Cypress may conflict with a user project's .babelrc file

[paulfalgout]

Updating to 0.18 seemingly removed my node_modules folder for my project which I found odd. Attempting to run Cypress gave the error Error: Couldn't find preset "es2015" relative to directory...

After running npm i things seem to be working, but I'm not sure if this is because my library happens to include babel-preset-es2015. If my project did not rely on babel would this have worked?

This may be an oddity of the update and not a bug, but reporting in case it is a larger issue. For the moment, everything is ok on my end.

Do you have a .babelrc file or have babel configured in your package.json?

[paulfalgout]

I have a .babelrc in the parent directory of cypress/

We added babel support in 0.18.0, but we didn't intend to auto-load your .babelrc file. It seems babel does that by default. We intend to add babel configuration support via .babelrc or cypress.json in a future release, but haven't gotten into that yet, so we haven't tested anything regarding .babelrc out. I guess we get .babelrc support for free haha.

If your project didn't have a .babelrc, it should have just worked, because we include default settings for babel so everything works out of the box. Or if your node_modules had not been removed, you of course would not have needed to npm install to get things working.

Your node_modules directory being removed is the real concerning part. That should not be happening, so we'll be looking into that.

Thanks for reporting this issue!

Cool.
I'm 100% sure that occurred in the update too.. I was running a gulp process using node_modules when I saw the cypress update. There were minutes between running gulp successfully and updating cypress and having my node_modules folder disappear :-) I don't have any other process that cleans out the dir.

Fixed in 0.18.1.
