AxiosDataSource for Apollo

A rest datasource that uses axios under the hood. This allows adding generic interceptors, adapters etc. Integrates with cache and cache policies. Supports Interceptors.

Using

yarn add @ovotech/apollo-datasource-axios

import { AxiosDataSource } from '@ovotech/apollo-datasource-axios';

interface User {
  name: string;
}

export class MyDataSource extends AxiosDataSource {
  users(id: string) {
    return this.get<User>(`/users/${id}`);
  }
}

const dataSource = new MyDataSource({ baseURL: '...' });

Interceptors

You can pass interceptors to axios declaratively with the interceptros property.

import { Interceptor } from '@ovotech/apollo-datasource-axios';
const logger: Interceptor = {
  response: {
    onFulfilled: res => {
      console.log(res);
      return res;
    },
    onRejected: err => {
      console.log(err);
      return err;
    },
  },
};

const dataSource = new MyDataSource({ baseURL: '...', interceptors: [logger] });

Advanced types

If you want to be more exact on the types passed to and from axios, you can fill in the optional types. This is useful if some of your interceptors are adding properties to the config.

import { AxiosDataSource, AxiosDataSourceConfig } from '@ovotech/apollo-datasource-axios';

interface Context extends AxiosDataSourceConfig {
  version: string;
}

export class MyDataSource extends AxiosDataSource<Context> {
  users(id: string) {
    return this.get(`/users/${id}`, { version: '123' });
  }
}

Running the tests

You can run the tests with:

yarn test

Coding style (linting, etc) tests

Style is maintained with prettier and tslint

yarn lint

Deployment

Deployment is preferment by lerna automatically on merge / push to master, but you'll need to bump the package version numbers yourself. Only updated packages with newer versions will be pushed to the npm registry.
