default typescript plugin conflicts with ts-loader

[Merciful12]

Description

i use ts loader and after i updated gatsby i start getting errors like this #26027
I Didn't catch how to disable default babel ts compilation #26452

Steps to reproduce

start a new gatsby project and add ts-loader plugin

Expected result

should build without error

Actual result

didn't build because errors like

TS2683: 'this' implicitly has type 'any' because it does not have a type annotation.
TS7006: Parameter '_ref3' implicitly has an 'any' type.

There is (supposed to be) discussion about modifying the default typescript loader here: #26984. It hasn't seen any action since that PR, however.

For right now, in onCreateWebpackConfig, you would need to strip out gatsby-plugin-typescript in order for you to be able to use ts-loader.

@Js-Brecht For temporary solution i just resolve both plugins in order : gatsby-plugin-typescript, gatsby-plugin-ts-loader. And it works fine. How to strip out in onCreateWebpackConfig?

[Js-Brecht]

You would need to find the rule in the webpack config that matches against *.ts files and that uses babel-loader, and remove it. That should leave the rule that uses ts-loader

I'll close this in favor of #26984

Thanks Js-Brecht for always helping out!
