apax-react-core

Contains core react functionality developed by Apax Software LLC

Available functionality includes handling user account signup and login to DRF backends.

Usage

Connecting Locally

To connect to this repository locally, go to the root directory for apax-react-core:

yarn link

Then go to the project you want to connect (at the root level) and enter:

yarn link apax-react-core

To separate the projects again:

yarn unlink

inside apax-react-core level terminal.

Initialize Environment

This library requires a bit of configuration before it can be used. To do this, dispatch the following action early on in your application startup:

setEnv({app_evironment})

Example:

./redux/sagas.js

import { put } from 'react-saga/effects';
import { setEnv } from 'apax-react-core';

function* rootSaga () {
  ...

  yield put(setEnv({
    api_domain: process.env.REACT_APP_API_DOMAIN,
    api_root: process.env.REACT_APP_API_ROOT,
    token_name: process.env.REACT_APP_TOKEN_NAME,
  }));

  ...
}

./redux/index.js

...
import { envReducer as env } from 'apax-react-core';

...

export const rootReducer = combineReducers({
  env,
  ...
})

Environment Options

{
  // Domain name of backing server
  api_domain: 'localhost:8000',

  // Root URL of the api (do not include the '/api')
  api_root: 'http://localhost:8000',

  // Name to give the cookie when storing the user token
  token_name: 'react_core_app'
}

User Account

This library provides signup and login functionality for DRF backends. To use this functionality add the account sagas and reducers to you application:

./redux/index.js

import { accountReducer as account } from 'apax-react-core';

export const rootReducer = combineReducer({
  account,
  ...
});


./redux/sagas.js

import { accountSagas } from 'apax-react-core';

function* rootSaga () {
  ...
  yield call(accountSagas);
}

export default rootSaga;

Signup User

./pages/auth/Signup.js

import { useDispatch } from 'react-redux';
import { useHistory } from 'react-router-dom';
import { signup } from 'apax-react-core';

...

export default function Signup() {
  const history = useHistory();
  const dispatch = useDispatch();

  ...

  const onFormSubmit = (formData) => {
    dispatch(signup(formData, history));
  }
  ...
}

Login User

./pages/auth/Login.js

import { useDispatch } from 'react-redux';
import { useHistory } from 'react-router-dom';
import { login } from 'apax-react-core';

...

export default function Signup() {
  const history = useHistory();
  const dispatch = useDispatch();

  ...

  const onFormSubmit = (creds) => {
    dispatch(login(creds, history));
  }
  ...
}

Persistent Login

By default apax-react-core will store the users token as a cookie after login. However, there may be some cases where cookie storage is unavailable (such as React-Native environments) and so users logged in state will not persist between app loads.

This can be solved by storing the user token in the app (returned as key from LOGIN_SUCCESS or SIGNUP_SUCCESS) and then triggering a SET_USER_TOKEN action when the app first loads. This action will set the user token and trigger a call to LOAD_USER, effectively logging in the user.

Example

function* persistLogin() {
  const user = yield select(getUser);

  if (!user) {
    const token = yield AsyncStorage.getItem(USER_TOKEN_KEY);

    if (token) {
      yield put(setUserToken(token));
    } else {
      // Wait for login or signup and store the token in local storage
      const { key } = yield take([LOGIN_SUCCESS, SIGNUP_SUCCESS]);

      yield AsyncStorage.setItem(USER_TOKEN_KEY, key);
    }
  }
}

API

The following API methods are available:

apiGet(path, data|options)

apiPost(path, data|options)

apiPut(path, data|options)

apiPatch(path, data|options)

apiDelete(path, authenticationRequired = true)

Options

Default options for the apiGet, apiPost, apiPut, and apiPatch methods can be overridden using the format below (all fields are optional):

Note: When overriding options, request data must be passed along inside of options.

{
  /*
    Request data

    default: null
  */
  data: object,

  /*
    Extra headers to include with the request (key/value pairs)

    default: undefined
  */
  headers: object,

  /*
   Should request include authentication headers

   default: true
  */
  authenticationRequired: boolean,
}

Usage

import {
apiGet
} from 'apax-react-core';

...

const response = yield apiGet('api/mypath/');
