Mdorinth OAuth Provider

[TheCukitoDev]

Hello, I'm doing a proyect related to minecraft so i need to use the modrinth api to get data from mods and releases,... I need to do a custom provider but i don't know well how to do it. Does it already exits an Modrinth OAuth or how could I do one?? I readed the docs but I am not very confort with authjs (and also with any auth system) yet so I need help. Thank you 😄

UPDATE. I already had seen some videos but the problem is the oauth provider (Modrinth). I need a way to get the URLSearchParams to use them into a function to get the token. This is the code i already have: `import type { OAuthConfig, OAuthUserConfig } from "@auth/core/providers"
import type { AxiosResponse } from "axios"
import axios from 'axios'

// Tipos actualizados para el perfil de usuario de Modrinth
interface ModrinthProfile {
username: string
name: string
email: string
bio: string
payout_data: {
balance: number
payout_wallet: string
payout_wallet_type: string
payout_address: string
}
id: string
avatar_url: string
created: string
role: string
badges: number
auth_providers: string[]
email_verified: boolean
has_password: boolean
has_totp: boolean
github_id: number | null
}

// Tipos para la respuesta del token de Modrinth
interface ModrinthTokenResponse {
access_token: string
token_type: string
expires_in: number
}

// Tipos para los tokens
interface ModrinthTokens {
access_token: string
token_type: string
expires_in: number
}

// Tipos para los parámetros de la función de solicitud de token
interface TokenRequestParams {
params: {
code: string
}
provider: {
callbackUrl: string
}
}

// Tipos para los parámetros de la función de solicitud de información del usuario
interface UserInfoRequestParams {
tokens: ModrinthTokens
}

// Nueva interfaz para los estilos del proveedor
interface ProviderStyle {
logo: string
logoDark?: string
bg: string
text: string
bgDark?: string
textDark?: string
}

function handleToken(code:string) {
// This is where I have to use the URLSearchParams to send the code to the API to retrieve the token
}

function handleUserInfo() {
// And here I have to use the token to retrieve the user information
};

export default function ModrinthProvider(
config: OAuthUserConfig
): OAuthConfig {
return {
id: "modrinth",
name: "Modrinth",
type: "oauth",
authorization: https://modrinth.com/auth/authorize?client_id=${process.env.MODRINTH_CLIENT_ID}&redirect_uri=http://localhost:3000/api/auth/callback/modrinth&scope=USER_READ+USER_READ_EMAIL,

token: handleToken(''),
userinfo: handleUserInfo(),
style: {
  logo: "/modrinth-logo.png",
  bg: "#30B27B",
  text: "#fff",
} as ProviderStyle,

}
}`
