# Soenneker.Blazor.Utils.Cookies

Blazor library for reading, writing, removing, and listing browser cookies. Exposes a low-level `ICookiesInterop` for direct browser interop and a higher-level `ICookiesUtil` for app-facing usage.

---

## Install

```bash

dotnet add package Soenneker.Blazor.Utils.Cookies

```

---

## Setup

Register cookie services in `Program.cs`:

```csharp

builder.Services.AddCookiesUtilAsScoped();

```

Inject the higher-level utility in components/services:

```csharp

@inject ICookiesUtil Cookies

```

---

## Usage

### Get a cookie

```csharp

string? theme = await Cookies.Get("theme");

```

### Try get a cookie

```csharp

CookieGetResult result = await Cookies.TryGet("theme");

if (result.Found)

{

    Console.WriteLine(result.Value);

}

```

### Set a cookie

```csharp

await Cookies.Set("theme", "dark", new CookieOptions

{

    Path = "/",

    MaxAge = TimeSpan.FromDays(30),

    Secure = true,

    SameSite = CookieSameSite.Lax

});

```

### Remove a cookie

```csharp

await Cookies.Remove("theme");

```

### Read all cookies

```csharp

IReadOnlyDictionary cookies = await Cookies.GetAll();

foreach ((string key, string value) in cookies)

{

    Console.WriteLine($"{key}={value}");

}

```
