Forbid modules to have too many dependencies (import
or require
statements).
This is a useful rule because a module with too many dependencies is a code smell, and usually indicates the module is doing too much and/or should be broken up into smaller modules.
Importing multiple named exports from a single module will only count once (e.g. import {x, y, z} from './foo'
will only count as a single dependency).
This rule takes the following option:
max
: The maximum number of dependencies allowed. Anything over will trigger the rule. Default is 10 if the rule is enabled and no max
is specified.
You can set the option like this:
"import/max-dependencies": ["error", {"max": 10}]
Given a max value of {"max": 2}
:
import a from './a'; // 1
const b = require('./b'); // 2
import c from './c'; // 3 - exceeds max!
import a from './a'; // 1
const anotherA = require('./a'); // still 1
import {x, y, z} from './foo'; // 2
If you don't care how many dependencies a module has.
