souljs
A nodejs web framework, 对koa简单包装,装饰风格,内置开发常用中间件,使用typescript编写
快速开始
git clone https://github.com/test/souljs-starter.git
npm install && npm run start
Node.js >= 8.0.0 required.
创建应用实例
import { createApplication } from 'souljs';
import * as router from './router';
async function main() {
const app = await createApplication(__dirname, Object.keys(router).map(k => router[k]));
app.listen(8080);
}
main();
路由处理并返回数据
@Controller('/user')
export default class User {
@Post('/chname')
changeName() {
return ‘hello world’;
}
}
通过@Render返回视图
@Controller('/user')
@Use(Auth())
export default class User {
@Get()
@Render('user')
index() {
return { content: 'hi' };
}
}
请求参数验证
@Controller('/user')
@Role(SYS_ROLE.admin)
export default class User {
@Post('/chname')
@QuerySchame({
username: joi.string().required(),
password: joi.string().required(),
})
changeName(@Body() body: any, @Query() query: any) {
return ResultUtils.ok(body);
}
}
接口描述
接口文档默认访问地址: /swagger-ui/index.html
@Controller('/user')
@Description('用户信息')
export default class User {
@Post('/hi')
@Description('test')
test() {}
}
计划任务 @CronJob
使用修饰器@CronJob执行计划任务
@Controller()
@Description('用户信息')
export default class User {
@CronJob('* * * * * *', { onlyRunMaster: false }) // 多进程下是否只在master进程执行 default: true
cron() {
console.log('计划任务执行了!');
}
}
API
createApplication(root, controllers, options): Application
参数
- { string } root - 项目路径
- { string | controller[] } controllers - 控制器的目录位置,使用globs匹配,或者是控制器类的数组
- { ApplicationOptions } options - 参考如下ApplicationOptions, 值false不启用功能
interface ApplicationOptions { staticAssets?: { root: string; prefix?: string } | boolean; // default: disable https://github.com/koajs/static swagger?: { url: string; prefix?: string } | boolean; // swagger-ui bodyparser?: Bodyparser.Options | boolean; // https://github.com/koajs/bodyparser cors?: object | boolean; // https://github.com/koajs/cors hbs?: { viewPath?: string } | boolean; // default: disable https://github.com/koajs/koa-hbs helmet?: object | boolean; // https://github.com/venables/koa-helmet }
返回值:Application
Application
实例方法
use(mid: Koa.Middleware)
listen(port: number)
getKoaInstance(): Koa
getHttpServer(): http.Server
http请求装饰器
内部使用koa-router中间件,提供对应的方法的装饰器
@Controller(string|void)
@POST(string|void)
@Get(string|void)
@Render(view: string) 模板渲染
使用Joi验证请求参数
BodySchame(schame: joi.AnySchema)
QuerySchame(schame: joi.AnySchema)
控制器处理方法参数注入
@Post('/test')
test(@Body() Body: any, @Query() query: any) {}
自定义装饰器
import { Use, Description } from 'souljs';
export default function Role(...roles: string[]) {
const role = Use(async (ctx: Koa.Context, next: () => void) => {
const sql = `
SELECT R.code FROM role R
LEFT JOIN user_roles UR ON UR.role_id = R.id
WHERE UR.user_id = ?
`;
const userRoles = await db.query(sql, [signData.id]);
if (roles.some(r => userRoles.find(ur => ur.code === r))) {
await next();
} else {
throw new Error('no authorization!');
}
});
const description = Description(`【${roles.join()}】`);
return (target: any, propertyKey?: string) => {
role(target, propertyKey);
description(target, propertyKey);
};
}
// 使用装饰器
@Controller('/system/role')
@Role(SYS_ROLE.admin)
export class RoleController {
@Get('/list')
@Description('角色列表')
async list() { }
}
提供如下修饰器
@Ctx() - ctx
@Request() - ctx.request
@Response() - ctx.Response
@Query(string|void) - ctx.request.query[string] | ctx.request.query
@Body(string|void) - ctx.request.body[string] | ctx.request.body
@ApplicationInstance() - 当前应用实例
@KoaInstance() - 当前koa实例
