This example reads in an object or array from `my.config.js` and passes it into the `ConfigArray` constructor as the first argument. The second argument is an object specifying the `basePath` (the directoy in which `my.config.js` is found) and a `schema` to define the additional properties of a config object beyond `files`, `ignores`, and `name`.

### Specifying a Schema
|
||||
|
||||
The `schema` option is required for you to use additional properties in config objects. The schema is object that follows the format of an [`ObjectSchema`](https://npmjs.com/package/@humanwhocodes/object-schema). The schema specifies both validation and merge rules that the `ConfigArray` instance needs to combine configs when there are multiple matches. Here's an example:

|
||||
|
||||
You can also specify an `ignores` key that will force files matching those patterns to not be included. If the `ignores` key is in a config object without any other keys, then those ignores will always be applied; otherwise those ignores act as exclusions. Here's an example:
|
||||
|
||||
```js
|
||||
export default [
|
||||
|
||||
// Always ignored
|
||||
{
|

ignores: ["**/.git/**", "**/node_modules/**"]

||||
handler: jsHandler
|
||||
}
|
||||
];
|
||||
```
|
||||
|
||||
You can use negated patterns in `ignores` to exclude a file that was already ignored, such as:
|
||||
|
||||
```js
|
||||
export default [

||||
|
||||
// Ignore all JSON files except tsconfig.json

{

files: ["**/*"],

ignores: ["**/*.json", "!tsconfig.json"]

},

];
|
||||
```
|

|
||||
### Config Functions
|
||||
|
||||
Config arrays can also include config functions. A config function accepts a single parameter, `context` (defined by you), and must return either a config object or a config array (it cannot return another function). Config functions allow end users to execute code in the creation of appropriate config objects. Here's an example:

The `normalize()` method returns a promise, so be sure to use the `await` operator. The config array instance is normalized in-place, so you don't need to create a new variable.
|
||||
|
||||
If you want to disallow async config functions, you can call `normalizeSync()` instead. This method is completely synchronous and does not require using the `await` operator as it does not return a promise:
|
||||
|
||||
```js
|
||||
await configs.normalizeSync({
|
||||
name: "MyApp"
|
||||
});
|
||||
```

|
||||
**Important:** Once a `ConfigArray` is normalized, it cannot be changed further. You can, however, create a new `ConfigArray` and pass in the normalized instance to create an unnormalized copy.

### Getting Config for a File

@ -244,6 +288,46 @@ A few things to keep in mind:
|
|||
* You must pass in the absolute filename to get a config for.
|
||||
* The returned config object never has `files`, `ignores`, or `name` properties; the only properties on the object will be the other configuration options specified.
|
||||
* The config array caches configs, so subsequent calls to `getConfig()` with the same filename will return in a fast lookup rather than another calculation.
|
||||
* A config will only be generated if the filename matches an entry in a `files` key. A config will not be generated without matching a `files` key (configs without a `files` key are only applied when another config with a `files` key is applied; configs without `files` are never applied on their own). Any config with a `files` key entry ending with `/**` or `/*` will only be applied if another entry in the same `files` key matches or another config matches.
|
||||
|
||||
## Determining Ignored Paths
|
||||
|
||||
You can determine if a file is ignored by using the `isFileIgnored()` method and passing in the absolute path of any file, as in this example:
|
||||
|
||||
```js
|
||||
const ignored = configs.isFileIgnored('/foo/bar/baz.txt');
|
||||
```
|
||||
|
||||
A file is considered ignored if any of the following is true:
|
||||
|
||||
* **It's parent directory is ignored.** For example, if `foo` is in `ignores`, then `foo/a.js` is considered ignored.
|
||||
* **It has an ancestor directory that is ignored.** For example, if `foo` is in `ignores`, then `foo/baz/a.js` is considered ignored.
|
||||
* **It matches an ignored file pattern.** For example, if `**/a.js` is in `ignores`, then `foo/a.js` and `foo/baz/a.js` are considered ignored.
|
||||
* **If it matches an entry in `files` and also in `ignores`.** For example, if `**/*.js` is in `files` and `**/a.js` is in `ignores`, then `foo/a.js` and `foo/baz/a.js` are considered ignored.
|
||||
* **The file is outside the `basePath`.** If the `basePath` is `/usr/me`, then `/foo/a.js` is considered ignored.
|
||||
|
||||
For directories, use the `isDirectoryIgnored()` method and pass in the absolute path of any directory, as in this example:
|
||||
|
||||
```js
|
||||
const ignored = configs.isDirectoryIgnored('/foo/bar/');
|
||||
```
|
||||
|
||||
A directory is considered ignored if any of the following is true:
|
||||
|
||||
* **It's parent directory is ignored.** For example, if `foo` is in `ignores`, then `foo/baz` is considered ignored.
|
||||
* **It has an ancestor directory that is ignored.** For example, if `foo` is in `ignores`, then `foo/bar/baz/a.js` is considered ignored.
|
||||
* **It matches and ignored file pattern.** For example, if `**/a.js` is in `ignores`, then `foo/a.js` and `foo/baz/a.js` are considered ignored.
|
||||
* **If it matches an entry in `files` and also in `ignores`.** For example, if `**/*.js` is in `files` and `**/a.js` is in `ignores`, then `foo/a.js` and `foo/baz/a.js` are considered ignored.
|
||||
* **The file is outside the `basePath`.** If the `basePath` is `/usr/me`, then `/foo/a.js` is considered ignored.
|
||||
|
||||
**Important:** A pattern such as `foo/**` means that `foo` and `foo/` are *not* ignored whereas `foo/bar` is ignored. If you want to ignore `foo` and all of its subdirectories, use the pattern `foo` or `foo/` in `ignores`.
|
||||
|
||||
## Caching Mechanisms
|
||||
|
||||
Each `ConfigArray` aggressively caches configuration objects to avoid unnecessary work. This caching occurs in two ways:
|
||||
|
||||
1. **File-based Caching.** For each filename that is passed into a method, the resulting config is cached against that filename so you're always guaranteed to get the same object returned from `getConfig()` whenever you pass the same filename in.
|
||||
2. **Index-based Caching.** Whenever a config is calculated, the config elements that were used to create the config are also cached. So if a given filename matches elements 1, 5, and 7, the resulting config is cached with a key of `1,5,7`. That way, if another file is passed that matches the same config elements, the result is already known and doesn't have to be recalculated. That means two files that match all the same elements will return the same config from `getConfig()`.
