[![Known Vulnerabilities](https://snyk.io/test/npm/promise-core/badge.svg?style=flat-square&maxAge=2592000)](https://snyk.io/test/npm/promise-core)
This package is the core for the following packages:
- [`request-promise`](https://github.com/request/request-promise)
- [`request-promise-any`](https://github.com/request/request-promise-any)
- [`request-promise-bluebird`](https://github.com/request/request-promise-bluebird)
- [`request-promise-native`](https://github.com/request/request-promise-native)
`request-promise-core` contains the core logic to add Promise support to [`request`](https://github.com/request/request).
Please use one of the libraries above. It is only recommended to use this library directly, if you have very specific requirements.
## Installation for `request@^2.34`
This module is installed via npm:
```
npm install --save request
npm install --save request-promise-core
```
`request` is defined as a peer-dependency and thus has to be installed separately.
## Usage for `request@^2.34`
``` js
// 1. Load the request library
// Only use a direct require if you are 100% sure that:
// - Your project does not use request directly. That is without the Promise capabilities by calling require('request').
// - Any of the installed libraries use request.
// ...because Request's prototype will be patched in step 2.
/* var request = require('request'); */
// Instead use:
var stealthyRequire = require('stealthy-require');
var request = stealthyRequire(require.cache, function () {
return require('request');
});
// 2. Add Promise support to request
var configure = require('request-promise-core/configure/request2');
configure({
request: request,
// Pass your favorite ES6-compatible promise implementation
PromiseImpl: Promise,
// Expose all methods of the promise instance you want to call on the request(...) call
expose: [
'then', // Allows to use request(...).then(...)
'catch', // Allows to use request(...).catch(...)
'promise' // Allows to use request(...).promise() which returns the promise instance
],
// Optional: Pass a callback that is called within the Promise constructor
constructorMixin: function (resolve, reject) {
// `this` is the request object
// Additional arguments may be passed depending on the PromiseImpl used
}
});
// 3. Use request with its promise capabilities
// E.g. crawl a web page:
request('http://www.google.com')
.then(function (htmlString) {
// Process html...
})
.catch(function (err) {
// Crawling failed...
});
```
## Installation and Usage for `request@next`
[Request Next](https://github.com/request/request/issues/1982) is still in alpha. However, `request-promise-core` is already designed to be compatible and ships with a configuration helper `require('request-promise-core/configure/request-next')` that is [used by `request-promise`](https://github.com/request/request-promise/blob/next/lib/rp.js) in its "next" branch.
## Contributing
To set up your development environment:
1. clone the repo to your desktop,
2. in the shell `cd` to the main folder,
3. hit `npm install`,
4. hit `npm install gulp -g` if you haven't installed gulp globally yet, and
5. run `gulp dev`. (Or run `node ./node_modules/.bin/gulp dev` if you don't want to install gulp globally.)
`gulp dev` watches all source files and if you save some changes it will lint the code and execute all tests. The test coverage report can be viewed from `./coverage/lcov-report/index.html`.
If you want to debug a test you should use `gulp test-without-coverage` to run all tests without obscuring the code by the test coverage instrumentation.
## Change History
- 1.1.2 (2019-02-14)
- Security fix: bumped `lodash` to `^4.17.11`. See [vulnerabilty reports](https://snyk.io/vuln/search?q=lodash&type=npm).
*(Thanks to @lucaswillering and @sam-warren-finnair for reporting this in issues [#12](https://github.com/request/promise-core/issues/12) and [#13](https://github.com/request/promise-core/issues/13) and thanks to @Alec321 for pull request [#14](https://github.com/request/promise-core/pull/14).)*

- 1.1.0 (2016-07-30)
- Added `constructorMixin` option to enable [request/request-promise#123](https://github.com/request/request-promise/pull/123)
