Do I still need this plugin when using babel7?

[lili21]

since babel7 already support typescript.

So I can stick with rollup-plugin-babel + babel7, right ?

I guess use @babel/preset-typescript is a better choice

It doesn't work for me when using it with rollup-plugin-babel, although works pretty fine when running babel isolated: rollup/rollup-plugin-babel#255
Seems we still need to transpile TS with rollup-plugin-typescript separately.

@zhaparoff I have already used babel + ts + react for devlopment. below is my rollup config and babel config

import babel from 'rollup-plugin-babel';
import resolve from 'rollup-plugin-node-resolve';
import commonjs from 'rollup-plugin-commonjs';
import replace from 'rollup-plugin-replace';

const extensions = [
    '.js', '.jsx', '.ts', '.tsx',
];

export default {
    input: 'src/index.ts',
    output: {
        file: 'dist.js',
        dir: 'dist',
        format: 'umd',
        sourcemap: true
    },
    plugins: [
        replace({
            'process.env.NODE_ENV': JSON.stringify(process.env.NODE_ENV)
        }),
        resolve({
            extensions
        }),
        commonjs({
            include: 'node_modules/**',
            namedExports: {
                'node_modules/react-dom/index.js': ['render'],
                'node_modules/react/index.js': ['Component', 'PropTypes', 'createElement']
            }
        }),
        babel({
            extensions,
            runtimeHelpers: true,
            exclude: 'node_modules/**' // only transpile our source code
        })
    ]
};

{
    "presets": [
        ["@babel/preset-env", {
            "modules": false,
            "loose": true,
            "debug": true,
            "useBuiltIns": "usage"
        }],
       [ "@babel/preset-typescript", {
           "isTSX": true,
           "allExtensions": true
       }],
       "@babel/preset-react"
    ],
    "plugins": ["@babel/plugin-proposal-class-properties"]
}

There some explanation about the caveats of using @babel/preset-typescript here
https://blogs.msdn.microsoft.com/typescript/2018/08/27/typescript-and-babel-7/
However, babel is still needed if you want to use macros 🎣

Hey folks (this is a canned reply, but we mean it!). Thanks to everyone who participated in this issue. We're getting ready to move this plugin to a new home at https://github.com/rollup/plugins, and we have to do some spring cleaning of the issues to make that happen. We're going to close this one, but it doesn't mean that it's not still valid. We've got some time yet before the move while we resolve pending Pull Requests, so if this issue is still relevant, please @ me and I'll make sure it gets transferred to the new repo. 🍺
