# axios // adapters
The modules under `adapters/` are modules that handle dispatching a request and settling a returned `Promise` once a response is received.
## Example
```js
var settle = require('../core/settle');
module.exports = function myAdapter(config) {
// At this point:
// - config has been merged with defaults
// - request transformers have already run
// - request interceptors have already run
// Make the request using config provided
// Upon response settle the Promise
return new Promise(function (resolve, reject) {
var response = {
data: responseData,
status: request.status,
statusText: request.statusText,
headers: responseHeaders,
config: config,
request: request,
};
settle(resolve, reject, response);
// From here:
// - response transformers will run
// - response interceptors will run
});
};
```

# axios // core
The modules found in `core/` should be modules that are specific to the domain logic of axios. These modules would most likely not make sense to be consumed outside of the axios module, as their logic is too specific. Some examples of core modules are:
- Dispatching requests
- Requests sent via `adapters/` (see lib/adapters/README.md)
- Managing interceptors
- Handling config

# axios // helpers
The modules found in `helpers/` should be generic modules that are _not_ specific to the domain logic of axios. These modules could theoretically be published to npm on their own and consumed by other modules or apps. Some examples of generic modules are things like:
- Browser polyfills
- Managing cookies
- Parsing HTTP headers
