etag
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 module available through the
npm registry. Installation is done using the
npm install command:
$ npm install @robireton/etagAPI
import etag from '@robireton/etag'etag(entity, [options])
Generate a strong ETag for the given entity. This should be the complete
body of the entity. Strings, Buffers, 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).
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.
