### Standard Example
```javascript
const launcher = require('minecraft-launcher-core');
const { Client, Authenticator } = require('minecraft-launcher-core');
launcher.authenticator.getAuth("email", "password").then(auth => {
// Save the auth to a file so it can be used later on!
launcher.core({
authorization: auth,
let opts = {
authorization: async () => { return await Authenticator.getAuth(username, password) },
clientPackage: null,
forge: null,
root: "C:/Users/user/AppData/Roaming/.mc",

memory: {
max: "3000",
min: "1000"
}
});
});
memory: {

}
const launcher = new Client(opts);
launcher.launch();
launcher.on('debug', (e) => console.log(e));
launcher.on('data', (e) => console.log(e));
launcher.on('error', (e) => console.log(e));

if you don't provide downloads url downloads like Forge and Fabric. Still need to provide the version jar.

#### Client Package Function
Client Packages allow the client to run offline on setup. This function should be used outside the actual launcher.
this function is in the `handler` component.

### Other Examples
##### Using Validate and Refresh
```javascript
let auth = require("pathToUserAuthJson.json");
const validateCheck = await launcher.authenticator.validate(auth.access_token);
if(!validateCheck) {
auth = await launcher.authenticator.refreshAuth(auth.access_token, auth.client_token, auth.selected_profile);
}
launcher.core({
authorization: auth,
clientPackage: null,
root: "directory",
os: "windows",
version: {
number: "1.13.2",
type: "MCC-Launcher"
},
memory: {
max: "500",
min: "100"
}
});
```
##### Using With Forge
```js
launcher.authenticator.getAuth("email", "password").then(auth => {
launcher.core({
authorization: auth,
clientPackage: null,
root: "C:/Users/user/AppData/Roaming/.mc",
forge: "C:/Users/user/Desktop/forge.jar",
os: "windows",
version: {
number: "1.12.2", // needs to be the same as the Forge version
type: "MCC-Launcher"
},
memory: {
max: "500",
min: "100"
}
});
});
```
