shadertoy #






Overview #
The shadertoy library provides the support to interact with the Shadertoy site and REST API's defining the data model and contracts to query and store the shaders, comments, users, playlists and website media.
Features #

📌 REST API - Supports all the Shadertoy REST APIs (as defined here)
🌐 Site API - Supports scrapping of data directly from the Shadertoy site allowing the retrieval of users query comments, users, playlists and website media.
🔗 Hybrid API - Respects public+api privacy settings of the shaders while providing support for additional operations, namely the retrieval of shader comments, user, playlists and website media
➿ Extensible - Plug novel storage and client implementations reusing the APIs and entities defined on the shadertoy package

Client Implementations #
The following client implementations are available



Package
Pub
Description




shadertoy_client

HTTP client to the Shadertoy REST and Site API using the dio package



Storage Implementations #
The following storage implementations are available



Package
Pub
Description




shadertoy_sqlite

A Sqlite storage implementation using the drift package



Getting Started #
Select one of the client or storage implementations (or both) and add the package to your pubspec.yaml replacing x.x.x with the latest version of the implementation. The example below uses the shadertoy_client package which implements the shadertoy REST and site APIs:
dependencies:
shadertoy_client: ^x.x.x

Run the following command to install dependencies:
dart pub get

Finally, to start developing import the library:
import 'package:shadertoy_client/shadertoy_client.dart';

Usage #
Instantiate a ShadertoyClient implementation, for example the one provided by the package shadertoy_client to access the client API:
// Created a client to the REST API using the API key `apiKey`
final client = newShadertoyWSClient(apiKey);
copied to clipboard
and execute one of the methods provided, for example to obtain a shader by id execute the findShaderById method providing the id of the shader as parameter:
// Execute the call to the REST API
final result = await client.findShaderById('Mt3XW8');
// Check if there's errors
if (result.ok) {
// Print the shader name if not
print(fsr?.shader.name);
} else {
// Prints the error message otherwise
print('Error: ${result.error.message}')
}

In alternative instantiate a ShadertoyExtendedClient implementation, for example the one provided by the package shadertoy_client, to access the site API:
final client = newShadertoySiteClient();
copied to clipboard
and execute one of the methods provided, for example to obtain the shader comments by shader id execute the findCommentsByShaderId method providing the id of the shader as parameter:
// Execute the call to the site API
final result = await client.findCommentsByShaderId('MdX3Rr');
// Check if there's errors
if (result.ok) {
// Prints the shader comments
print(jsonEncode(result.comments));
} else {
// Prints the error message otherwise
print('Error: ${fsr.error.message}')
}

As mentioned in the feature list, to (optionally) respect the shader privacy constraints but still benefit from a larger set of operations (some of them available only through the site API), the hybrid API can be used. Start by instancianting a suitable hybrid API implementation, for example the one provided by the shadertoy_client package:
// Creates a hybrid client using the REST API key `apiKey`
// This effectivly filters the shaders and provides only the ones respecting the shader
// `public+api` privacy settings
final client = newShadertoyHybridClient(apiKey: apiKey);
copied to clipboard
and execute one of the methods provided, for example to obtain a shader by id execute findShaderById providing the id of the shader as parameter:
// Execute the call to the hybrid API
final result = await client.findShaderById('3lsSzf');
// Check if there's errors
if (result.ok) {
// Prints the shader id
print(result.shader?.info.id);
} else {
// Prints the error message otherwise
print('Error: ${result.error.message}')
}

To create a database providing the same set of read operations as the previous APIs but also the ability to save shaders as well as other entities a ShadertoyStore contract is also provided. To make use of the ShadertoyStore a suitable implementation should be provided, for example, the one available on shadertoy_sqlite:
// Creates a new store with an in-memory executor
final store = newShadertoySqliteStore(memoryExecutor());
copied to clipboard
and execute one of the operations, for example storing a user:
// Create a user
final user = User(id: 'UzZ0Z1', about: 'About user 1', memberSince: DateTime.now());
// Save the user
final result = await store.saveUser(user);
// Check if there's errors
if (result.ok) {
// Prints a success message
print('Shader stored');
} else {
// Prints the error message otherwise
print('Error: ${response.error.message}')
}

APIs #

The client API targetting the REST interfaces defined in the Shadertoy howto which allow the user to browse shaders available with public+api privacy settings. Note that the number of operations available with this API are limited albeit enough for simple browsing usage. To start using an API key needs to be obtained through a properly registered user on the apps page of the user section on the Shadertoy website.
The extended client API provides access to the same methods as the previous API but adds features that are only available on the site API, namely, the support to fetch users, playlists, shader comments and website media. Note that the shaders returned by this API are not constrained by the public+api privacy settings.
The hybrid API complements the basic client API allowing the base REST API client to benefit from the additional features os the extended client API still (optionally) respecting the public+api constrains imposed by the shader creators. In a nutshell it allows the REST API users to access user, shader comments and website media of the public+api shaders if configured with an API key
The store API, defines contracts supporting the creation of data stores thus providing a way to work offline with the downloaded shaders instead of relying on the Shadertoy APIs. It supports all the methods as the previous API plus the storage primitives.
