🐛 --public-url is setted on build and watch

[corlaez]

When I work with parcel index.html the resulting files have public-url set to ./, when I use build or watch the public url is no longer ./ but ./build.

Reproducing the error:

https://github.com/lrn2prgrm/parcel-bug/tree/master

🎛 Configuration (.babelrc, package.json, cli command)

{
"name": "cli",
"version": "1.0.0",
"license": "MIT",
"scripts": {
"dev-serve": "parcel src/index.html -d build --no-cache",
"watch": "parcel watch src/index.html -d build --no-cache",
"build": "parcel build src/index.html -d build --no-minify --no-cache",
"start": "yarn build"
},
"devDependencies": {
"parcel-bundler": "^1.5.1",
"typescript": "^2.6.2"
}
}

🤔 Expected Behavior

watch and build produced files should be generated as if public url is ./

either with

• "prestart": "yarn build",
• "prestart": "yarn watch",

dev-serve behaves correctly

😯 Current Behavior

watch and build produced files should be generated as if public url is ./build

either with

• "prestart": "yarn build",
• "prestart": "yarn watch",

dev-serve behaves correctly

💁 Possible Solution

No idea about implementation but the code that adds this public url should be found and modified

Found as I closed this issue thanks to niicojs: #706

I realise I am defining an output directory, at the moment this flag is being interpreted could be when the default url is getting setted.

I also think that this behaviour is somewhat unexpected, though I know that changing it would be a breaking change, I think it should be considered.

I think this is a more a RFC than a bug.
When using serve we set the public-url because we are in charge of serving files over HTTP. I don't see any use-case where serve + --public-url is used.
When using build or watch the public-url is the out-dir by default.

But I agree that using anything else than / by default for the public-url is confusing as IMHO most people expect a build dir with a index.html and resources served on the same directory.

Couldn't agree more, for most I would imagine that this is far from the expected behaviour.
