Installation

npm i --save @commite/ajax-client rxjs

Dependencies

"rxjs": "^6.3.3"

API

Ajax client uses rxjs/ajax API to perform calls and returns rxjs/observable.

All request accepts an Ajax request options, post, put and patch requests body param can also be typed, other way any type will be assumed.

All request returns an Ajax response, response param can also be typed, other way any type will be assumed.

Config

A base url can be setted using library constructor.

const ajaxClient = new AjaxClient({
  baseUrl: 'my-base-url.com'
});

Equivalent to adding an interceptor like:

interceptors.request.push(request => ({
  ...request,
  url: `${baseUrl}${request.url}`
}));

Get/Delete

[get|delete]<T>(url: string, options?: Partial<AjaxClientRequest<null>>): Observable<AjaxClientResponse<T>>

Get example

const ajaxClient = new AjaxClient();

ajaxClient.get<GetUsersResponse>('/users', { headers: ... }).subscribe((userRes) => {
  [...]
});

Post/Put/Patch

[post|put|patch]<T, Y>(url: string, body: Y, options?: Partial<AjaxClientRequest<Y>): Observable<AjaxClientResponse<T>>

Post example

const ajaxClient = new AjaxClient();

ajaxClient.post<PostUserResponse, PostUserBody>('/users', { email: 'test@test.com'}, { headers: ... }).subscribe((userRes) => {
  [...]
});

Back to top

Request

request<T, Y>(options: Partial<AjaxClientRequest<Y>>): Observable<AjaxClientResponse<T>>

ajaxClient.request<RequestResponse, RequestBody>({
  method: 'POST',
  body: {...},
  headers: {...}
}).subscribe((reqRes) => {
  [...]
})

Interceptors

Request and response could be intercepted.

Request interceptor

A request interceptor is a function that accepts a Partial<AjaxClientRequest<any>> object and returns a modified (or not) Partial<AjaxClientRequest<any>>.

RequestInterceptor = (
  options: Partial<AjaxRequest<any>>
) => Partial<AjaxRequest<any>>

Request interceptors can be managed through ajaxClient.interceptors.request array.

ajaxClient.interceptors.request.push(options => {
  return {
    ...options,
    url: `https://my-base-url.com/${options.url}`
  };
});

Response interceptor

A response interceptor is a function that accepts a AjaxClientResponse<any> object and returns a modified (or not) AjaxClientResponse<any>.

ResponseInterceptor = (response: AjaxClientResponse<any>) => AjaxClientResponse<any>;

Response interceptors can be managed through ajaxClient.interceptors.response array.

ajaxClient.interceptors.response.push(ajaxResponse => {
  return {
    ...ajaxResponse,
    response: ajaxResponse.response.split(',')
  };
});
