Add baseDir option, add -b flag to cli options to specify base path

[jesseditson]

node-ecstatic allows for a baseDir option, which I was looking to use with this lib.
This PR adds the following:

• a baseDir option to the main lib file
• a -b flag to the cli tool
• a path variable to printed/opened URLs
• CLI and README docs for baseDir and flag
• tests for new baseDir option

Fixes #139

[jesseditson]

Rebased in case this becomes mergeable - @indexzero LMK if I should keep this branch in sync or if we should close this PR, thanks!

[hikumealan]

This is the same as #395 - hope the feature is available soon.

[BigBlueHat]

This needs rebasing on top of the latest from master, but I generally prefer it (because tests, etc) to what's in #395.

If someone wants to get this up to speed with the latest from master, I'm 👍 on merging it.

[jesseditson]

All set. Noticed the paths weren't printing to the logs, so I added that too.

[BigBlueHat]

Hrm... -b conflicts with #463. @thornjad we should be careful about our shorthand choices probably... #395 also used -b. Thinking baseDir setting will be more frequently used, so maybe we use -b here, and remove the alias from #463.

[thornjad]

@BigBlueHat yeah that makes sense, 'b' is a popular letter. Brotli can be --brotli only

[thornjad]

Alright, @idmontie's #395 and @jesseditson's #294 have a one-line difference. I'm going to go with #294 because it came first

[thornjad]

This branch is a bit behind master, and there are a few change still scheduled (like #131) which will happen before this PR merges

[jesseditson]

I'll fix this up tonight (PST) and rebase against master!

[jesseditson]

Ok I think this is up to date, LMK if there's anything else needed on my end!

[culmat]

Would it be possible to split the change into

1. introduce feature and --base-dir flag in a 12.x minor version
2. default -b from --brotli to --base-dir in 13.x

The implementation seams ready and the functionality is requested ( see #139 ) since years.
My use case is SPA with client side routing in 404.html on github pages.
It would love to clean up my code ( dev mode work around ) as soon as this is available.

[bishtawi]

Is this PR going to be merged any time soon? Would love to be able to use this functionality.

[cattermo]

Oh, please, is there any way one can help to get this merged?

[thornjad]

Requirements for merging:

• Add documentation to doc/http-server.1
• Wait for Ecstatic with tests #693 to merge (because it will likely cause conflicts)
• Fix all conflicts

[jesseditson]

This has long fallen off of my radar (I filed this PR 5 years ago and no longer have a dependency on this lib), happy to fix conflicts if a different interested party wants to get the docs going.

[abbeysside]

Is this still an open feature?

I was trying to implement http-server with a base path but the -b flag is used for brotli now...

@thornjad @jesseditson
As this PR is 6 years old and (as one might expect) has gone stale, I rebased, fixed merge conflicts and made a new PR here: #837

Can this be merged? We do need this feature. Thanks!

[KernelDeimos]

Merged #837 because it was more recent (less conflicts) and had fewer whitespace-only changes.
