Roles

Introduction

Roles are an effective way to restrict user depending on what he can or cannot do.

Structure of a role

{
    "ROLE_MOD_INVOICE_LINE_ADD": "ROLE_MOD_INVOICE_LINE_ADD"
}

Example of usage in app

Because they aren't often updated, it's better to store them in localstorage

In your hooks (Eg. GetRoles)

Create a function to get the list of user's roles
- Get the list of roles from localstorage
- If there is no roles in localstorage, get the list roles of the specific user from API Link : open-api/v3/users/logged_user_roles/get

Example :

    const GetRoles = async () => {
        let roles = {};
        if (typeof window !== "undefined" && localStorage.roles) {
            roles = JSON.parse(localStorage.roles);
        }

        if (!roles || roles.length === 0) {
            roles = await fetchRoles();
            localStorage.roles = JSON.stringify(roles);
        }

        return roles;
    }

Create a RolesEnum (in your utils directory)

Add all the roles that are needed in the app in that enum Example :

export enum ROLES_ENUM {
    ROLE_MOD_INVOICE_DISTRIBUTIONTYPE_DROPDOWN = "ROLE_MOD_INVOICE_DISTRIBUTIONTYPE_DROPDOWN",
    ROLE_MOD_INVOICE_TYPE_DROPDOWN = "ROLE_MOD_INVOICE_TYPE_DROPDOWN",
    ROLE_MOD_INVOICE_STATUS_DROPDOWN = "ROLE_MOD_INVOICE_STATUS_DROPDOWN",
    ROLE_MOD_INVOICE_UPDATE_PRICES = "ROLE_MOD_INVOICE_UPDATE_PRICES",
    ROLE_MOD_INVOICE_LINE_DROPDOWN = "ROLE_MOD_INVOICE_LINE_DROPDOWN",
    ROLE_MOD_INVOICE_LINE_ADD = "ROLE_MOD_INVOICE_LINE_ADD",
    ROLE_MOD_INVOICE_LINE_LISTING = "ROLE_MOD_INVOICE_LINE_LISTING",
    ROLE_MOD_INVOICE_PRINT = "ROLE_MOD_INVOICE_PRINT"
}

In your component

Get the Roles list (from localstorage or API) Example :

    const rolesArray = await GetRoles();

Get the roles enum
Then use the roles enum to verify if the user has the role or not to access ta data/field Example :

{arrayRoles && 
  arrayRoles.ROLE_MOD_INVOICE_LINE_ADD === ROLES_ENUM.ROLE_MOD_INVOICE_LINE_ADD && (
    <div>Invoice line add</div>
)
}
