- ⚙️ Works with Axios and Django Rest Framework
- 📝 Customizable
- 📚 Well documented (Docs)
Installation
npm install @singularit/drf-axios-middleware
Usage
Basic
@singularit/drf-axios-middleware
is a middleware for axios. It can be used with axios and django rest framework. It
introduces a new parameter filterSet
to the axios request config. This parameter is used to filter the request url.
The filterSet is a object with the following structure:
{
[field]: {
[operator]: value
}
}
By default, the operator can be one of the following:
const DefaultDRFFilters = ['in', 'exact', 'lt', 'gt', 'lte', 'gte', 'startswith', 'endswith']
You can use custom operators. See Customization for more information.
The final request url will be generated like: url?field__operator=value
.
Fields can be nested and will be generated like: url?field__nested__operator=value
.
See Nested Fields for more information.
Example
import axios from 'axios';
import applyDrfMiddleware from '@singularit/drf-axios-middleware';
const api = applyDrfMiddleware(axios.create());
// get all users with id >= 15
api.get('/api/v1/users/', {filterSet: {id: {gte: 15}}}).then((response) => {
console.log(response.data);
});
// request: GET /api/v1/users/?id__gte=15
Nested Fields
Nested fields can be used to filter nested objects. The middleware will generate the correct url for you.
Examples
Basic Nested Field
import axios from 'axios';
import applyDrfMiddleware from '@singularit/drf-axios-middleware';
const api = applyDrfMiddleware(axios.create());
// get all users with id >= 15
api.get('/api/v1/users/', {filterSet: {profile: {id: {gte: 15}}}}).then((response) => {
console.log(response.data);
});
// request: GET /api/v1/users/?profile__id__gte=15
Nested Field with multiple operators
import axios from 'axios';
import applyDrfMiddleware from '@singularit/drf-axios-middleware';
const api = applyDrfMiddleware(axios.create());
// get all users with id >= 15 and id <= 99
api.get('/api/v1/users/', {filterSet: {profile: {id: {gte: 15, lte: 99}}}}).then((response) => {
console.log(response.data);
});
// request: GET /api/v1/users/?profile__id__gte=15&profile__id__lte=99
Customization
The middleware can be customized by passing a config object to the applyDrfMiddleware
function.
Examples
Custom Filter Handler
import axios from 'axios';
import applyDrfMiddleware from '@singularit/drf-axios-middleware';
const api = applyDrfMiddleware(axios.create(), {
filterHanlder: {
notIn: (key, value) => {
return [{key: 'notin', value: value}]
}
}
});
// get all users with id not 1, 2 or 3
api.get('/api/v1/users/', {filterSet: {id: {notIn: [1, 2, 3]}}}).then((response) => {
console.log(response.data);
});
// request: GET /api/v1/users/?id__notin=1,2,3
// Note: depends on your array serializer
Note: notin
is not a valid operator for django rest framework. You have to implement the filter on your own.
Custom Filter to multiple Parameters (between to gte and lte)
import axios from 'axios';
import applyDrfMiddleware from '@singularit/drf-axios-middleware';
const api = applyDrfMiddleware(axios.create(), {
filterHanlder: {
between: (key, value) => {
return [
{key: 'gte', value: value[0]},
{key: 'lte', value: value[1]}
]
}
}
});
// get all users with id between 1 and 99
api.get('/api/v1/users/', {filterSet: {id: {between: [1, 99]}}}).then((response) => {
console.log(response.data);
});
// request: GET /api/v1/users/?id__gte=1&id__lte=99
