# Knit
Knit is a lightweight framework for Roblox that simplifies communication between core parts of your game and seamlessly bridges the gap between the server and the client.
Read the [documentation](https://sleitnick.github.io/Knit/) for more info.
## Install
Installing Knit is very simple. Just drop the module into ReplicatedStorage. Knit can also be used within a Rojo project.
**Roblox Studio workflow:**
1. Get [Knit](https://www.roblox.com/library/5530714855/Knit) from the Roblox library.
1. Place Knit directly within ReplicatedStorage.
**Wally & Rojo workflow:**
1. Add Knit as a Wally dependency (e.g. `Knit = "sleitnick/knit@^1"`)
1. Use Rojo to point the Wally packages to ReplicatedStorage.
## Basic Usage
The core usage of Knit is the same from the server and the client. The general pattern is to create a single script on the server and a single script on the client. These scripts will load Knit, create services/controllers, and then start Knit.
The most basic usage would look as such:
```lua
local Knit = require(game:GetService("ReplicatedStorage").Packages.Knit)
Knit.Start():catch(warn)
-- Knit.Start() returns a Promise, so we are catching any errors and feeding it to the built-in 'warn' function
-- You could also chain 'await()' to the end to yield until the whole sequence is completed:
-- Knit.Start():catch(warn):await()
```
That would be the necessary code on both the server and the client. However, nothing interesting is going to happen. Let's dive into some more examples.
### A Simple Service
A service is simply a structure that _serves_ some specific purpose. For instance, a game might have a MoneyService, which manages in-game currency for players. Let's look at a simple example:
```lua
local Knit = require(game:GetService("ReplicatedStorage").Packages.Knit)
-- Create the service:
local MoneyService = Knit.CreateService {
Name = "MoneyService",
}
-- Add some methods to the service:
function MoneyService:GetMoney(player)
-- Do some sort of data fetch
local money = someDataStore:GetAsync("money")
return money
end
function MoneyService:GiveMoney(player, amount)
-- Do some sort of data fetch
local money = self:GetMoney(player)
money += amount
someDataStore:SetAsync("money", money)
end
Knit.Start():catch(warn)
```
Now we have a little MoneyService that can get and give money to a player. However, only the server can use this at the moment. What if we want clients to fetch how much money they have? To do this, we have to create some client-side code to consume our service. We _could_ create a controller, but it's not necessary for this example.
First, we need to expose a method to the client. We can do this by writing methods on the service's Client table:
```lua
-- Money service on the server
...
function MoneyService.Client:GetMoney(player)
-- We already wrote this method, so we can just call the other one.
-- 'self.Server' will reference back to the root MoneyService.
return self.Server:GetMoney(player)
end
...
```
We can write client-side code to fetch money from the service:
```lua
-- Client-side code
local Knit = require(game:GetService("ReplicatedStorage").Packages.Knit)
Knit.Start():catch(warn):await()
local MoneyService = Knit.GetService("MoneyService")
MoneyService:GetMoney():andThen(function(money)
print(money)
end)
```
Under the hood, Knit is creating a RemoteFunction bound to the service's GetMoney method. Knit keeps RemoteFunctions and RemoteEvents out of the way so that developers can focus on writing code and not building networking infrastructure.
