() method
// By default all requests will be sent to derpibooru.org, but you can
// manually set one of Derpibooru's host in constructor options if you need.
// The following example is equivalent of these requests:
// https://trixiebooru.org/search.json?q=artist:rainbow,safe&random_image=true
// ...and then this one:
// https://trixiebooru.org/images/<received image id>.json
dinky({url: "trixiebooru.org"}).search(["artist:rainbow", "safe"]).random()
  .then(console.log)

3. Since .search() method returns Search instance you can store it into variable for the further usage:

import dinky from "dinky.js"

(async function() {
  const search = dinky()
    .search(["scootaloo", "princess luna", "safe", "sleepless in ponyville"])
    .minScore(200)

  // Will search for random image with parameters from above
  await search.random()

  // ...and once more
  await search.random()
}()).catch(console.error)

4. Walking through the search results:

import dinky from "dinky.js"

(async function() {
  const search = dinky().search(["twilight sparkle"]).minScore(200)

  // Search class is thenable, so you don't have to call `.exec()` method
  // in async functions context.
  // This request will return search results from the first page
  await search

  await search.page(2)

  // Same thing for Images class:
  const images = dinky().images()

  await images.page(2)
}()).catch(console.error)

5. You can set a filter to use for requests:

import dinky from "dinky.js"

dinky({filter: 37430}).search(["dinky", "derpy hooves"]).then(console.log)

// You can also set per-request filter from .exec() method
dinky({filter: 37430}).search(["dinky", "derpy hooves"]).exec({filter: 100073})
  .then(console.log)

6. Search for "my:faves" images using a key taken from account page:

import dinky from "dinky.js"

dinky({key: "<your key here>"}).search(["trixie", "safe"]).faves()
  .then(console.log)

API

class Dinky

constructor([options]) -> {Dinky}

Creates a new instance of the Derpibooru API client

• {object} [options = {}] – client options
• {string} [options.url = "derpibooru.org"] - Derpibooru API hostname (you can set trixiebooru.org or derpibooru.org)
• {string} [options.key = undefined] – your personal API key taken from your account settings
• {number} [options.filter = undefined] – ID of a filter. The ID can be found on filters page

Instance methods

images() -> {Images}

Creates a request handler for /images.json

search([tags]) -> {Search}

Creates a request handler for /search.json. This method takes a list of tags

• {string | string[]} [tags = []] – a tag or a list of tags and returns Search instance

class Images > Request

constructor() -> {Images}

Creates a request handler for /images.json

Instance methods

id(id) -> {Promise<object>}

Returns an image with given ID

class Search > Request

constructor() -> {Search}

Creates a request handler for /search.json.

Instance methods

tags([list]) -> {Search}

Appends a tag or a list of tags to the current search request

• {string | string[]} [list = []] – a tag or a list of tags you want to append

faves() -> {Seatch}

Sets my:faves param to the search request.

Note that this method reques user's key.

watched() -> {Search}

Sets my:watched param to the search request.

Note that this method reques user's key.

upvotes() -> {Search}

Sets my:upvotes param to the search request.

Note that this method reques user's key.

limit(value) -> {Search}

Specifies how many images per page should API return

• {number} value – an amount of images you want to take. The value must be in range of 1 and 50.

minScore(value) -> {Search}

Sets the minimal score of requested images.

• {number} value – a value of minimal socre

maxScore(value) -> {Search}

Sets the maximal score of requested images

• {number} value – a value of maximal socre

random() -> {Promise<object>}

If been called, the API will return random image

class Request

constructor() -> {Request}

Creates a new request handler.

Instance methods

ascending() -> {Request}

Sets images ordering to ascending

descending() -> {Request}

Sets images ordering to descending

page(offset) -> {Request}

Sets the page offset

• {number} [offset = 1] – The page offset.

exec([options]) -> {Promise<object>}

Executes current request.

• {object} options – a set of options to use in request. They are have priority over the constructor options.
• {string} [options.key = undefined] – your personal API key taken from your account settings
• {number} [options.filter = undefined] – ID of a filter. The ID can be found on filters page

then(onFulfilled, onRejected) -> {Promise<object>}

This method takes up to two arguments: callback functions for the success and failure cases of the Promise. See Promise#then() documentation for more info.

catch(onRejected) -> {Promise<any>}

This method returns a Promise and deals with rejected cases only. See Promise#catch() documentation for more info.

class NetworkError > Error

constructor() -> {NetworkError}

This class can be used to check if network error was thrown.

Instance properties

response -> {Response}

Returns a Response object.

url -> {string}

status -> {number}

Contains the status code of the response (e.g., 200 for a success).
