Why Hook is called in all update services methods - node.js

Question

I'm create a hook file with the following information, which is Hooks.js
Hooks.js is working to authenticate an actions with JWT when need it, I dont need it in all servies calls.
As my understanding the syntax to call a hook was app/use route/hooks and those hooks were only applied to and specific route and not globally.
module.exports = {
errorHandler: (context) => {
if (context.error) {
context.error.stack = null;
return context;
}
},
isValidToken: (context) => {
const token = context.params.headers.authorization;
const payload = Auth.validateToken(token);
console.log(payload);
if(payload !== "Invalid" && payload !== "No Token Provided"){
context.data = payload._id;
}
else {
throw new errors.NotAuthenticated('Authentication Error Token');
}
},
isValidDomain: (context) => {
if (
config.DOMAINS_WHITE_LIST.includes(
context.params.headers.origin || context.params.headers.host
)
) {
return context;
}
throw new errors.NotAuthenticated("Not Authenticated Domain");
},
normalizedId: (context) => {
context.id = context.id || context.params.route.id;
},
normalizedCode: (context) => {
context.id = context.params.route.code;
},
};
Then I create a file for services and routes, like the following:
const Hooks = require("../../Hooks/Hooks");
const userServices = require("./user.services");
module.exports = (app) => {
app
.use("/users", {
find: userServices.find,
create: userServices.createUser,
})
.hooks({
before: {
find: [Hooks.isValidDomain],
create: [Hooks.isValidDomain],
},
});
app
.use("/users/:code/validate", {
update: userServices.validateCode,
})
.hooks({
before: {
update: [Hooks.isValidDomain, Hooks.normalizedCode],
},
});
app
.use("/users/personal", {
update: userServices.personalInfo,
})
.hooks({
before: {
update: [Hooks.isValidDomain, Hooks.isValidToken],
},
});
};
Why Hooks.isValidToken applies to all my update methods? Even if I'm not calling it?
Please help.

app.hooks registers an application level hook which runs for all services. If you only want it for a specific service and method it needs to be app.service('users').hooks().
