Actually support overriding default options

[philschatz]

Thank you for a great library!

At a glance, the current code looks like it would work but xtend does not modify the first argument; it always returns a new object.

I ran into this because I wanted to override the IndexedDB name used so I can query for indexes other than the primary key as part of a Serverless Issue-tracking Board side-project.

Oh, you also wrote voxel.js! A couple years ago I dabbled making a 2-D+ video game that ended up using voxel.js. Examples:

• Simple Level (source)
• Level Editor (source)

And, it seems like you might be in Portland; want to grab ☕ some time?

Oh, it looks like you're looking for a ticket tracker! Here's a link that combines Issues from multiple repositories and uses a custom RegExp for determining which labels to use as columns: http://philschatz.com/gh-board/#/r/maxogden:dat|level.js|mafintosh:hyperdrive|substack:level-party?x=[a-z] (you can always npm start locally if you don't trust gh-pages with a token)

Some other side-projects:

• forkable CC-BY textbooks - blog posts one and two
• octokat.js - JS client for GitHub's API
• atom-pull-requests - show Pull Request comments directly in atom
• electon-init - boilerplate for an electron app using conventions from the Atom Flight Manual

@vweevers Should we pull this functionality in by another PR?

[vweevers]

It will probably change if and when we remove idbwrapper. Let's keep this open as a reminder.

@philschatz this is old, but can you explain what you meant by:

Closing this because of #88. Feel free to open a new issue if your use case isn't covered.

@vweevers It has been a few years since I looked at this code but I think that xtend(firstArg, secondArg) does not modify firstArg but rather it returns a new object.

Therefore, there was no way to change the arguments that were passed in when constructing a new IDB(idbOpts). I think I had wanted to change one of the defaults listed in https://github.com/Level/level.js/pull/53/files#diff-168726dbe96b3ce427e7fedce31bb0bcR23

Hope that helps!

PS: Here is the code that used level.js: https://github.com/philschatz/gh-board/blob/458766d075664d65e53f8841c39b8ad04b8ee402/src/database.js#L103-L109 and https://github.com/philschatz/gh-board/blob/458766d075664d65e53f8841c39b8ad04b8ee402/src/github-client.js#L44-L56

@philschatz Thanks! We've since removed IDBWrapper, so there are no idbOpts anymore. But we'll write an upgrade guide, so if and when you update your code you should be able to map old options to new. All the options I see in your gh-board code are supported (in a different form) except for indexes.
