Demo Playground

Vona provides a Demo Playground, which allows us to test the code and verify the ideas very conveniently and quickly

Steps

1. Create a new demo file

We need to create a new source code file: src/backend/demo/index.ts. Currently, we do not need to create this file manually, but execute the following command to automatically create the file:

$ vona demo

2. Write test code

In the file demo/index.ts, we write the test code:

export async function main(app: VonaApplication, _argv: IArgv) {
  console.log('server listen: ', app.config.server.listen);
}

3. Execute demo file

$ vona demo

Example

1. Simulate the context object of the request

export async function main(app: VonaApplication, _argv: IArgv) {
  await app.bean.executor.mockCtx(async () => {
    // do something in ctx
  });
}

2. Access the API

For example, we access the home API:

export async function main(app: VonaApplication, _argv: IArgv) {
  await app.bean.executor.mockCtx(async () => {
    const homeBody = await app.bean.executor.performAction('get', '//');
    console.log(homeBody); // Hello Vona!
  });
}

We can also simulate Chinese ctx and then access the home API:

export async function main(app: VonaApplication, _argv: IArgv) {
  await app.bean.executor.mockCtx(async () => {
    const homeBody = await app.bean.executor.performAction('get', '//');
    console.log(homeBody);
  }, { locale: 'zh-cn' }); // 您好, Vona!
}

3. Simulate signin and signout

export async function main(app: VonaApplication, _argv: IArgv) {
  await app.bean.executor.mockCtx(async () => {
    // signin as user: admin
    await app.bean.passport.signinMock();
    // do something
    // signout
    await app.bean.passport.signout();
  });
}
