Generic helper class for wrapping axios calls

##### config [optional]
The configuration of an axios instance.
##### collector [optional]
The configuration of requests collector is an object:
`json`
{
"collectErrors": 10,
"collectRequests": 10
}
, head, put, post, delete.Methods
get and head have the signature (url, params, options); put, post, while the delete method
has (url, data, params, options) signature.The
params argument stands for query string parameters while options is a request settings.Currently 4 request settings are supported:
-
concurrentId (string): optional request id
- collectRequest (bool): optional flag, telling if the request should be logger (default true)
- requestConfig (object): optional config with the custom request parameters
- headers (object): optional object with custom request headers.
- timeout (number): optional request timeout
- onDownloadProgress (function): optional callback for processing file download progress$3
The setDefaultHeader({name (string), value (string), methods (array)}) method allows to add a default
request header.Arguments
name and value are required, optional argument methods specified all methods which get those
default headers (by default all methods will get those headers).$3
The setCSRFToken method allows specifying CSRF-token, which will be added to all put, post and delete
requests.$3
Sometimes it is better to cancel the request in flight if its results are no longer needed. To make this
happen, one should pass to request's options the concurrentId id. When the next request with the same
concurrentId occurs the previous request with that id will be cancelled.One cancel a request manually as well by invoking the
cancelRequest(concurrentId) method.$3
It is possible to set up requests collection into the local storage using the collector option. It stores
all requests and errors separately. The following apiInstance will keep 10 last requests (both successful
and not) and 10 last erroneous requests.
`javascript
const apiInstance = new API({
collector: {
collectErrors: 10,
collectRequests: 10
}
});
`To obtain saved requests one have to invoke the
getCollectedRequests method which returns the object
{errors: [...], requests: [...]}.$3
The suggested usage is to subclass the base AxiosWrapper class:
`javascript
export class API extends AxiosWrapper {
getProjects() {
return this.get('/projects');
}
getSensors({project, selectors}) {
return this.get(/projects/${project}/sensors, {selectors, pageSize: 200});
}
getNames({project, selectors}) {
return this.get(/projects/${project}/sensors/names, {selectors});
}
getLabels({project, names, selectors}) {
return this.get(/projects/${project}/sensors/labels, {names, selectors});
}
}
`When the
baseURL parameter is passed into axios config, all requested pathnames will be appended to it.
`javascript
const apiInstance = new API({
config: {
baseURL: '/api/v2'
}
});
