# import/no-dynamic-require: Forbid `require()` calls with expressions
|
||
|
|
|
||
|
|
The `require` method from CommonJS is used to import modules from different files. Unlike the ES6 `import` syntax, it can be given expressions that will be resolved at runtime. While this is sometimes necessary and useful, in most cases it isn't. Using expressions (for instance, concatenating a path and variable) as the argument makes it harder for tools to do static code analysis, or to find where in the codebase a module is used.
|
||
|
|
|
||
|
|
This rule checks every call to `require()` that uses expressions for the module name argument.
