# import/dynamic-import-chunkname
|
||
|
|
|
||
|
|
This rule reports any dynamic imports without a webpackChunkName specified in a leading block comment in the proper format.
|
||
|
|
|
||
|
|
This rule enforces naming of webpack chunks in dynamic imports. When you don't explicitly name chunks, webpack will autogenerate chunk names that are not consistent across builds, which prevents long-term browser caching.
|
||
|
|
|
||
|
|
## Rule Details
|
||
|
|
This rule runs against `import()` by default, but can be configured to also run against an alternative dynamic-import function, e.g. 'dynamicImport.'
|
||
|
|
You can also configure the regex format you'd like to accept for the webpackChunkName - for example, if we don't want the number 6 to show up in our chunk names:
|
||
|
|
```javascript
|
||
|
|
{
|
||
|
|
"dynamic-import-chunkname": [2, {
|
||
|
|
importFunctions: ["dynamicImport"],
|
||
|
|
webpackChunknameFormat: "[a-zA-Z0-57-9-/_]+"
|
||
|
|
}]
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### invalid
|
||
|
|
The following patterns are invalid:
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
// no leading comment
|
||
|
|
import('someModule');
|
||
|
|
|
||
|
|
// incorrectly formatted comment
|
||
|
|
import(
|
||
|
|
/*webpackChunkName:"someModule"*/
|
||
|
|
'someModule',
|
||
|
|
);
|
||
|
|
import(
|
||
|
|
/* webpackChunkName : "someModule" */
|
||
|
|
'someModule',
|
||
|
|
);
|
||
|
|
|
||
|
|
// chunkname contains a 6 (forbidden by rule config)
|
||
|
|
import(
|
||
|
|
/* webpackChunkName: "someModule6" */
|
||
|
|
'someModule',
|
||
|
|
);
|
||
|
|
|
||
|
|
// invalid syntax for webpack comment
|
||
|
|
import(
|
||
|
|
/* totally not webpackChunkName: "someModule" */
|
||
|
|
'someModule',
|
||
|
|
);
|
||
|
|
|
||
|
|
// single-line comment, not a block-style comment
|
||
|
|
import(
|
||
|
|
// webpackChunkName: "someModule"
|
||
|
|
'someModule',
|
||
|
|
);
|
||
|
|
```
|

|
|

|
||
|
|
'someModule',
|
||
|
|
);
|
||
|
|
|
||
|
|
// using single quotes instead of double quotes
|
||
|
|
import(
|
||
|
|
/* webpackChunkName: 'someModule' */
|
||
|
|
'someModule',
|
||
|
|
);
|
||
|
|
```
|
||
|
|
|
||
|
|
## When Not To Use It
|
||
|
|
|
||
|
|
If you don't care that webpack will autogenerate chunk names and may blow up browser caches and bundle size reports.
