| # Forbid import of modules using absolute paths | ||
|
|
||
| Node.js allows the import of modules using an absolute path such as `/home/xyz/file.js`. That is a bad practice as it ties the code using it to your computer, and therefore makes it unusable in packages distributed on `npm` for instance. | ||
|
|
||
| ## Rule Details | ||
|
|
||
| ### Fail | ||
|
|
||
| ```js | ||
| import f from '/foo'; | ||
| import f from '/some/path'; | ||
|
|
||
| var f = require('/foo'); | ||
| var f = require('/some/path'); | ||
| ``` | ||
|
|
||
| ### Pass | ||
|
|
||
| ```js | ||
| import _ from 'lodash'; | ||
| import foo from 'foo'; | ||
| import foo from './foo'; | ||
|
|
||
| var _ = require('lodash'); | ||
| var foo = require('foo'); | ||
| var foo = require('./foo'); | ||
| ``` |
