testing module resolver usage with deprecated function

deprecated-with-module-resolver

testing module resolver usage to fix deprecated issue in react-native based on discussion in related react-native issue link

Step 1

Install the plugin

npm install --save-dev babel-plugin-module-resolver deprecated-react-native-prop-types

or

yarn add --dev babel-plugin-module-resolver deprecated-react-native-prop-types

Step 2

create index.js file inside project folder resolver/react-native/ with following code

import * as StandardModule from 'react-native';

const deprecatedProps = {
  ImagePropTypes: require('deprecated-react-native-prop-types/DeprecatedImagePropType'),
  TextPropTypes: require('deprecated-react-native-prop-types/DeprecatedTextPropTypes'),
  ViewPropTypes: require('deprecated-react-native-prop-types/DeprecatedViewPropTypes'),
  ColorPropType: require('deprecated-react-native-prop-types/DeprecatedColorPropType'),
  EdgeInsetsPropType: require('deprecated-react-native-prop-types/DeprecatedEdgeInsetsPropType'),
  PointPropType: require('deprecated-react-native-prop-types/DeprecatedPointPropType'),
};


// Had to use a proxy because ...StandardModule made think react-native that all modules were
// being used and was triggering some unnecessary validations / native dep checks.
// This prevents that from happening.
const objProx = new Proxy(StandardModule, {
  get(obj, prop) {
    if (prop in deprecatedProps) {
      return deprecatedProps[prop];
    }
    if (prop === 'Image') {

      return new Proxy(obj[prop], {
        get(obj, prop) {
          if (prop === 'propTypes') return deprecatedProps.ImagePropTypes;
          return Reflect.get(...arguments);
        },
      });;
    }
    if (prop === 'Text') {

      return new Proxy(obj[prop], {
        get(obj, prop) {
          if (prop === 'propTypes') return deprecatedProps.TextPropTypes;
          return Reflect.get(...arguments);
        },
      });
    }
    return Reflect.get(...arguments);
  },
});

module.exports = objProx;

Step 3

configure module resolver inside babel.config.js, depends on your project requirement to blacklist/whitelist certain npm packages to prevent conflicting file.

example module-resolver config :

var path = require('path');

module.exports = {
  presets: ['module:metro-react-native-babel-preset'],
  plugins: [
    ["module-resolver", {
      "root": ["."],
      resolvePath(sourcePath, currentFile, opts) {
        if (
          sourcePath === 'react-native' &&
          !(
            (
              currentFile.includes('node_modules/react-native/') || // macos/linux paths
              currentFile.includes('node_modules\\react-native\\')
            ) // windows path
          ) &&
          !(
            currentFile.includes('resolver/react-native/') ||
            currentFile.includes('resolver\\react-native\\')
          )
        ) {
          return path.resolve(__dirname, 'resolver/react-native');
        }
        /**
         * The `opts` argument is the options object that is passed through the Babel config.
         * opts = {
         *   extensions: [".js"],
         *   resolvePath: ...,
         * }
         */
        return undefined;
      }
    }],
 
  ],
};
