Tinybase fails to build with Browserify

[shaneosullivan]

Describe the bug

When adding an import "tinybase" or require("tinybase") in a file that is then passed to Browserify for buliding, it fails with the error

Error: Can't walk dependency graph: Cannot find module 'tinybase' 

Perhaps it is related to bundler requirements, but I build by app with many other packages and they all work just fine.

nice issue; let me take a look

OK, so I think there are two problems.

First is that Browserify doesn't seem to support the modern exports field (see https://github.com/browserify/browserify/issues/1995).

So I got around that by specifying the path directly - with require("tinybase/lib/umd/tinybase"); - to get to the UMD version of the library.

Secondly, Browserify does not seem particularly happy with the ??= nullish assignment operator, which is pretty recent. Until it knows about that, you'll need to transform ahead of time.

I did this with Babel by installing this:

npm install --save-dev babelify @babel/core @babel/preset-env

...and then adding -g [ babelify --presets [ @babel/preset-env ] ] to the command line. The spaces are significant.

When run:

$ node output.js 
{ greeting: { hi: 'there!' } }
