Query Support Proposal about dynamodb-toolbox HOT 7 CLOSED

Not yet, @clarkd. But you can just run npm install jeremydaly/dynamodb-toolbox#v0.2 to install v0.2 as a dependency.

Queries are now supported on the v0.2 branch.

@cameroncf, this is great work! There is a lot to unpack here, but my overall goals for this library include mapping multiple entities to a single table design, and enabling access patterns through the use of config-based mappings (all with caveat that I don't want this to be an ORM). However, using GSIs and encapsulating/automating known patterns for both read and write scenarios, absolutely have to exist.

I really like this idea of interpolating (if you'd call it that) queries, by looking at the model to assume access patterns. I was thinking more along the lines of defining/naming access patterns manually, e.g. Employee.getByEmail('[email protected]'). The thought was that you could build out these access patterns and provide them to developers through your data abstraction layer. There would need to be (I think) some basic things out of the box, though. And your idea could definitely be one of those things.

I'm envisioning the "write" process having more tools for index manipulation as well, because there needs to be an easier way to correctly assemble GSI pks and sks that's based on the input.

Thanks again for this! I'll definitely be incorporating these ideas into the next version.

@jeremydaly - Just discovered your v0.2 branch, which looks to be a start at some additional ideas. I'm still digesting but really like this tool so far. Thanks for all the hard work on it!

FYI, queries have been implemented in v0.2 as a high level abstraction. This allows for fast and easy query creation, which should be a building block for adding something more advanced like your above proposal. Lots of work left to do, but getting closer.

Is 0.2 available on NPM or anywhere? I realise it's not quite there yet but would good to experiment with...

Thanks - will take a look!
