@evio/hookable
以最简单方式实现 Class hookable 模型。它可以将class作为一个工作流,通过标准的I/O模型产生数据。
Usage
import { Hook } from '@pjblog/hookable';
class ABC extends Hook<number, number> {
public res = 0;
@Hook.Entry
@Hook.Node
public async a() {
this.res += this.req * 2;
const j = await this.b(4);
this.res += j;
}
@Hook.Node
async b(a: number) {
this.res += this.req * 3 + a;
return 1;
}
}
// invoke
const obj = new ABC(99);
obj.$hook('b').before('c', o => {
console.log('c')
o.res += 1;
})
obj.$hook('b').insertAfter('c', 'd', o => {
console.log('d')
o.res += 1;
})
obj.$hook('b').insertBefore('c', 'e', o => {
console.log('e')
o.res -= 1;
})
obj.$execute().then(console.log).catch(console.error);
// output:
// e
// c
// d
// 501
Use Container
使用全局注册
import { Hook } from '@pjblog/hookable';
@Hook.Container
class ABC extends Hook<number, number> {
public res = 0;
@Hook.Entry
@Hook.Node
public async a() {
this.res += this.req * 2;
const j = await this.b(4);
this.res += j;
}
@Hook.Node
async b(a: number) {
this.res += this.req * 3 + a;
return 1;
}
}
const unbind = Hook.use(ABC, abc => {
abc.$hook('a').after('k', obj => {
console.log('k')
obj.res += 1;
})
})
// invoke
const obj = new ABC(99);
obj.$hook('b').before('c', o => {
console.log('c')
o.res += 1;
})
obj.$hook('b').insertAfter('c', 'd', o => {
console.log('d')
o.res += 1;
})
obj.$hook('b').insertBefore('c', 'e', o => {
console.log('e')
o.res -= 1;
})
obj.$execute().then(console.log).catch(console.error);
setTimeout(() => {
unbind();
console.log('-----------')
const x = new ABC(99);
x.$execute().then(console.log).catch(console.error);
}, 2000);
// output:
// e
// c
// d
// k
// 502
// -----------
// 500
