An enhanced HTTP client based on fetch.
Blogpost: fetch-it an enhanced http client based on fetch
Features
You can do all the same thing that you do with fetch, plus:
- Add middleware, to intercept requests and responses
- Create custom config instances
Installation
using npm:
$ npm install --save fetch-it
Examples
GET request
fetchIt.get('http://httpbin.org/get?param1=param1') .then((response) => response.json()) .then((json) => console.log(json)) .catch((error) => console.error(error));
POST request
fetchIt.post('http://httpbin.org/post?param1=param1', { param2: 'param2', param3: 'param3' }).then((response) => response.json()) .then((json) => console.log(json)) .catch((error) => console.error(error));
API
Request methods
fetchIt.fetch(url[, options])
fetchIt.fetch(request)
You can perform requests the same way as you do with fetch().
fetchIt.fetch(url, { method: 'POST', body: JSON.stringify(data), headers: { 'Content-Type': 'application/json' } }).then((response) => { // handle response }).catch((error) => { // handle error });
And we provide some convenience aliases for the supported methods.
fetchIt.get(url[, options])
fetchIt.get(request)
fetchIt.post(url[, data[, options]])
fetchIt.post(request)
fetchIt.put(url[, data[, options]])
fetchIt.put(request)
fetchIt.patch(url[, data[, options]])
fetchIt.patch(request)
fetchIt.delete(url[, options])
fetchIt.delete(request)
fetchIt.head(url[, options])
fetchIt.head(request)
Creating custom config instances
You can create a custom config instance of fetchIt
fetchIt.create([options])
let apiFetch = fetchIt.create({ headers: { 'Authorization': 'Bearer ' + getAPIToken(), 'X-My-Custom-Header': 'CustomHeader' } }); apiFetch.get(url).then((response) => { // handle response }).catch((error) => { // handle error });
Middleware
You can add middleware objects to any instance, to intercept requests and responses.
The middleware object must have defined at least one of these methods:
- request(request) , to intercept a request,
- requestError(error) , to intercept an error from a previous middleware,
- response(response) , to intercept a response,
- responseError(error) , to intercept an error from a previous middleware.
let jsonMiddleware = { response(res) { return res.json().catch((e) => { return e; }); } };
fetchIt.addMiddlewares(ArrayOfMiddlewares)
fetchIt.addMiddlewares([jsonMiddleware]);
fetchIt.clearMiddlewares()
Roadmap
- Better docs
- Add more middlewares
- Add better tests
- Add travis and coveralls
- Create another project to create something similar to $resource based on fetch-it.
