Web

OneFx is a full-stack framework for building web apps. Here are the features you’ll find in Onefx.js:

Server-side rendering and universal rendering with React and Redux
Apollo GraphQL (docs + playground), ES2017, TypeScript, TSX support out of the box
Server-side development via Koa.js

Create a project

git clone https://github.com/puncsky/web-onefx-boilerplate.git my-awesome-project

Run your project

This is intended for *nix users. If you use Windows, go to Run on Windows. Let’s first prepare the environment.

cd my-awesome-project

nvm use 10.15.0
npm install

# prepare environment variable
cp ./.env.tmpl ./.env

Development mode

To run your project in development mode, run:

npm run watch

The development site will be available at http://localhost:5000.

Production Mode

It’s sometimes useful to run a project in production mode, for example, to check bundle size or to debug a production-only issue. To run your project in production mode locally, run:

npm run build-production
NODE_ENV=production npm run start

NPM scripts

npm run test: test the whole project and generate a test coverage
npm run ava ./path/to/test-file.js: run a specific test file
npm run build: build source code from src to dist
npm run lint: run the linter
npm run flow: run the flow type check
npm run kill: kill the node server occupying the port 4100.

Code Styles

We use prettier, tslint, and editorconfig to enforce consistent styles across the whole project, so that we will not bikeshed on coding styles in the code review.

However, please visit our Contributing Code before submitting your code.

Guides

State management

We use redux to manage state in onefx.js. To pass the state from the server to the initial page during the server-side rendering, in the server use ctx.setState(path, val) to set the state:

server.get('SPA', '/*', function onRoute(ctx) {
 ctx.setState('base.sampleState', 'this is a sample initial state');
 ctx.body = ctx.isoReactRender({
 VDom: (
 <AppContainer/>
 ),
 reducer: noopReducer,
 clientScript: '/main.js',
 });
});

And use the state in the react component:

const SampleStateContainer = connect(
 state => ({text: state.base.sampleState})
)(function SampleState({text}) {
 return (
 <div>{text}</div>
 );
});

Styling

We support both global styles with sass in ./src/client/stylesheets/main.scss and modular styles with styletron-react:

import react from 'react';
import {styled} from 'onefx/lib/styletron-react';

const Panel = styled('div', {
 backgroundColor: 'silver',
});

export default <Panel>Hello</Panel>;

Routing

server-side routing is using koa-router and located in ./src/server/server-routes.js. The basic usage is:

server
 .get('/', (ctx, next) => {
 ctx.body = 'Hello World!';
 })
 .post('/users', (ctx, next) => {
 // ...
 })
 .put('/users/:id', (ctx, next) => {
 // ...
 })
 .del('/users/:id', (ctx, next) => {
 // ...
 })
 .all('/users/:id', (ctx, next) => {
 // ...
 });

client-side routing is using react-router v4 and located in ./src/shared/app.js.

<Switch>
 <Route exact path='/' component={Home}/>
 <Route component={NotFound}/>
</Switch>

Fetching data

We use Apollo Graphql and TypeGraphQL for universal rendering with React. For detailed documentation, please visit:

Make a query

In src/api-gateway/resolvers/, define a new resolver and method. Take the meta data endpoint of the server health for example.

import { Query, Resolver, ResolverInterface } from "type-graphql";

@Resolver(_ => String)
export class MetaResolver implements ResolverInterface<() => String> {
 @Query(_ => String, { description: "is the server healthy?" })
 public async health(): Promise<string> {
 return "OK";
 }
}

and then in api-gateway.ts, mount the resolver.

 const resolvers = [MetaResolver];

Now the server is ready and you can call the health endpoint at https://localhost:5000/api-gateway/.

The next step is to call it from the React component.

Organizing components with data

Directory structure

.
├── components
│   └── health-text.tsx
├── data
│   ├── __generated__
│   │   └── health.ts
│   └── queries.ts // or / and mutations.ts
├── health-controller.tsx
├── hooks
│   └── use-health.ts
└── index.ts

components is for view components only, for example health-text.tsx

import { colors } from "@/shared/common/styles/style-color";
import CheckCircleTwoTone from "@ant-design/icons/CheckCircleTwoTone";
import CloseCircleTwoTone from "@ant-design/icons/CloseCircleTwoTone";
import LoadingOutlined from "@ant-design/icons/LoadingOutlined";
import React from "react";

type Props = {
 loading: boolean;
 health?: string;
 error: boolean;
};

export const HealthText: React.FC<Props> = ({
 loading,
 health,
 error
}: Props) => {
 if (loading) {
 return (
 <div>
 <LoadingOutlined /> Checking Status
 </div>
 );
 }
 if (error) {
 return (
 <div>
 <CloseCircleTwoTone twoToneColor={colors.error} /> Not OK
 </div>
 );
 }

 return (
 <div>
 <CheckCircleTwoTone twoToneColor={colors.success} /> {health}
 </div>
 );
};

data is for GraphQL queries and mutations. For example, health-controller.tsx. Whenever it changes, please run npm run schema:generate to generate type definitions again.

import gql from "graphql-tag";

export const getHealth = gql`
 query GetHealth {
 health
 }
`;

hooks are lifecyle functions for components

import { GetHealth } from "@/shared/home/data/__generated__/getHealth";
import { getHealth } from "@/shared/home/data/quries";
import { useQuery } from "react-apollo";

export const useGetHealth = () => {
 const { loading, data, error, refetch } = useQuery<GetHealth>(getHealth, {
 ssr: false
 });
 return { loading, data, error, refetch };
};

And finally *-controller.tsx connects data with view components via hooks.

import { useGetHealth } from "@/shared/home/hooks/use-health";
import React from "react";
import { HealthText } from "./components/health-text";

export const HealthController: React.FC = () => {
 const { loading, data, error } = useGetHealth();
 return <HealthText loading={loading} error={!!error} health={data?.health} />;
};

Internationalization

Onefx reads translations from ./translations directory. Please create a file there named with a corresponding locale, for example, en.yaml. And then add an entry

homepage.hello: hello, ${userName}!

React / Client-side

and then in the react view file (client-side)

import {t} from 'onefx/lib/iso-i18n';

function Greetings() {
 return (
 <div>{t('homepage.hello', {userName: 'John'})}</div>
 );
}

When users visit this site with accept-language: en in the header, which is set by the browser, then they will see translated greetings. If you want to explicitly set the locale, then visit the page with a query string ?locale=en then it will memorize this in the cookie.

Server-side

t singleton function does not work in the server-side because the async calls may switch the context and mix it with requests from other languages. In this case, please use ctx.t instead.

Testing

test files are supposed to be placed in any module like ./__test__/example.test.js in ava test utils.

import test from 'ava';

test('testname', async t => {
 // ...
});

Security

Onefx enables secure web app development with

CSRF protection that can be exempted at ./config/default.js (config.server.noCsrfRoutes)
Helmet headers that can be exempted at config.server.noSecurityHeadersRoutes
Content Security Policy configured at config.csp

for example, in default.js,

 server: {
 noSecurityHeadersRoutes: {
 '/embed/checkout/': true,
 },
 noCsrfRoutes: {
 '/api-gateway/': true,
 },
 },
 csp: {
 'default-src': [
 'none',
 ],
 }

Static assets

Static assets are placed in ./client/static/ and loaded into the root directory of the website. Take ./client/static/favicon.png for example, you can get it at http://localhost:4100/favicon.png, or use it in the react component:

import {assetURL} from 'onefx/lib/asset-url';

function ImgExample() {
 return (
 <img src={assetURL('favicon.png')}/>
 );
}

Configuration

Environment variables

The environment variable is read from commandline as well as .env file. Take PORT for example,

PORT=4004 npm run watch

or in .env file

PORT=4004

In the js file, you can read the value by process.env.PORT.

Static configuration

The static configuration is located in ./config and can be read according to the environment variable NODE_ENV.

CDN

If you want to setup CDN for the static resources, I recommend BunnyCDN for its ease-of-use and cost-effectiveness. Then configure OneFx as

module.exports = {
 // ...
 server: {
 // ...
 cdnBase: 'https://example-cdn.net',
 }
 // ...
}

And then when loading static assets, you just follow the same practice with the static assets.

import {assetURL} from 'onefx/lib/asset-url';

function ImgExample() {
 return (
 <img src={assetURL('favicon.png')}/>
 );
}
