Doesn't work with typescript 5

Error: createNode is not a function

Have you considered to use https://github.com/timocov/ts-transformer-properties-rename instead? I recently upgraded it to support typescript 5 and it is able to do exactly the same as this transformer does (and even more), so I'm curious what could be a reason not to use it. Will wait for your feedback.

@timocov I've tried to use https://github.com/timocov/ts-transformer-properties-rename but couldn't make it work.

How I use ts-transformer-minify-privates in webpack ts-loader:

import:

import minifyPrivatesTransformer from 'ts-transformer-minify-privates';

use in ts-loader rule:

    {
        loader: 'ts-loader',
        options: {
            transpileOnly,
            onlyCompileBundledFiles: true,
            compilerOptions: {
                target: `es${targetEsVersion}`,
                importHelpers: true,
                jsx: 'preserve',
                noUnusedLocals: false
            },
            getCustomTransformers: transpileOnly ?
                undefined :
                (program: ts.Program) => ({
                    before: [
                        minifyPrivatesTransformer(program)
                    ]
                })
        }
    }

How I try to use ts-transformer-properties-rename:

const propertiesRenameTransformer = require('ts-transformer-properties-rename').default;

First of all, It's weird ts-transformer-properties-rename doesn't include d.ts for types. Then I replace transform with the new one. Now I have to pass some entrySourceFiles (with ts-transformer-minify-privates I don't). Ok, I try to pass the same entry file as I pass to webpack entry:

propertiesRenameTransformer(program, { entrySourceFiles: [entryFile] })

And get an error: Error: Cannot find source file /Users/dfilatov/prjs/arcadia/maps/front/services/nmaps/src/client/pages/app-page/nk-app-page.ts

But file /Users/dfilatov/prjs/arcadia/maps/front/services/nmaps/src/client/pages/app-page/nk-app-page.ts actually exists:

❯ ls -la /Users/dfilatov/prjs/arcadia/maps/front/services/nmaps/src/client/pages/app-page/nk-app-page.ts

Have no idea how to make it work. Please help.

@dfilatov thanks for detailed explanation, I appreciate it! I've updated this transformer to make it work with the latest typescript version in https://github.com/timocov/ts-transformer-minify-privates/releases/tag/v1.0.0 release and unblock your work. Meanwhile I'll use your feedback to improve https://github.com/timocov/ts-transformer-properties-rename and make transition from to it smoother.

@timocov Now it works great, thank you!
