rollup-plugin-extension-order v1.0.0

rollup-plugin-extension-order

a rollup plugin for extension order

Intro

Suppose we have the following import defined in a hypothetical file:

import { storeData } from "./storage";

with function：storage management in it

// storage/index.ts
export function storeData(storeKey: string, data: any) {
  try {
    wx.setStorageSync(storeKey, data);
  } catch (e) {
    console.error(e);
  }
}

It may run well in wechat, but not in alipay

We can try solve it by giving another file:

// storage/index.aliapp.ts
export function storeData(storeKey: string, data: any) {
  try {
    my.setStorageSync({
      key: storeKey,
      data,
    });
  } catch (e) {
    console.error(e);
  }
}

This plugin will help resolve import issues and generate files in dist/

if build with plateform "" or "weapp":

output will use plain import guide

if build with plateform "aliapp":

output will try files which extension name contains ".aliapp.ts" or ".aliapp.js", then try ".ts" or ".js"

Requirements

This plugin requires an LTS Node version (v14.17.6+) and Rollup v2.38.5+.

Install

Using npm:

npm install rollup-plugin-extension-order --save-dev
# or
yarn add -D rollup-plugin-extension-order

Usage

Create a rollup.config.js configuration file and import the plugin:

import extensionOrder from "rollup-plugin-extension-order";

module.exports = {
  input: "src/index.js",
  output: {
    dir: "output",
    format: "cjs",
  },
  plugins: [extensionOrder([".aliapp.ts", ".aliapp.js", ".ts", ".js"])],
};

Then call rollup either via the CLI or the API. If the build produces any errors, the plugin will write a 'extension-order' character to stderr, which should be audible on most systems.
