Serve-my-app NPM

ServeMyApp

🚀 Serve your Javascript application and/or add an API to it in a minute!

This package allows you to add a NodeJS Express server easily and quickly to your Javascript application.

✨ Features:

Includes a fully customizable Express Server, which allows you to:

Serve your Javascript application, with routing handling.
Add directly your api routes into your project, without thinking to something else.

Getting started

In this ReadMe, we will take an example with a create-react-app application, and a @vue/cli one is coming. But it can be what you want, so please, let us know if you tested it with another framework or app. It will be added to this doc.

Installation

cd my-app
npm install serve-my-app express

Automatic initialisation

npx sma-init

Configuration

The serve-my-app binary will serve your frontend and your api.

It has several configuration parameters.

See usage section to understand how to use them.

Most useful ones:

Option	Type	Default value	Usage
--srv	string / false	`false`	Serve api routes from this folder (relative path)
--src	string / false	`false`	Serve your application from this folder (browser compatible files)
--watch	`false`	`false`	Restart server if change detected in `--srv` folder
--proxify	boolean	`false`	Proxify calls from your app to the express server (depends of you app dev server)

Other ones:

Option	Type	Default value	Usage
--host	string	`HOST` if set or `'0.0.0.0'`	Specify server host
--port	integer	`PORT` if set or `3001`	Specify server port
--https	boolean	`HTTPS` if set or `false`	Specify if displayed url should use https

Usage

Automatic initialisation

You really should use the sma-init command to configure your server, but see below to understand how tu use ServeMyApp

I only want to serve my frontend code in production

Build your application files (depends on your application framework/type):
```
 npm run build
```
Serve them.
```
 serve-my-app --src=build
```

Explanation:

--src: We're assuming that previous command will output compiled files to build folder.

I only want to add some api routes.

Create an api file as described below.
Serve it for development purpose:
```
serve-my-app --srv=srv --watch
```
Add your routes
Serve it for production:
```
serve-my-app --srv=srv
```

Explanation:

--srv: We're assuming that your api entrypoint is in srv folder.
--watch: Server will restart when a route will be added.

I want to serve both my frontend code and add some api routes.

Create an api file as described below.

Then :

For development purpose:
- Launch the server
```
  serve-my-app --srv=srv --proxify --watch
```
- Launch your frontend application (depends on your framework):
```
npm run start/serve
```
Explanation:
- --srv: We're assuming that your api entrypoint is in srv folder.
- --watch: Server will restart when a route will be added.
- --proxify: All the relative xhr/fetch calls made in the application will be proxyfied to the server.
To run the server only once for production:
- Build your app files (depends on your framework):
```
npm run build
```
- Launch the server
```
serve-my-app --srv=srv --src=build
```
Explanation:
- --srv: We're assuming that your api entrypoint is in srv folder.
- --src: We're assuming that previous command will output compiled files to build folder.

👍 In all cases, you can use relative urls for xhr/fetch calls in your code. 🚀 Again, all the ServeMyApp related commands and files can be generated using the sma-init cli tool.

FAQ

What should the server entrypoint look like?

It's a file exporting a function, which will receive the Express application as its first parameter, and the node http server as its second. With both you can do anything you want with your server.

For example:

const { json } = require('express');
const socketIO = require("socket.io");

module.export = (app, http) => {
    app.use(json());

    app.get('/foo', (req, res) => {
        res.json({msg: 'foo'});
    });

    app.post('/bar', (req, res) => {
        res.json(req.body);
    });
    
    socketIO(http).on("connection", client => {
      client.emit("message", "Welcome");
     });
}

I want to use some transpilation process for my server (Webpack, TypeScript...).

And you're right, it's a good idea!

In that case, you just have to handle the compilation process on your own, and specify an other folder for —srv files.

For example, for a TypeScript transpilation, and an "outDir": "../dist" in srv/tsconfig.json, you can update your script in package.json as:

"build:server": "rm -rf dist && tsc -p srv",
"sma": "serve-my-app --srv=dist [...]"

🤘 For Typescript transpilation ts-node will be used if your api entrypoint is detected as a typescript file. It allows you to use directly your typescript file for development:

"sma:dev": "serve-my-app --srv=srv --watch [...]"

😉 To help you in your Typescript development, you can import the ApiFunction type from 'serve-my-app':

import { ApiFunction } from 'serve-my-app'

const api: ApiFunction = (app, server) => {
 //
}

export default api

My `package.json` behaves in a weird manner: a `proxy` key comes and goes in it.

To proxify xhr calls from the front dev server to the express server, create-react-app uses a proxy key in the package.json. This is why this package adds it automatically if --proxify argument is provided.

This should be transparent for you, but if you want to disable it and handle yourself (or not) the proxy, you can do it by not passing the -—proxify flag.

You can find the documentation about proxies in create-react-app here.
