cif / babel-plugin-auto-constant

Assign strings of the same name to simple uppercase constant expressions

Auto Constant!

This space aged babel plugin allows you to create constants whose value is the named expression by simply writing the expression without const or assigning a value:

E.g. instead of:

const FOO_UPDATE_IN_FLIGHT = 'FOO_UPDATE_IN_FLIGHT';

simply write:

FOO_UPDATE_IN_FLIGHT;

... which compiles the same to:

var FOO_UPDATE_IN_FLIGHT = 'FOO_UPDATE_IN_FLIGHT';

Exporting

If you want to export, add two underscores to the end of your expression:

FOO_LOADED__

...which will compile to

var FOO_LOADED = exports.FOO_LOADED = 'FOO_LOADED';

Note if you are only exporting constants, make sure to export a default or any value so that Babel will define the __esModule property on exports

Linting

Unfortunately I haven't made time to come up with a good way around two ESlint rules. For now you'll want to add these if you want to be lazy:

"no-unused-expressions": 0,
"no-undef": 0
