|
||||
Create simple HTTP ETags
|
||||
|
||||
This module generates HTTP ETags (as defined in RFC 7232) for use in
|
||||
HTTP responses.
|
||||
|
||||
## Installation
|
||||
|
||||
This is a [Node.js](https://nodejs.org/en/) module available through the
|
||||
[npm registry](https://www.npmjs.com/). Installation is done using the
|
||||
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
|
||||
|
||||
```sh
|
||||
$ npm install etag
|
||||
```
|
||||
|
||||
## API
|
||||
|
||||
<!-- eslint-disable no-unused-vars -->
|
||||
|
||||
```js
|
||||
var etag = require('etag')
|
||||
```
|
||||
|
||||
### etag(entity, [options])
|
||||
|
||||
Generate a strong ETag for the given entity. This should be the complete
|
||||
body of the entity. Strings, `Buffer`s, and `fs.Stats` are accepted. By
|
||||
default, a strong ETag is generated except for `fs.Stats`, which will
|
||||
generate a weak ETag (this can be overwritten by `options.weak`).
|
||||
|
||||
<!-- eslint-disable no-undef -->
|
||||
|
||||
```js
|
||||
res.setHeader('ETag', etag(body))
|
||||
```
|
||||
|
||||
#### Options
|
||||
|
||||
`etag` accepts these properties in the options object.
|
||||
|
||||
##### weak
|
||||
|
||||
Specifies if the generated ETag will include the weak validator mark (that
|
||||
is, the leading `W/`). The actual entity tag is the same. The default value
|
||||
is `false`, unless the `entity` is `fs.Stats`, in which case it is `true`.
|
||||
|
||||
## Testing
|
||||
|
||||
```sh
|
||||
$ npm test
|
||||
```
|
||||
