max-dependencies

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).

Options

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}]

Example

Given a max value of {"max": 2}:

Fail

import a from './a'; // 1
const b = require('./b'); // 2
import c from './c'; // 3 - exceeds max!

Pass

import a from './a'; // 1
const anotherA = require('./a'); // still 1
import {x, y, z} from './foo'; // 2

When Not To Use It

If you don't care how many dependencies a module has.
