Basic Utility

These basic utility APIs provide core functionality for networking and checking compatibility within the Mini Game environment.

.request

Initiate an HTTPS network request from the mini‑game runtime. Use it to call your own backend or lightweight public endpoints.

ReqeustTask

RequestTask.abort

Abort an in‑flight request task, like when the user navigates away.

const task = TTMinis.game.request({...});
// later
task.abort();

.canIUse(schema)

An API compatibility check that determines whether a specific TikTok JavaScript API, its method, return value, or parameter is available in the user's current TikTok version. This prevents runtime errors on older clients.

Always gate new or version‑specific features before use (features available from v41.0.0).

API

The API parameter specifies the specific API name to be checked, such as login, setLoadingProgress, getMenuButtonBoundingClientRect, and more.

// Check if the login API is available
TTMinis.game.canIUse('login');

// Check if the getMenuButtonBoundingClientRect API is available
TTMinis.game.canIUse('getMenuButtonBoundingClientRect');

Method

The method parameter specifies the calling method of the API, and valid values include the following:

The following are example usages of each calling method:

• success: Callback function for successful execution check and its parameters:

// Original API call method
TTMinis.login({
  success: (res) => {
    console.log(res.code); // Check if res.code is available
    console.log(res.token); // Check if res.token is available
  }
});

// Using canIUse to check
TTMinis.game.canIUse('login.success'); // Check if the success callback is available
TTMinis.game.canIUse('login.success.code'); // Check if the code parameter in the success callback is available
TTMinis.game.canIUse('login.success.token'); // Check if the token parameter in the success callback is available

• return: Check the return value of the synchronization method:

// Original API call method
const buttonInfo = TTMinis.getMenuButtonBoundingClientRect();
console.log(buttonInfo.width);
console.log(buttonInfo.height);

// Using canIUse to check
TTMinis.game.canIUse('getMenuButtonBoundingClientRect.return'); // Check if the return value is available
TTMinis.game.canIUse('getMenuButtonBoundingClientRect.return.width'); // Check if the width property in the return value is available
TTMinis.game.canIUse('getMenuButtonBoundingClientRect.return.height'); // Check if the height property in the return value is available

• callback: Check the callback parameters of asynchronous methods:

// Original API call method
TTMinis.onShow((params) => {
  console.log(params.query);
});

// Using canIUse to check
TTMinis.game.canIUse('onShow.callback'); // Check if the callback is available
TTMinis.game.canIUse('onShow.callback.query'); // Check if the query parameter in the callback is available

• object: Check the parameters of the request parameter object

// Original API call method
TTMinis.login({
  clientKey: 'clientKey',
  scope: 'scope'
});

// Using canIUse to check
TTMinis.game.canIUse('login.object'); // Check if the object parameter is available
TTMinis.game.canIUse('login.object.clientKey'); // Check if the clientKey parameter in the object is available
TTMinis.game.canIUse('login.object.scope'); // Check if the scope parameter in the object is available

Param

The param parameter specifies the specific parameter or return value to be checked, and has different usages depending on the method:

Option

The option parameter is used to check whether a specific enumeration value is available. In most cases, this parameter does not need to be used; it is only necessary to use this parameter to check whether a specific enumeration value is available when a parameter or return value is of a definite enumeration type.

// Check if the 'anchor' enumeration value for the 'launch_from' parameter in the onShow callback is available
TTMinis.game.canIUse('onShow.callback.launch_from.anchor'); // true

// Check if the 'profile' enumeration value for the 'launch_from' parameter in the onShow callback is available
TTMinis.game.canIUse('onShow.callback.launch_from.profile'); // false

env

Provides read-only access to mini game runtime environment variables.
