Full Update #

Downloads a new bundle from a server that developer assigns, and replaces the original one (the bundle built in the App).

Build Update #

You may use function or CLI to build update.

import {build} from '@herina-rn/core';
import herinaConfig from './herina.config';

const start = async (config: any) => {
  await build(config);
};

start(herinaConfig);

npx herina build-chunks herina.config.js

Build versions.json #

import {buildVersionsJson, HerinaConfig} from '@herina-rn/core';
import herinaConfig from './herina.config';

const start = async (config: HerinaConfig) => {
  await buildVersionsJson(config);
};

start(herinaConfig);

npx herina build-versions-json herina.config.js

Upload Files #

After the update is built, upload the output files to the server matching baseUrl in the configuration.

The files to upload include:

• main.chunk.js
• *.dynamic.chunk.js
• versions.json

Download Bundle #

Before downloading the update, you are supposed to check whether an update is available by calling checkForUpdate.

checkForUpdate(): Promise<boolean>

After checking the version, call requestUpdate to download the latest bundle.

requestUpdate(): Promise<boolean>;

Apply Update #

Finally, call applyUpdate to replace the original bundle with the downloaded one.

The first argument indicates whether to reload the App after the update is applied.

applyUpdate(immediate: boolean): Promise<boolean>;

If you intend to apply the update later, but you're not sure whether you've called requestUpdate or not. Call isUpdateAvailable to get your answer.

isUpdateAvailable(): Promise<boolean>;

Restore to the Original #

Somehow, you shipped some code with business or logical errors that crash your App. In this case, call setUseOriginalBundle(true) and reloadApp() to restore your bundle to the original one.

setUseOriginalBundle(original: boolean): Promise<boolean>;

reloadApp(): Promise<boolean>;
