A browserify transform that allows optional dependencies in try..catch blocks
npm install browserify-optionalIt is a common pattern in Node to support optional dependencies via requires in try..catch blocks.
Browserify doesn't support this by default and throws a compile time error when it cannot find a
module. You can solve the problem by using browserify's exclude option, but this works globally
instead of at a per-module level. This transform fixes the problem by moving the compile time
error to a runtime error for requires of missing modules inside try..catch blocks.
The transform would transform the following code such that requiring missing-module would throw
a runtime error instead of a compile time error, making the code work as expected.
``javascript`
try {
var x = require('missing-module');
} catch (e) {
var x = require('replacement-module');
}
To set it up in browserify, add this to your package.json:
`json``
"browserify": {
"transform": ["browserify-optional"]
}
