It is not only writing code. Contributions like discussing solutions in open issues are easily as valuable as contributing code as we can then find the best solution with the perspective of multiple people. 3 | 4 | ## Bugs and feature requests 5 | If you find any bugs in the project or have requests for features, then please [Open a new Issue](https://github.com/KristofferStrube/Blazor.FileSystem/issues/new). 6 | 7 | ## Contributing Code and Samples 8 | Before you contribute to the project, you will need to get confirmation from the library author that the contribution is welcome. 9 | This can help align the scope of the contribution so that you and the author agree on the solution and how you ensure the change is maintainable with the existing users in mind. 10 | Once you are ready to start coding try to follow these code guidelines: 11 | - Make a fork of the current `main` branch. 12 | - Follow the existing coding conventions used in the project. This includes tab style, naming conventions, etc. 13 | - If your contribution is a new feature, try to add a demo that demonstrates how this will be used in the sample project. 14 | - Any code or sample you share as a part of the resulting Pull Request should fall under the MIT license agreement. 15 | - You don't need to update the version number of the project as the maintainer will do this when making the next release after the Pull Request has been merged. 16 | - Keep your Pull Request to the point. I.e., if your Pull Request is related to fixing a bug then try not to touch any other files than the ones related to that issue as this will make the chance of the PR being merged without change requests more likely. 17 | 18 | ## Submitting a Pull Request 19 | If you don't know what a pull request is, read this article: https://help.github.com/articles/using-pull-requests. Make sure the repository can be built and that the related sample project still works as intended. It is also a good idea to familiarize yourself with the project workflow and our coding conventions. 20 | 21 | ## Ensuring that your contribution will be accepted 22 | You might also read these two blog posts on contributing code: [Open Source Contribution Etiquette](http://tirania.org/blog/archive/2010/Dec-31.html) by Miguel de Icaza and [Don't "Push" Your Pull Requests](https://www.igvita.com/2011/12/19/dont-push-your-pull-requests/) by Ilya Grigorik. These blog posts highlight good open-source collaboration etiquette and help align expectations between you and us. 23 | -------------------------------------------------------------------------------- /LICENSE: -------------------------------------------------------------------------------- 1 | MIT License 2 | 3 | Copyright (c) 2023 Kristoffer Strube 4 | 5 | Permission is hereby granted, free of charge, to any person obtaining a copy 6 | of this software and associated documentation files (the "Software"), to deal 7 | in the Software without restriction, including without limitation the rights 8 | to use, copy, modify, merge, publish, distribute, sublicense, and/or sell 9 | copies of the Software, and to permit persons to whom the Software is 10 | furnished to do so, subject to the following conditions: 11 | 12 | The above copyright notice and this permission notice shall be included in all 13 | copies or substantial portions of the Software. 14 | 15 | THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR 16 | IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, 17 | FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

It also enables access to the **origin private file system** which is a virtual sandboxed file system. This project implements a wrapper around the API for Blazor so that we can easily and safely interact with it from Blazor. 11 | 12 | # Demo 13 | The sample project can be demoed at https://kristofferstrube.github.io/Blazor.FileSystem/ 14 | 15 | On each page you can find the corresponding code for the example in the top right corner. 16 | 17 | On the [API Coverage Status](https://kristofferstrube.github.io/Blazor.FileSystem/Status) you can see how much of the WebIDL specs this wrapper has covered. 18 | 19 | # Getting Started 20 | ## Prerequisites 21 | You need to install .NET 7.0 or newer to use the library. 22 | 23 | [Download .NET 7](https://dotnet.microsoft.com/download/dotnet/7.0) 24 | 25 | ## Installation 26 | You can install the package via Nuget with the Package Manager in your IDE or alternatively using the command line: 27 | ```bash 28 | dotnet add package KristofferStrube.Blazor.FileSystem 29 | ``` 30 | 31 | # Usage 32 | The package can be used in Blazor WebAssembly and Blazor Server projects. (Note that streaming of big files is not supported in Blazor Server due to bandwidth problems.) 33 | ## Import 34 | You need to reference the package in order to use it in your pages. This can be done in `_Import.razor` by adding the following. 35 | ```razor 36 | @using KristofferStrube.Blazor.FileSystem 37 | ``` 38 | ## Add to service collection 39 | The library has one service which is the `IStorageManagerService` which can be used to get access to the **origin private file system**. An easy way to make the service available in all your pages is by registering it in the `IServiceCollection` so that it can be dependency injected in the pages that need it. This is done in `Program.cs` by adding the following before you build the host and run it. 40 | ```csharp 41 | var builder = WebAssemblyHostBuilder.CreateDefault(args); 42 | builder.RootComponents.Add("#app"); 43 | builder.RootComponents.Add("head::after"); 44 | 45 | // Other services are added. 46 | 47 | builder.Services.AddStorageManagerService(); 48 | 49 | await builder.Build().RunAsync(); 50 | ``` 51 | ## Inject in page 52 | Then the service can be injected in a page like so: 53 | ```razor 54 | @inject IStorageManagerService StorageManagerService; 55 | ``` 56 | Then you can use `IStorageManagerService` to get a directory handle for the **origin private file system** and read/create a file in it like this: 57 | ```razor 58 | 59 | 60 | @code { 61 | private async Task OpenAndReadFile() 62 | { 63 | FileSystemDirectoryHandle directoryHandle = await StorageManagerService.GetOriginPrivateDirectoryAsync(); 64 | FileSystemFileHandle fileHandle = await directoryHandle.GetFileHandleAsync("file.txt", new() { Create = true }); 65 | FileAPI.File file = await fileHandle.GetFileAsync(); 66 | // Do something with the file. 67 | } 68 | } 69 | ``` 70 | 71 | The counterpart to getting a `File` via the `GetFileAsync()` method is getting a `FileSystemWritableFileStream` via the `CreateWritableAsync()` method which can be used to write to the file referenced with the `FileSystemFileHandle` like this: 72 | ```csharp 73 | FileSystemFileHandle fileHandle; // Some file handle 74 | FileSystemWritableFileStream writable = await fileHandle.CreateWritableAsync(); 75 | await writable.WriteAsync("some text"); 76 | await writable.CloseAsync(); 77 | ``` 78 | You need to close the `FileSystemWritableFileStream` to commit the written text. You can either do so explicitly as seen above or you can use it in a using statement like this: 79 | ```csharp 80 | FileSystemFileHandle fileHandle; // Some file handle 81 | await using FileSystemWritableFileStream writable = await fileHandle.CreateWritableAsync(); 82 | await writable.WriteAsync(new byte[] { 0, 1, 2, 3, 4, 5 }); 83 | ``` 84 | This will automatically await the close when you get to the end of the current scope. 85 | 86 | # Issues 87 | Feel free to open issues on the repository if you find any errors with the package or have wishes for features. 88 | 89 | # Related repositories 90 | This project uses the *Blazor.FileAPI* package to return a rich `File` from the `GetFileAsync` method on a `FileSystemFileHandle` and when writing a `Blob` to a `FileSystemWritableFileSystem`. 91 | - https://github.com/KristofferStrube/Blazor.FileAPI 92 | 93 | This project is used in the *Blazor.FileSystemAccess* package as a basis for the file handles that it uses in its methods and extends on. 94 | - https://github.com/KristofferStrube/Blazor.FileSystemAccess 95 | 96 | # Related articles 97 | This repository was build with inspiration and help from the following series of articles: 98 | 99 | - [Wrapping JavaScript libraries in Blazor WebAssembly/WASM](https://blog.elmah.io/wrapping-javascript-libraries-in-blazor-webassembly-wasm/) 100 | - [Call anonymous C# functions from JS in Blazor WASM](https://blog.elmah.io/call-anonymous-c-functions-from-js-in-blazor-wasm/) 101 | - [Using JS Object References in Blazor WASM to wrap JS libraries](https://blog.elmah.io/using-js-object-references-in-blazor-wasm-to-wrap-js-libraries/) 102 | - [Blazor WASM 404 error and fix for GitHub Pages](https://blog.elmah.io/blazor-wasm-404-error-and-fix-for-github-pages/) 103 | - [How to fix Blazor WASM base path problems](https://blog.elmah.io/how-to-fix-blazor-wasm-base-path-problems/) 104 | -------------------------------------------------------------------------------- /docs/icon.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/KristofferStrube/Blazor.FileSystem/718d8d36c44a7c61d994ff19a54b98ce4386a29a/docs/icon.png -------------------------------------------------------------------------------- /samples/KristofferStrube.Blazor.FileSystem.WasmExample.Benchmarks/BenchmarkRenderer.cs: -------------------------------------------------------------------------------- 1 | using Microsoft.AspNetCore.Components.RenderTree; 2 | using Microsoft.AspNetCore.Components; 3 | using Microsoft.Extensions.DependencyInjection; 4 | using Microsoft.Extensions.Logging.Abstractions; 5 | using Microsoft.Extensions.Logging; 6 | 7 | namespace KristofferStrube.Blazor.FileSystem.WasmExample.Benchmarks; 8 | 9 | /// 10 | /// Taken from: https://github.com/egil/Benchmark.Blazor/blob/main/Rendering/BenchmarkRenderer.cs 11 | /// 12 | #pragma warning disable BL0006 // Do not use RenderTree types 13 | internal class BenchmarkRenderer : Renderer 14 | { 15 | private readonly List rootComponentIds = new(); 16 | 17 | /// 18 | public override Dispatcher Dispatcher { get; } = Dispatcher.CreateDefault(); 19 | 20 | /// 21 | /// Any unhandled exceptions thrown by the Blazor Renderer after 22 | /// a call to or 23 | /// . 24 | /// 25 | /// 26 | /// This is reset after each call to or 27 | /// . 28 | /// 29 | public Exception?

Minimal Viable Example

9 |

10 | Using the Blazor.FileSystem library we can handle and store references to files. 11 | The file handles can be supplied from multiple other APIs (like File System Access or Web App Launch Handler). 12 |

13 |

14 | Alternatively you can read, write, create, and delete files and folders in a sandboxed environment called the Origin Private File System which is made available through the StorageManagerService (or StorageManagerServiceInProcess for WASM) in this library. 15 |

16 |

17 | Below we see a sample of a file called file.txt that has been opened from your Origin Private File System. The file is local to this domain in your browser, but is persisted accross page loads. 18 | Try writing in the textarea and then reload this page. 19 |

20 | 21 | @if (text is not null) 22 | { 23 | 24 | } 25 | 26 | @code { 27 | string? text = null; 28 | FileSystemFileHandle? fileHandle; 29 | 30 | protected override async Task OnInitializedAsync() 31 | { 32 | var directoryHandle = await StorageManagerService.GetOriginPrivateDirectoryAsync(); 33 | fileHandle = await directoryHandle.GetFileHandleAsync("file.txt", new() { Create = true }); 34 | var file = await fileHandle.GetFileAsync(); 35 | text = await file.TextAsync(); 36 | } 37 | 38 | async Task TextAreaChanged(ChangeEventArgs eventArgs) 39 | { 40 | if (fileHandle is not null && eventArgs.Value is string value) 41 | { 42 | var writable = await fileHandle.CreateWritableAsync(); 43 | await writable.WriteAsync(value); 44 | await writable.CloseAsync(); 45 | } 46 | } 47 | 48 | void Reload() 49 | { 50 | NavigationManager.NavigateTo("./", true); 51 | } 52 | } -------------------------------------------------------------------------------- /samples/KristofferStrube.Blazor.FileSystem.WasmExample/Pages/SearchMastodon.razor: -------------------------------------------------------------------------------- 1 | @page "/SearchMastodon" 2 | 3 | @using KristofferStrube.ActivityStreams; 4 | @using KristofferStrube.Blazor.FileSystem.WasmExample.Search; 5 | @using static System.Text.Json.JsonSerializer; 6 | @using System.Reactive.Linq; 7 | @using System.Reactive.Subjects; 8 | @using System.Diagnostics; 9 | 10 | @inject IStorageManagerService StorageManagerService 11 | @inject NavigationManager NavigationManager 12 | @inject HttpClient HttpClient 13 | 14 | File System - Search Mastodon 15 | 16 |

Search Mastodon

17 |

18 | This sample page uses Blazor.FileSystem together with KristofferStrube/ActivityStream to load a Mastodon user's posts, create search trees of their content, and store these search trees in the Origin Private File System so that they can be re-used on reloads or recurring searches. 19 |

20 | @if (OriginPrivateDirectoryHandle is null) 21 | { 22 |

23 | The File System API is only supported on few browsers, but most major vendors have committed to support it in the near future. So you might need to install alpha/beta release of your browser for this to work. This demo will run without using it in this case as your browser does not support it. 😢 24 |

25 | } 26 |

27 | You can make full text searches in my blog posts which I also expose through my private ActivityStreams bot (AcitivityPubBotDotNet) once they have been downloaded. You can also download the posts of another user by typing in their identifier. It downloads these posts and check in the file system if we have already created a suffix search tree for the post and uses that instead of creating a new one if available. The suffix tree can do a fuzzy search efficiently which allows small errors in the written search query. 28 |

It is a hyper-legible collection of 223 icons with a tiny footprint—ready to use with Bootstrap and Foundation. [View the collection](http://useiconic.com/open#icons) 5 | 6 | 7 | 8 | ## What's in Open Iconic? 9 | 10 | * 223 icons designed to be legible down to 8 pixels 11 | * Super-light SVG files - 61.8 for the entire set 12 | * SVG sprite—the modern replacement for icon fonts 13 | * Webfont (EOT, OTF, SVG, TTF, WOFF), PNG and WebP formats 14 | * Webfont stylesheets (including versions for Bootstrap and Foundation) in CSS, LESS, SCSS and Stylus formats 15 | * PNG and WebP raster images in 8px, 16px, 24px, 32px, 48px and 64px. 16 | 17 | 18 | ## Getting Started 19 | 20 | #### For code samples and everything else you need to get started with Open Iconic, check out our [Icons](http://useiconic.com/open#icons) and [Reference](http://useiconic.com/open#reference) sections. 21 | 22 | ### General Usage 23 | 24 | #### Using Open Iconic's SVGs 25 | 26 | We like SVGs and we think they're the way to display icons on the web. Since Open Iconic are just basic SVGs, we suggest you display them like you would any other image (don't forget the `alt` attribute). 27 | 28 | ``` 29 | icon name 30 | ``` 31 | 32 | #### Using Open Iconic's SVG Sprite 33 | 34 | Open Iconic also comes in a SVG sprite which allows you to display all the icons in the set with a single request. It's like an icon font, without being a hack. 35 | 36 | Adding an icon from an SVG sprite is a little different than what you're used to, but it's still a piece of cake. *Tip: To make your icons easily style able, we suggest adding a general class to the* `` *tag and a unique class name for each different icon in the* `` *tag.* 37 | 38 | ``` 39 | 40 | 41 | 42 | ``` 43 | 44 | Sizing icons only needs basic CSS. All the icons are in a square format, so just set the `` tag with equal width and height dimensions. 45 | 46 | ``` 47 | .icon { 48 | width: 16px; 49 | height: 16px; 50 | } 51 | ``` 52 | 53 | Coloring icons is even easier. All you need to do is set the `fill` rule on the `` tag. 54 | 55 | ``` 56 | .icon-account-login { 57 | fill: #f00; 58 | } 59 | ``` 60 | 61 | To learn more about SVG Sprites, read [Chris Coyier's guide](http://css-tricks.com/svg-sprites-use-better-icon-fonts/). 62 | 63 | #### Using Open Iconic's Icon Font... 64 | 65 | 66 | ##### …with Bootstrap 67 | 68 | You can find our Bootstrap stylesheets in `font/css/open-iconic-bootstrap.{css, less, scss, styl}` 69 | 70 | 71 | ``` 72 | 73 | ``` 74 | 75 | 76 | ``` 77 | 78 | ``` 79 | 80 | ##### …with Foundation 81 | 82 | You can find our Foundation stylesheets in `font/css/open-iconic-foundation.{css, less, scss, styl}` 83 | 84 | ``` 85 | 86 | ``` 87 | 88 | 89 | ``` 90 | 91 | ``` 92 | 93 | ##### …on its own 94 | 95 | You can find our default stylesheets in `font/css/open-iconic.{css, less, scss, styl}` 96 | 97 | ``` 98 | 99 | ``` 100 | 101 | ``` 102 | 103 | ``` 104 | 105 | 106 | ## License 107 | 108 | ### Icons 109 | 110 | All code
