Introduction #

This package implements the client APIs defined in the shadertoy_api package providing access to the Shadertoy REST and Site APIs.

Capabilities #

This package provides a number of operations through two types of clients:

REST APIs

  • Find shader by id
  • Find shaders from a list of id's
  • Query shaders by term, tags and sort them by name, likes, views, newness and by hotness (proportional to popularity and inversely proportional to lifetime). All the query results are paginated.
  • Find all shader ids
  • Find shaders ids by term, tags and sort them by name, likes, views, newness and by hotness (proportional to popularity and inversely proportional to lifetime). All the query results are paginated.

Site APIs

All the REST API features plus the following:

  • Login
  • Logout
  • Find user by id
  • Find shaders by user id
  • Query shaders by user id, tags and sort them by name, likes, views, newness and by hotness (proportional to popularity and inversely proportional to lifetime). All the query results are paginated as well.
  • Find comments by shader id
  • Find playlist by id.
  • Query shaders by playlist id. All the query results are paginated.
  • Query shader ids by playlist id. All the query results are paginated.
  • Download preview, i.e. the the shader thumbnails
  • Download media, any other media provided by the Shadertoy website

Getting Started #

Add this to your pubspec.yaml (or create it):

dependencies:
    shadertoy_client: ^1.0.0-dev.8

Run the following command to install dependencies:

pub install

Optionally use the following command to run the tests:

pub run test

Finally, to start developing import the library:

import 'package:shadertoy_client/shadertoy_client.dart';

Usage #

You can use this library with one of the following classes:

  • ShadertoyWSClient, for the REST API. This client can only provide shaders made available with the public+api privacy settings
  • ShadertoySiteClient for the Site API. This client provides all the shaders currently available in the Shadertoy website
  • ShadertoyHybridClient, which allows the user to constrain the requests to shaders with public+api privacy settings while complementing the base REST API with some additional operations only available in the Site API.

ShadertoyWSClient #

Note: replace apiKey with the API key obtained in your user apps page

Query a shader by id

    var apiKey = '<apiKey>';
    var client = ShadertoyWSClient.build(apiKey);
    var fsr = await client.findShaderById('3lsSzf');
    if (fsr.ok) {
        print('${fsr?.shader?.info?.id}');
        print('\tName: ${fsr?.shader?.info?.name}');
        print('\tUserName: ${fsr?.shader?.info?.userId}');
        print('\tDate: ${fsr?.shader?.info?.date}');
        print('\tDescription: ${fsr?.shader?.info?.description}');
        print('\tViews: ${fsr?.shader?.info?.views}');
        print('\tLikes: ${fsr?.shader?.info?.likes}');
        print('\tPublish Status: ${fsr?.shader?.info?.publishStatus.toString().split('.').last}');
        print('\tTags: ${fsr?.shader?.info?.tags?.join(',')}');
        print('\tFlags: ${fsr?.shader?.info?.flags}');
        print('\tLiked: ${fsr?.shader?.info?.hasLiked}');
        print('\tRender Passes: ${fsr?.shader?.renderPasses?.length}');
        fsr?.shader?.renderPasses?.forEach((rp) => print('\t\t${rp?.name} has ${rp?.inputs?.length} input(s) and ${rp?.outputs?.length} output(s)'));
    } else {
        print('Error: ${fsr.error.message}');
    }

Output:

Query shaders by term:

    var apiKey = '<apiKey>';
    var client = ShadertoyWSClient.build(apiKey);
    var fsr = await ws.findShaders(term: 'elevated');
    if (fsr.ok) {
        print('${fsr.total} shader id(s) found');
        response?.shaders?.forEach((sh) {
            print('${sh?.shader?.info?.name}');
        });
    } else {
        print('Error: ${fsr.error.message}');
    }

and the output, with the returned shader id's matching the term:

10 shader id(s) found
MdX3Rr 
MdBGzG 
lslBz7 
MtK3Wc 
XlXGzS 
XdKGW1 
ltd3Wl

ShadertoySiteClient #

Note: replace user and password, with the user credentials, where applicable

Find a shader by id using a anonymous site client

  var client = ShadertoySiteClient.build();

  var fsr = await ws.findShaderById('3lsSzf');
  if (fsr.ok) {
    print('${fsr?.shader?.info?.id}');
    print('\tName: ${fsr?.shader?.info?.name}');
    print('\tUserName: ${fsr?.shader?.info?.userId}');
    print('\tDate: ${fsr?.shader?.info?.date}');
    print('\tDescription: ${fsr?.shader?.info?.description}');
    print('\tViews: ${fsr?.shader?.info?.views}');
    print('\tLikes: ${fsr?.shader?.info?.likes}');
    print('\tPublish Status: ${fsr?.shader?.info?.publishStatus.toString().split('.').last}');
    print('\tTags: ${fsr?.shader?.info?.tags?.join(',')}');
    print('\tFlags: ${fsr?.shader?.info?.flags}');
    print('\tLiked: ${fsr?.shader?.info?.hasLiked}');
    print('\tRender Passes: ${fsr?.shader?.renderPasses?.length}');
    sr?.shader?.renderPasses?.forEach((rp) => print('\t\t${rp?.name} has ${rp?.inputs?.length} input(s) and ${rp?.outputs?.length} output(s)'));
  } else {
    print('Error: ${fsr.error.message}');
  }

Output:

Anonymous usage of the site client versus logged in usage


  var client =
      ShadertoySiteClient.build(user: '<user>', password: '<password>');

  print('Anonymous');
  var fsr = await client.findShaderById('3lsSzf');
  print('${fsr?.shader?.info?.id}');
  print('\tName: ${fsr?.shader?.info?.name}');
  print('\tLiked: ${fsr?.shader?.info?.hasLiked}');

  await site.login();

  print('Logged In');
  site.cookies.forEach((c) => print('${c.name}=${c.value}'));
  fsr = await client.findShaderById('3lsSzf');
  print('${fsr?.shader?.info?.id}');
  print('\tName: ${fsr?.shader?.info?.name}');
  print('\tLiked: ${fsr?.shader?.info?.hasLiked}');

Notice that the liked flag flips from false to true after the login

  } else {
    print('Error: ${fcr.error.message}');
  }
