TypeScript Custom Code Transformer does not work

[unlight]

Install instruction to setup TypeScript Custom Code Transformer https://github.com/rimeto/ts-optchain#typescript-custom-code-transformer

1. Using TTypescript Bundle contains

   
   /***/ "./node_modules/ts-optchain/dist/proxy/index.js":
   /*!******************************************************!*\
   !*** ./node_modules/ts-optchain/dist/proxy/index.js ***!
   \******************************************************/
   /*! no static exports found */
   /***/ (function(module, exports, __webpack_require__) {

"use strict";

/**

• This source code is licensed under the MIT license found in the
• LICENSE file in the root directory of this source tree. */ Object.defineProperty(exports, "__esModule", { value: true }); /**
• Proxy based implementation of optional chaining w/ default values. */ function oc(data) { return new Proxy((function (defaultValue) { return (data == null ? defaultValue : data); }), { get: function (target, key) { var obj = target(); return oc(typeof obj === 'object' ? obj[key] : undefined); }, }); } exports.oc = oc;

  I do not see transformed result, e.g.

  const value = (obj != null && obj.propA != null && obj.propA.propB != null && obj.propA.propB.propC != null) ? obj.propA.propB.propC : defaultValue;

2. Same result when using getCustomTransformers of ts-loader Part of webpack.config

                           getCustomTransformers: program => ({
                               before: [
                                   require('ts-optchain/transform').default(program),
                               ]
                           }),

Environment

node 12.6
+-- ts-loader@6.0.2
+-- ts-optchain@0.1.7
+-- ttypescript@1.5.7
`-- typescript@3.5.2

Same problem!

Anyone managed to solve this?

This is not an issue for me, since typescript 3.7 with optional chaining feature.
