etag's direct dependencies. Data on all dependencies, including transitive ones, is available via CSV download.
To use the etag package, start by installing it through the npm registry by using the
npm install etag command in the terminal. In your code, you can require the package by using
var etag = require('etag'). You can generate an ETag for an entity (the complete body of an entity) via
etag(entity, [options]). Acceptable entities are Strings,
fs.Stats. The 'options' parameter lets you specify whether to generate a strong or weak ETag (with the weak validator mark, the leading 'W/'). By default, 'options.weak' is false, meaning a strong ETag will be generated, unless the entity is 'fs.Stats', for which a weak ETag will be generated. A code example of setting an ETag for an HTTP response can be:
var etag = require('etag') // ... your application code here ... var body = 'Hello, world!' res.setHeader('ETag', etag(body))
Documentation for the etag package doesn't exist as separate documentation files or sites. Instead, all the necessary information, including the API reference and usage examples, are directly laid out in the readme file of the repository, which is accessible through its GitHub page here. For additional queries or clarifications, you can inspect the code directly or check the repository's issues for similar questions. Open-source platforms such as this support community contributions, which often include discussions and resolutions for common issues or confusions.
