Incremental Update #

Incremental update requires your project to be a Git repository to find out the differences from the last commit. Heina builds a chunk including all modified modules for updating.

Build Update #

You may use function or CLI to build update.

import { buildIncremental } from "@herina-rn/core";
import config from "./herina.config";

const start = async () => {
  await buildIncremental(config);
};

start();

npx herina build-incremental 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:

• incremental/*.js
• versions.json

Download Updates #

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

checkForUpdate(): Promise<boolean>

After checking the version, call requestIncrementalUpdates to download chunks whose version number is bigger than the current.

requestIncrementalUpdates(): Promise<boolean>;

Apply Update #

Finally, call applyIncrementalUpdate to generate a new bundle to replace the original one.

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

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

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

isIncrementalUpdateAvailable(): Promise<boolean>;
