no-missing-require.md

Disallow require() expressions which import non-existence modules (n/no-missing-require)

💼 This rule is enabled in the following configs: 🟢 recommended-module, ✅ recommended-script.

Maybe we cannot find typo of import paths until run it, so this rule checks import paths.

// If the file "foo" doesn't exist, this is a runtime error.
const foo = require("./foo");

📖 Rule Details

This rule checks the file paths of require()s, then reports the path of files which don't exist.

Examples of 👎 incorrect code for this rule:

/*eslint n/no-missing-require: "error" */

var typoFile = require("./typo-file");   /*error "./typo-file" is not found.*/
var typoModule = require("typo-module"); /*error "typo-module" is not found.*/

Examples of 👍 correct code for this rule:

/*eslint n/no-missing-require: "error" */

var existingFile = require("./existing-file");
var existingModule = require("existing-module");

// This rule cannot check for dynamic imports.
var foo = require(FOO_NAME);
