[v2] [unconfirmed] Gatsby doesn't properly delete files on build

[vtenfys]

@dfmarulanda has pointed out that gatsby build doesn't work reliably without first deleting the public folder - we should guarantee that running gatsby build over an existing build results in a working website.

Just checked this on the latest commit of crowdswap/landing - I cloned, ran yarn install and gatsby serve and upon visiting localhost:9000, there were no problems.

@dfmarulanda I'm assuming this is a problem with how Azure is caching certain resources, since it's working perfectly for me - closing. Please let me know if you have any further issues, but I think this is an issue with your deployment rather than with Gatsby.

[vtenfys]

OK. I'll try to change my deploy process. It's super easy to do it using netlify, aws, heroku, but there is no an azure plugin. There is a docker plugin working in the latest version of Gatsby?

@dfmarulanda (please make further replies in this issue, rather than #7355) I did some investigating and I think the issue could be caused by Azure not updating all the pages, rather than Gatsby - theoretically it should work if Azure deploys the public folder in git, since it works fine locally with your latest commit, without deleting or creating any files.

[vtenfys]

Having said that, I'd still recommend you try to build the site on Azure, rather than your current approach, since it would make the git repo easier to manage.

This sounds like a bad npm/yarn install problem. The only possible issue with files in public is if you remove a page and then don't delete the html for that page. But we take care of that by deleting all HTML files at the start of a build.

[dfmarulanda]

I deleted everything, indeed it worked perfectly for weeks. I changed my deployment process and now it's working perfectly. I decided to use Azure Blob Storage instead of Azure Web App. Working like a charm.

I don't know but I just looked into my public folder and was huge of .map and .js.map files. I don't think they get wiped all the time properly.

@hackhat that's very good point, we should expand globs used in

gatsby/packages/gatsby/src/bootstrap/index.js

Lines 133 to 148 in 42a2d07

	// Delete html and css files from the public directory as we don't want
	// deleted pages and styles from previous builds to stick around.
	activity = report.activityTimer(
	`delete html and css files from previous builds`,
	{
	parentSpan: bootstrapSpan,
	}
	)
	activity.start()
	await del([
	`public/*.{html,css}`,
	`public/**/*.{html,css}`,

	activity.end()
