# graphql-rules
A little utility allowing you to write rules for your graphql resolvers.
```javascript
import GraphqlRules from 'graphql-rules';
// All users rules
const userRules = new GraphqlRules();
userRules.addRule({
// Name of the rule
name: 'is-logged',
// Function called when the rule is required
resolver: (obj, args, context) => {
// your logic here
if (!context.userId) {
throw new Error('Forbidden');
}
},
});
userRules.addRule({
// Name of the rule
name: 'is-admin',
// Function called when the rule is required
resolver: (obj, args, context) => {
// your logic here
if (!context.user.isAdmin()) {
throw new Error('Forbidden');
}
},
});
// Your resolver object
const resolverMap = {
Query: {
// Your graphql query resolver
users: userRules.check({
// Define your required rules
rules: ['is-admin', 'other-rules', 'is-logged'],
// Define your resolver
// The rules need to pass before the resolver is executed
resolver: (obj, args, context) => {
return context.Users.find();
},
}),
},
Mutation: {
addSomeDbObject: userRules.check({
// Check the user is logged
rules: 'is-logged',
resolver: (obj, args, context) => {
return MyModel.insert(context.obj);
},
}),
},
};
```
