koahub.js 0.09 released, new hook mechanism

koahub.js 0.09 released, new hook mechanism
koahubjs released 0.09 with new hook mechanism

Add hook mechanism, controller hook and function hook
Fix the auto-loading bug and realize that in addition to automatically loading the exported default, other methods can also be automatically loaded

Remember the koahubjs hook development process

After using koahubjs to develop a project, it is always necessary to add some additional plug-in functions. In this case, changing the project code is too risky, so the hook mechanism is indispensable. koahubjs loads the hook into memory because the koahubjs framework does not have a built-in database, and loading into memory is more flexible.

Hook 1

Controller Hooks
When executing an http request, you want to call the method of another controller

Hook 2

Method hook
When executing an http request, you want to call a public function

Go directly to the code//Create hook.class.js
//hooks definition
// {
// addOrder: [
//         '/admin/index/index'
// ]
// }

export default class {
​​constructor() {
This.hooks = {};
}

Get() {
                               return this.hooks;
}

Add(name, action) {
                    let add = true;
for (let key in this.hooks) {
                                                                                                                                                                                                                                                if (name == key) {
This.hooks[key].push(action);
                   add = false;
            }
         }
           if (add) {
This.hooks[name] = [action];
         }

          return this.get();
}

​ run(name) {
for (let key in this.hooks) {
                                                                                                                                                                                                                                               if (name == key) {
for (let path of this.hooks[key]) {
If (/w+(.*)$/.test(path)) {
This.runFunction(path);
                                                                                                                                                                                                                                                               – This.runController(path);
                    }
                 }
            }
         }
}

​ runController(path) {
​​​​​let action = path.slice(path.lastIndexOf('/'));
path = path.slice(0, path.lastIndexOf('/'));

Let include = false;
​​​​​for (let _key in koahub.controllers) {
                if (_key == path) {
                include = true;
                break;
            }
        }
 
        if (include) {
            let ctrl = koahub.controllers[path];
            let pros = Object.getOwnPropertyNames(ctrl.prototype).filter(function(value) {
                if (value == 'constructor') {
                    return false;
                }
                return true;
            });
 
            let callFlag = true;
            for (let k in pros) {
                if ('/' + pros[k] == action) {
                    Object.getPrototypeOf(new ctrl())[pros[k]].call(this);
                    callFlag = false;
                }
            }
 
            if (callFlag) {
                console.error('Hook Not Found Method');
            }
        } else {
            console.error('Hook Not Found Controller');
        }

}钩子需要提前挂载到相应的节点上//开始挂载
//controller钩子
koahub.hook.add('hook1', '/admin/public/sendEmail');
//function钩子
koahub.hook.add('hook2', 'tools.add(1,2)');
 
//调用钩子
koahub.hook.run('hook1');
koahub.hook.run('hook2');util方法//util下的*.util.js会自动挂载到koahub.utils上
//util/tools.util.js
export function add(a, b) {
    console.log(a + b);
    return a + b;
}
 
export function dis(a, b) {
    console.log(a - b);
    return a - b;
