 1 | # How to contribute
 2 | Contributing includes many different actions. 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.Relewise/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.

 8 | # Introduction
 9 | A Blazor wrapper for the [Service Workers](https://www.w3.org/TR/service-workers/) API.
10 | 
11 | The API makes it possible to interact with and register a Service Worker that can control the fetching of resources for the website before any other contexts exist. This enables developers to make Progressive Web Apps (PWA). This project implements a wrapper around the API for Blazor so that we can easily and safely interact with and create Service Workers.
12 | 
13 | **This wrapper is still being developed, so support is very limited.**
14 | 
15 | # Demo
16 | The sample project can be demoed at https://kristofferstrube.github.io/Blazor.ServiceWorker/
17 | 
18 | On each page you can find the corresponding code for the example in the top right corner.
19 | 
20 | On the [API Coverage Status](https://kristofferstrube.github.io/Blazor.ServiceWorker/Status) page you can get an overview over what parts of the API we support currently.
21 | 
22 | # Getting Started
23 | A limitation of statically served Service Workers is that they only have access to the scope that the actual file belong in.
24 | So we need to place the Service Worker interop bootstrapper in the root of our project. You can find that [here](https://github.com/KristofferStrube/Blazor.ServiceWorker/blob/main/samples/KristofferStrube.Blazor.ServiceWorker.WasmExample/wwwroot/service-worker.js), but the content is pretty simple:
25 | ```js
26 | importScripts("_content/KristofferStrube.Blazor.ServiceWorker/KristofferStrube.Blazor.ServiceWorker.Script.js")
27 | ```
28 | 
29 | Then once we have copied the script to the root of `wwwroot` in our project we can register a service worker like so:
30 | 
31 | ```csharp
32 | var builder = WebAssemblyHostBuilder.CreateDefault(args);
33 | 
34 | // other services added and root components configured
35 | 
36 | builder.Services.AddNavigatorService();
37 | 
38 | var app = builder.Build();
39 | 
40 | var navigator = app.Services.GetRequiredService<INavigatorService>();
41 | var serviceWorker = await navigator.GetServiceWorkerAsync();
42 | var rootPath = "";
43 | 
44 | await serviceWorker.RegisterAsync("./service-worker.js", rootPath, async (scope) => {
45 |     scope.OnActivate = async () =>
46 |     {
47 |         Console.WriteLine("We will do something when activating!");
48 |     };
49 | });
50 | ```
51 |

  2 | ===========

  4 | ### Open Iconic is the open source sibling of [Iconic](https://github.com/iconic/open-iconic). It is a hyper-legible collection of 223 icons with a tiny footprint&mdash;ready to use with Bootstrap and Foundation. [View the collection](https://github.com/iconic/open-iconic)
  5 |

  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&mdash;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](https://github.com/iconic/open-iconic) and [Reference](https://github.com/iconic/open-iconic) 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 | <img src="/open-iconic/svg/icon-name.svg" alt="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* `<svg>` *tag and a unique class name for each different icon in the* `<use>` *tag.*
 37 | 
 38 | ```
 39 | <svg class="icon">
 40 |   <use xlink:href="open-iconic.svg#account-login" class="icon-account-login"></use>
 41 | </svg>
 42 | ```
 43 | 
 44 | Sizing icons only needs basic CSS. All the icons are in a square format, so just set the `<svg>` 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 `<use>` tag.
 54 | 
 55 | ```
 56 | .icon-account-login {
 57 |   fill: #f00;
 58 | }
 59 | ```
 60 |

 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 | <link href="/open-iconic/font/css/open-iconic-bootstrap.css" rel="stylesheet">
 73 | ```
 74 | 
 75 | 
 76 | ```
 77 | <span class="oi oi-icon-name" title="icon name" aria-hidden="true"></span>
 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 | <link href="/open-iconic/font/css/open-iconic-foundation.css" rel="stylesheet">
 86 | ```
 87 | 
 88 | 
 89 | ```
 90 | <span class="fi-icon-name" title="icon name" aria-hidden="true"></span>
 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 | <link href="/open-iconic/font/css/open-iconic.css" rel="stylesheet">
 99 | ```
100 | 
101 | ```
102 | <span class="oi" data-glyph="icon-name" title="icon name" aria-hidden="true"></span>
