JS-Lib

Http

App Masters fetch class.

Configuration

On the project setup, set the base url for your API and the necessary headers:

import { Http } from '@app-masters/js-lib';

...

const version = '1.0.0'; // get from package.json
const client = 'mobile'; // use 'mobile', 'admin' or 'web'
const contentType = 'application/json';
const baseURL = 'http://localhost.com:3000';
const token = 'JWT-0000000000000'; // user's authentication token

Http.setup(version, client, contentType);
Http.setBaseURL(baseURL);

// after the authentication process
Http.setAuthorization(token);

Setting your headers like this, will give you this headers:

{
    'content-type': 'application/json',
    'mobile-version': '1.0.0',
    'client': 'mobile',
    'authorization': 'JWT-0000000000000'
}

Also, you can set a endpoint param. This param is a key/value that will overwrite the key with the value every time that it's found in a fetch call.

Examples:

Http.setEndpointParam('{_userID}', user.id);
Http.setEndpointParam('{_maxItems}', 5);

...

Http.get('/{_userID)');
Http.get('/items/?quantity={_maxItems}');

Anytime you can reset the headers to the default setup using Http.reset(). This will reset your headers to what was set in Http.setup(), removing the authorization and all endpoint parameters.

Usage

The Http class have 4 main asynchronous methods for fetch: GET, POST, PUT and DELETE. After you set the base URL, you only need to pass the endpoint to fetch it.

Examples:

Http.get('/users').then(response => {
    console.log(response);
}).catch(error => {
    console.error(error);
});

// Using endpoint params
Http.get('/users/{_userID}').then(response => {
    console.log(response);
}).catch(error => {
    console.error(error);
});

Http.post('/users', {email: '[e-mail]'}).then(response => {
    console.log(response);
}).catch(error => {
    console.error(error);
});

// Full URLs ignore the baseURL set.
Http.post('http://localhost.com:3001/otherUsers', {email: '[e-mail]'}).then(response => {
    console.log(response);
}).catch(error => {
    console.error(error);
});

Http.put('/users/TH1S154U53R1D', {email: '[e-mail]'}).then(response => {
    console.log(response);
}).catch(error => {
    console.error(error);
});

Http.delete('/users/TH1S154U53R1D').then(response => {
    console.log(response);
}).catch(error => {
    console.error(error);
});

The status codes considered as success are: 200, 201 and 204 (on delete).

AppBoostrap

App Masters default app setup process.

Create a config file with defaults environments:

const envs = {};

envs.development = {
    baseUrl: "http://localhost:3000/api",
    uploadCareToken: "someXPTOtoken",
    rollbarToken: "anotherCrazyToken"
};

envs.development_firebase = {
    baseUrl: "https://remotehost-dev.herokuapp.com:3000/api",
    uploadCareToken: "someXPTOtoken",
    rollbarToken: "anotherCrazyToken"
};

envs.staging = {
    baseUrl: "https://remotehost-staging.herokuapp.com:3000/api",
    uploadCareToken: "someXPTOtoken",
    rollbarToken: "anotherCrazyToken"
};

envs.production = {
    baseUrl: "https://remotehost-prod.herokuapp.com:3000/api",
    uploadCareToken: "someXPTOtoken",
    rollbarToken: "anotherCrazyToken"
};

export default envs;

Import and call AppBootstrap:

import {store, storage} from './store';
import packag from '../package.json';
import envs from './config';
import {AppBootstrap} from '@app-masters/js-lib';

class App extends Component {
    constructor () {
        super();
        try {
            let callbacks = {
                onMinVersionNotSatifies: (version) => {
                    alert("Você deve atualizar sua versão agora! Por favor recarregue a página, se a mensagem continuar, limpe o cache do navegador.");
                },
                onNewVersion: (version) => {
                    alert('Bem vindo à nova versão!');
                    if (version === '0.2.0') {
                      // Some new version decision
                    }
                },
                onUncaughtError: (e) => {
                    if (e.message !== 'Failed to fetch') {
                        Rollbar.error(e);
                        alert("Houve um erro inesperado e os programadores responsáveis já foram avisados. \n\n Detalhes técnicos: " + e.message);
                    } else {
                        alert('Falha na conexāo');
                    }
                }
            };

            // Bootstrap
            AppBootstrap.setup("web", packag, envs, storage, callbacks);
        } catch (e) {
            alert("Houve um erro inesperado e os programadores responsáveis já foram avisados. \n\n Detalhes técnicos: " + e.message);
        }
    }
}

(callbacks are the same object used with AMActions.setup()).
