yarn start-storybook => freeze on 95% emitting fork-ts-checker-webpack-plugin

Describe the bug Everything is in the issue title

To Reproduce I’m on fresh new angular 10 project. I am in the setup phase preparing all the necessary tools before starting the development.

Just to mentioned that I used Storybook for two previous projects based on Web Components and I did not meet issues.

So, based on an fresh new angular 10 project:

1. I installed storybook from the CLI command in my fresh angular project.
2. To test the install, I ran the command below (automatically added by storybook during its setup in my package.json): npm run storybook => the besides command is yarn start-storybook -p 6006 from the package.json
3. Everything compiled fine and the web page is opened as well in my browser… So it’s OK until then
4. I made a change in the file stories/Button.stories.ts (also an example file added by storybook during setup). I just changed the Button label property in the Primary story. Nothing more.
5. The start-storybook watcher detected my change and recompile as expected. And my change appeared in the browser.
6. I made the same change, in the same file on the same property… And… the issue appeared 95% emitting fork-ts-checker-webpack-plugin
7. The prompt is frozen and does not exit. I have to Ctrl+c to force exit.

And the issues is reproduced each time on the second build pass after a second change I made in any file after the storybook server startup. The first pass always seems to work.

I tried to disable the typescript checker as mentioned in storybook documentation in .storybook/main.js (See here):

module.exports = {
  typescript: {
    check: false,
    checkOptions: {},
  }
};

But it seems that this setup snippet is not taken into account by the build… I tried other setup from fork-ts-checker-webpack-plugin package with fork-ts-checker config files, fork-ts-checker setup in package.json to enable logging, increase memory… But nothing seems to have an effect…

Expected behavior Finish the build and refresh the storybook web page in the browser.

Screenshots ==> Idle after storybook server launch

==> First build pass OK after a first change made in a story source file sample stories/Button.stories.ts

==> Second build pass freezes !!! After the same change made in the same story source file sample stories/Button.stories.ts

FYI: I have this problem with WebStorm & Angular 🤔.

I was getting the same problem after re configuring my .vimrc for use with neovim, storybook, and angular. I went through my old settings and managed to narrow down the problem.

Adding these 2 line to my .vimrc seemed to solve the issue for me:

set nobackup      " No autocreation of backup files
set nowritebackup " No autocreation of backup files
