Anyway, pre-commit hook is checking lint with our internal installed eslint version. So if your IDE is not showing you the errors, but you have them in pre-commit hook, re-check IDE :D
Add plugin linter-eslint. Go to the plugin’s configuration and enable option Fix errors on save
Stylelint is using to control the codestyle in style files. Configure your IDE to use config from this repo.

Workflow:
We are not following some strict rule on this stage of branch naming. So we have a single rule for the branch names:
Bad example
fix-1
redesign
Good example
fix-signals-table
new-user-profile-page
If you are using JIRA as a task manager, follow this naming convention
[type of ticket]/[number of branch]-[short-title]
feature/FRB-123-change-titles
fix/FRB-431-retina-images
We are creating React application with component-approach. This means, what we try to decompose our UI into re-usable parts.
Try to make components PURE when it’s possible. Avoid using redux or inner state for components in app/common/components
.
Base component contains next files:
index.js
- base componentstyles.scss
- styles fileindex.story.js
- storybook fileSee the example component.
Use recompose to create logic layout of your components. recompose allow us to split logic into multiple re-usable parts.
Storybook is using as a UI library. We are using it as documentation for our UI. The goals are:
The rule is: write a story for all generic pure components and blocks and show all the existing variations.
Help your teammates understand from story how to use your component. Not just write the story of itself. Think about your colleagues.
Shortly about our styles:
We’re using scoped styles, so you don’t need to use BEM or other methodology to avoid conflicts in the styles. In BEM terminology, you don’t have to use elements. Use only block and modificators.
If you feel that you also need an element - think, probably you have to extract a new component from this template.
Bad example
.page {
&__title {}
&__content {
&_active {}
}
}
Good example
.root {} // root element
.title {}
.content {
&.isActive {}
}
Use is
prefix for the modificators.
We are using isomorphic style loader
to calculate critical CSS path. Use withStyles HOC to connect component and style. Use withStyles
alias for import.
For example
import React from 'react';
import PropTypes from 'prop-types';
import withStyles from 'withStyles';
import { compose } from 'recompose';
import styles from './styles.scss';
const Poster = ({ src, title }) => (
<div className={styles.root} style={{ backgroundImage: `url(${src})` }} alt={title} />
);
Poster.propTypes = {
children: PropTypes.node,
};
export default compose(
withStyles(styles)
)(Poster);
Make names meaningful.
<Button d />
Good example
<Button disabled />
Make property for group of variants, not only of one specific case
Bad example
<Button red />
<Button blue />
<Button green />
Good example
<Button color="red" />
<Button color="blue" />
<Button color="green" />
Make property short
Bad example
<Button withLongValue />
Good example
<Button long />
Use on
prefix for callbacks
Bad example
<Component change={someCallback} />
Good example
<Component onChange={someCallback} />
true
if present
<Component black />
equals <Component black={ true } />
false
if missed
<Component />
equals <Component black={ false } />
Use component fully as a block. Don’t make the components styles configurable outside. It has to have the deterministic number of possible variants.
Bad example
<Component className="newClassname" />
This is a chore. Passing classname or style from parent component can solve a problem easily in short terms, but in the future, you will be updating your components and you will not remember about this modification. so you will not test it. and it would be a bug.
Good example
<div className={styles.wrapper}>
<Component disabled />
</div>
We are using redux as our global state manager in the app. Our base store structure is:
data
- data redux modules.form
- connect redux-formrouting
- connect react-router-reduxui
- reducers of UI componentsActions and reducers are stored in the same file. We are using redux-actions
as a single way to create an action. See example.
Selectors are stored in redux/index.js file. Basic set of data selectors contains next methods:
export const getMovie = (state, id) => denormalize(id, schemas.movie, state.data);
export const getMovies = (state, ids) => ids.map(id => getMovie(state, id));
export const getAllMovies = state => getMovies(state, Object.keys(state.data.movies));
We are using redux-api-middleware to make the API calls. It’s use universal fetch internally.
Use method invoke
to create API request actions.
We use redux as a caching layer. Redux store contains data object, that has next structure
example
data: {
movies: {
1: {
id: 1,
name: 'The Shawshank Redemption'
},
2: {
id: 2,
name: 'The Godfather'
},
},
directors: {
1: {
id: 1,
name: 'Francis Ford Coppola'
}
}
}
So all the data entities are grouped by collection and is stored in map, there key is id
of the entity and value
is entity itself.
This structure allows us to easily find entity in store by id.
Each API request contains normalization of the response. Example.
To normalize data we are using normalizr
package. Normalization schemas are store in schemas
folder.
See an example of fetching and normalization of the data here.
Use connect
and selectors
to get the store data on the page. Don’t store the data directly on the page. Store identifier and get the value by id, with selector instead.
For example,
export default compose(
withStyles(styles),
translate(),
withRouter,
provideHooks({
fetch: ({ dispatch, params, setProps }) => dispatch(fetchMovie(params.id)).then((response) => {
setProps({
movieId: response.payload.result,
});
}),
}),
connect((state, ownProps) => ({
movie: getMovie(state, ownProps.movieId),
})),
)(MoviesDetailsPage);
After the fetch of the data we don’t store the whole object, but just the id of the movie and then we get whole object with getMovie selector. It allow us to be sure, that redux store is only one source of data in our applications. It helps to avoid many bugs.
Page URL: /users
API request: get:/users
Page URL: /users/:id
API request: get:/users/:id
Page URL: /users/new
API request: post:/users
e.g /users?page=1, /users?q=John Doe
Pages and layouts are 2 places, there data can be fetched. WE don’t fetch the data into blocks. Only in the containers, that are used as a component in Routes, so they are URL driven.
To fetch the data on the page we are using redial + react-router-redial
hook | beforeTransition | afterTransition | client | server |
---|---|---|---|---|
fetch |
+ | - | + | + |
defer |
- | + | + | - |
server |
- | + | - | + |
done |
- | + | + | + |
We’re additional passing dispatch
and getState
methods to the hooks, so you can access the store and dispatch an action.
TODO
Cypress.io is used for E2E testing.
To run test, execute next command. You need server started and installed Chrome browser on your machine.
yarn test:acceptance
Tests are storing in cypress folder.
TODO. add jest to boilerplate
TODO. add argos CI to boilerplate
We are using gettext
standard for our basic localization process.
yarn locales:extract
This command will extract string for localization into locales/source.pot
file.
Use Poedit to create lang files based on .pot file.
Localization is configured in common/services/i18next.js
. Check the code to see how to import .po
file with new language to the app.
We are using Redux-form as a single way to work with the forms.
We use per-form validation. For validation we are using react-nebo15-validate
To add custom validation message, add it to ErrorMessages components. This component is used in Field components to show validation messages.
See the existing customization. Use this common in all places, when you need to display the error message based on error object.
Configuration of the 3rd party services is stored in common/services
. See the example of i18next and validations configurations. They are separately connected to client and server entrypoints.

Are you leading an organization that has a large campus, e.g., a large university? You are probably thinking of introducing an electric scooter/bicycle fleet on the campus, and why wouldn’t you?
Introducing micro-mobility in your campus with the help of such a fleet would help the people on the campus significantly. People would save money since they don’t need to use a car for a short distance. Your campus will see a drastic reduction in congestion, moreover, its carbon footprint will reduce.
Micro-mobility is relatively new though and you would need help. You would need to select an appropriate fleet of vehicles. The people on your campus would need to find electric scooters or electric bikes for commuting, and you need to provide a solution for this.
To be more specific, you need a short-term electric bike rental app. With such an app, you will be able to easily offer micro-mobility to the people on the campus. We at Devathon have built Autorent exactly for this.
What does Autorent do and how can it help you? How does it enable you to introduce micro-mobility on your campus? We explain these in this article, however, we will touch upon a few basics first.
You are probably thinking about micro-mobility relatively recently, aren’t you? A few relevant insights about it could help you to better appreciate its importance.
Micro-mobility is a new trend in transportation, and it uses vehicles that are considerably smaller than cars. Electric scooters (e-scooters) and electric bikes (e-bikes) are the most popular forms of micro-mobility, however, there are also e-unicycles and e-skateboards.
You might have already seen e-scooters, which are kick scooters that come with a motor. Thanks to its motor, an e-scooter can achieve a speed of up to 20 km/h. On the other hand, e-bikes are popular in China and Japan, and they come with a motor, and you can reach a speed of 40 km/h.
You obviously can’t use these vehicles for very long commutes, however, what if you need to travel a short distance? Even if you have a reasonable public transport facility in the city, it might not cover the route you need to take. Take the example of a large university campus. Such a campus is often at a considerable distance from the central business district of the city where it’s located. While public transport facilities may serve the central business district, they wouldn’t serve this large campus. Currently, many people drive their cars even for short distances.
As you know, that brings its own set of challenges. Vehicular traffic adds significantly to pollution, moreover, finding a parking spot can be hard in crowded urban districts.
Well, you can reduce your carbon footprint if you use an electric car. However, electric cars are still new, and many countries are still building the necessary infrastructure for them. Your large campus might not have the necessary infrastructure for them either. Presently, electric cars don’t represent a viable option in most geographies.
As a result, you need to buy and maintain a car even if your commute is short. In addition to dealing with parking problems, you need to spend significantly on your car.
All of these factors have combined to make people sit up and think seriously about cars. Many people are now seriously considering whether a car is really the best option even if they have to commute only a short distance.
This is where micro-mobility enters the picture. When you commute a short distance regularly, e-scooters or e-bikes are viable options. You limit your carbon footprints and you cut costs!
Businesses have seen this shift in thinking, and e-scooter companies like Lime and Bird have entered this field in a big way. They let you rent e-scooters by the minute. On the other hand, start-ups like Jump and Lyft have entered the e-bike market.
Think of your campus now! The people there might need to travel short distances within the campus, and e-scooters can really help them.
What advantages can you get from micro-mobility? Let’s take a deeper look into this question.
Micro-mobility can offer several advantages to the people on your campus, e.g.:

The electric scooter revolution has caught on super-fast taking many cities across the globe by storm. eScooters, a renovated version of old-school scooters now turned into electric vehicles are an environmentally friendly solution to current on-demand commute problems. They work on engines, like cars, enabling short traveling distances without hassle. The result is that these groundbreaking electric machines can now provide faster transport for less — cheaper than Uber and faster than Metro.
Since they are durable, fast, easy to operate and maintain, and are more convenient to park compared to four-wheelers, the eScooters trend has and continues to spike interest as a promising growth area. Several companies and universities are increasingly setting up shop to provide eScooter services realizing a would-be profitable business model and a ready customer base that is university students or residents in need of faster and cheap travel going about their business in school, town, and other surrounding areas.
In many countries including the U.S., Canada, Mexico, U.K., Germany, France, China, Japan, India, Brazil and Mexico and more, a growing number of eScooter users both locals and tourists can now be seen effortlessly passing lines of drivers stuck in the endless and unmoving traffic.
A recent report by McKinsey revealed that the E-Scooter industry will be worth― $200 billion to $300 billion in the United States, $100 billion to $150 billion in Europe, and $30 billion to $50 billion in China in 2030. The e-Scooter revenue model will also spike and is projected to rise by more than 20% amounting to approximately $5 billion.
And, with a necessity to move people away from high carbon prints, traffic and congestion issues brought about by car-centric transport systems in cities, more and more city planners are developing more bike/scooter lanes and adopting zero-emission plans. This is the force behind the booming electric scooter market and the numbers will only go higher and higher.
Companies that have taken advantage of the growing eScooter trend develop an appthat allows them to provide efficient eScooter services. Such an app enables them to be able to locate bike pick-up and drop points through fully integrated google maps.
It’s clear that e scooters will increasingly become more common and the e-scooter business model will continue to grab the attention of manufacturers, investors, entrepreneurs. All this should go ahead with a quest to know what are some of the best electric bikes in the market especially for anyone who would want to get started in the electric bikes/scooters rental business.
We have done a comprehensive list of the best electric bikes! Each bike has been reviewed in depth and includes a full list of specs and a photo.

With more of us using smartphones, the popularity of mobile applications has exploded. In the digital era, the number of people looking for products and services online is growing rapidly. Smartphone owners look for mobile applications that give them quick access to companies’ products and services. As a result, mobile apps provide customers with a lot of benefits in just one device.
Likewise, companies use mobile apps to increase customer loyalty and improve their services. Mobile Developers are in high demand as companies use apps not only to create brand awareness but also to gather information. For that reason, mobile apps are used as tools to collect valuable data from customers to help companies improve their offer.
There are many types of mobile applications, each with its own advantages. For example, native apps perform better, while web apps don’t need to be customized for the platform or operating system (OS). Likewise, hybrid apps provide users with comfortable user experience. However, you may be wondering how long it takes to develop an app.
To give you an idea of how long the app development process takes, here’s a short guide.
_Average time spent: two to five weeks _
This is the initial stage and a crucial step in setting the project in the right direction. In this stage, you brainstorm ideas and select the best one. Apart from that, you’ll need to do some research to see if your idea is viable. Remember that coming up with an idea is easy; the hard part is to make it a reality.
All your ideas may seem viable, but you still have to run some tests to keep it as real as possible. For that reason, when Web Developers are building a web app, they analyze the available ideas to see which one is the best match for the targeted audience.
Targeting the right audience is crucial when you are developing an app. It saves time when shaping the app in the right direction as you have a clear set of objectives. Likewise, analyzing how the app affects the market is essential. During the research process, App Developers must gather information about potential competitors and threats. This helps the app owners develop strategies to tackle difficulties that come up after the launch.
The research process can take several weeks, but it determines how successful your app can be. For that reason, you must take your time to know all the weaknesses and strengths of the competitors, possible app strategies, and targeted audience.
The outcomes of this stage are app prototypes and the minimum feasible product.

Yucca/PrerenderBundle
Backbone, EmberJS, Angular and so more are your daily basis ? In case of an admin area, that's fine, but on your front office, you might encounter some SEO problems
Thanks to Prerender.io, you now can dynamically render your JavaScript pages in your server using PhantomJS.
This bundle is largely inspired by bakura10 work on zfr-prerender
Install the module by typing (or add it to your composer.json
file):
$ php composer.phar require "yucca/prerender-bundle" "0.1.*@dev"
Register the bundle in app/AppKernel.php
:
// app/AppKernel.php
public function registerBundles()
{
return array(
// ...
new Yucca\PrerenderBundle\YuccaPrerenderBundle(),
);
}
Enable the bundle's configuration in app/config/config.yml
:
# app/config/config.yml
yucca_prerender: ~
GET
request to the prerender service (PhantomJS server) for the page's prerendered HTMLThis bundle comes with a sane default, extracted from prerender-node middleware, but you can easily customize it:
#app/config/config.yml
yucca_prerender:
....
By default, YuccaPrerenderBundle uses the Prerender.io service deployed at http://prerender.herokuapp.com
. However, you may want to deploy it on your own server. To that extent, you can customize YuccaPrerenderBundle to use your server using the following configuration:
#app/config/config.yml
yucca_prerender:
backend_url: http://localhost:3000
With this config, here is how YuccaPrerender will proxy the "https://google.com" request:
GET
http://localhost:3000/https://google.com
YuccaPrerender decides to pre-render based on the User-Agent string to check if a request comes from a bot or not. By default, those user agents are registered: 'baiduspider', 'facebookexternalhit', 'twitterbot'. Googlebot, Yahoo, and Bingbot should not be in this list because we support escaped_fragment instead of checking user agent for those crawlers. Your site must have to understand the '#!' ajax url notation.
You can add other User-Agent string to evaluate using this sample configuration:
#app/config/config.yml
yucca_prerender:
crawler_user_agents: ['yandex', 'msnbot']
YuccaPrerender is configured by default to ignore all the requests for resources with those extensions: .js
, .css
, .less
, .png
, .jpg
, .jpeg
, .gif
, .pdf
, .doc
, .txt
, .zip
, .mp3
, .rar
, .exe
, .wmv
, .doc
, .avi
, .ppt
, .mpg
, .mpeg
, .tif
, .wav
, .mov
, .psd
, .ai
, .xls
, .mp4
, .m4a
, .swf
, .dat
, .dmg
, .iso
, .flv
, .m4v
, .torrent
. Those are never pre-rendered.
You can add your own extensions using this sample configuration:
#app/config/config.yml
yucca_prerender:
ignored_extensions: ['.less', '.pdf']
Whitelist a single url path or multiple url paths. Compares using regex, so be specific when possible. If a whitelist is supplied, only url's containing a whitelist path will be prerendered.
Here is a sample configuration that only pre-render URLs that contains "/users/":
#app/config/config.yml
yucca_prerender:
whitelist_urls: ['/users/*']
Note: remember to specify URL here and not Symfony2 route names.
Blacklist a single url path or multiple url paths. Compares using regex, so be specific when possible. If a blacklist is supplied, all url's will be pre-rendered except ones containing a blacklist part. Please note that if the referer is part of the blacklist, it won't be pre-rendered too.
Here is a sample configuration that prerender all URLs excepting the ones that contains "/users/":
#app/config/config.yml
yucca_prerender:
blacklist_urls: ['/users/*']
Note: remember to specify URL here and not Symfony22 route names.
If you want to make sure your pages are rendering correctly:
Thanks
