### 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,
clientPackage: null,
forge: null,
root: "C:/Users/user/AppData/Roaming/.mc",
os: "windows",
version: {
number: "1.13.2",
type: "release"
},
memory: {
max: "3000",
min: "1000"
}
});
});
let opts = {
authorization: async () => { return await Authenticator.getAuth(username, password) },

launcher.on('debug', (e) => console.log(e));
launcher.on('data', (e) => console.log(e));
launcher.on('error', (e) => console.log(e));

##### Note
If you are loading up a client outside of vanilla Minecraft or Forge (Optifine and for an example), you'll need to download the needed files yourself
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"
}
});
});
```
#### What should it look like running from console?
