创建命令

thinkjs new xxx typescript

##js代码，controller/index.ts

import Base from './base.js';
export default class extends Base {
    indexAction() {
        let a: number = 'a';
        return this.display();
    }
}

编译

[2018-02-01T10:50:19.740] [17192] [INFO] - transpile file controller\index.ts success
[2018-02-01T10:50:21.201] [17192] [INFO] - transpile file controller\index.ts success

tsc编译

tsc src\controller\index.ts
src/controller/index.ts(4,13): error TS2322: Type '"a"' is not assignable to type 'number'.
src/controller/index.ts(5,21): error TS2339: Property 'display' does not exist on type 'default'.

Start with the TypeScript project created by thinkjs new xxx typescript and the transpilation path exercised on controller/index.ts. Compare its compiler configuration and diagnostics with tsc src\\controller\\index.ts, then verify that an invalid assignment produces a compile-time error instead of a success message.
