Ensures an imported module can be resolved to a module on the local filesystem,
as defined by standard Node require.resolve behavior.
See settings for customization options for the resolution (i.e.
additional filetypes, NODE_PATH, etc.)
This rule can also optionally report on unresolved modules in CommonJS require('./foo') calls and AMD require(['./foo'], function (foo){...}) and define(['./foo'], function (foo){...}).
To enable this, send { commonjs: true/false, amd: true/false } as a rule option.
Both are disabled by default.
If you are using Webpack, see the section on resolver plugins.
By default, only ES6 imports will be resolved:
/*eslint import/no-unresolved: 2*/
import x from './foo' // reports if './foo' cannot be resolved on the filesystemIf {commonjs: true} is provided, single-argument require calls will be resolved:
/*eslint import/no-unresolved: [2, { commonjs: true }]*/
const { default: x } = require('./foo') // reported if './foo' is not found
require(0) // ignored
require(['x', 'y'], function (x, y) { /*...*/ }) // ignoredSimilarly, if { amd: true } is provided, dependency paths for define and require
calls will be resolved:
/*eslint import/no-unresolved: [2, { amd: true }]*/
define(['./foo'], function (foo) { /*...*/ }) // reported if './foo' is not found
require(['./foo'], function (foo) { /*...*/ }) // reported if './foo' is not found
const { default: x } = require('./foo') // ignoredBoth may be provided, too:
/*eslint import/no-unresolved: [2, { commonjs: true, amd: true }]*/
const { default: x } = require('./foo') // reported if './foo' is not found
define(['./foo'], function (foo) { /*...*/ }) // reported if './foo' is not found
require(['./foo'], function (foo) { /*...*/ }) // reported if './foo' is not foundIf you're using a module bundler other than Node or Webpack, you may end up with a lot of false positive reports of missing dependencies.
