# 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.
|
||
|
|
||
|
## Rule Details
|
||
|
|
||
|
### Fail
|
||
|
|
||
|
```js
|
||
|
require(name);
|
||
|
require('../' + name);
|
||
|
require(`../${name}`);
|
||
|
require(name());
|
||
|
```
|
||
|
|
||
|
### Pass
|
||
|
|
||
|
```js
|
||
|
require('../name');
|
||
|
require(`../name`);
|
||
|
```
