Authorization

With SugoiJS Authorization check is that simple.
Overview
/**
 *  requiredRole: TStringOrNumber|TStringOrNumber[] - The required role(s)
 *  permissions: TStringOrNumber|TStringOrNumber[]  - The required premission(s)
 *  failedCode: number                              - The response code in case the policy will fail
 **/
Authorized(requiredRole: TStringOrNumber|TStringOrNumber[] = null, permissions: TStringOrNumber|TStringOrNumber[] = null, failedCode: number = 401)
The Authorized decorator use for validate if the user is authorized and in the right role & have the right permissions(optional).
In case null will pass the value won't be checked.
Initialize
The Authorized policy will use the AuthProvider which pass while the server init: init(boostrapModule: any, rootPath?: string, moduleMetaKey?: string, authProvider?: AuthProvider)
The AuthProvider will init for each request, the AuthProvider holding the request headers & cookies.
Example
authorization.class.ts
app.ts
dashboard.controller.ts
export class Authorization extends AuthProvider<User> {
​
​
    /**
     * Verify if user is authorized
     *
     * Implemented dummy check for x-sug-demo header to be equal to "Wyn1RRR9PQJPaqYM"
     *
     * @returns {Promise<boolean>}
     */
    isAuthenticated(): Promise<boolean> {
        return Promise.resolve(this.headers["x-sug-demo"] === "Wyn1RRR9PQJPaqYM");
    }

    getUser(req?: e.Request, res?: e.Response, next?: e.NextFunction): Promise<any> {
        return this.details 
            ?   Promise.resolve(this.details)
            : UserService.getUser(UserService.getIdFromCookie(this.cookie))
                          .then((user:User)=>{
                            this.details = user;
                            return user;
                          })
    }

    isInRole(...roles: Array<string | number>): Promise<boolean> {
        return this.getUser().then(user=>roles.includes(user.role));
