Built-in plugin for babel, which can be used for ssr and debugging. It inserts a name of a unit, inferred from variable name and sid (stable identifier), computed from location in the source code.

For example, in case of effects without handlers, it will improve error message by clearly showing in which effect error happened.

import {createEffect} from 'effector'
const fetchFx = createEffect()
// => no handler used in fetchFx

Try it


In the simplest case, it can be used without any configuration:

"plugins": ["effector/babel-plugin"]
