  - Zero-configuration – It Just Works 🤞™.

  - Develop and test with automatically-provisioned locally-trusted TLS thanks to [mkcert](https://github.com/FiloSottile/mkcert) via [Nodecert](https://source.ind.ie/hypha/tools/nodecert).

  - Stage and deploy with automatically-provisioned globally-trusted TLS thanks to [Let’s Encrypt](https://letsencrypt.org/) via [ACME TLS](https://source.ind.ie/hypha/tools/acme-tls) (with an A score on [SSL Labs SSL Server Test](https://www.ssllabs.com/ssltest)).

[Watch a short 4-minute video](https://ar.al/2019/03/14/introducing-indie-web-server-video/) demonstrating how easy it is to install and use Indie Web Server.
14 15

## Install
Aral Balkan's avatar
Aral Balkan committed
16 17

```sh
Aral Balkan's avatar
Aral Balkan committed
18
npm i -g @ind.ie/web-server
Aral Balkan's avatar
Aral Balkan committed
19 20
```

21
## Use
22

23
### Command-line
Aral Balkan's avatar
Aral Balkan committed
24

25 26 27
Start serving the current directory at https://localhost:

```shell
Aral Balkan's avatar
Aral Balkan committed
28
$ web-server
29 30 31 32 33
```

Start serving the _site_ directory at your hostname:

```shell
Aral Balkan's avatar
Aral Balkan committed
34
$ web-server site --global
35 36
```

Aral Balkan's avatar
Aral Balkan committed
37
For example, if you run the command on a connected server that has the ar.al domain pointing to it and `ar.al` set in _/etc/hostname_ (on Unix/Linux/macOS), you will be able to access the site at https://ar.al. The first time you hit it, it will take a little longer to load as your Let’s Encrypt certificates are being automatically provisioned by ACME TLS.
38

39 40 41 42 43 44
## Build and test from source

```shell
# Clone and install.
git clone https://source.ind.ie/hypha/tools/web-server.git
cd web-server
45 46
npm i         # Install modules and development dependencies.
npm i -g .    # Install globally for access to the binary.
47 48 49 50 51 52 53 54

# Run unit tests.
npm test

# Serve the test site (visit https://localhost to view).
web-server test/site
```

55
## Syntax
56

Aral Balkan's avatar
Aral Balkan committed
57
```sh
Aral Balkan's avatar
Aral Balkan committed
58
web-server [folder-to-serve] [--port N] [--global] [--version]
Aral Balkan's avatar
Aral Balkan committed
59
```

All command-line arguments are optional. By default, Indie Web Server will serve your current working folder over port 433 with locally-trusted certificates.
62

63
If you specify the `--global` flag, globally-trusted Let’s Encrypt TLS certificates are automatically provisioned for you using ACME TLS the first time you hit your hostname. The hostname for the certificates is automatically set from the hostname of your system (and the _www._ subdomain is also automatically provisioned).

## Native 404 → 302 support for an evergreen web

What if links never died? What if we never broke the Web? What if it didn’t involve any extra work? It’s possible. And easy. Just make your 404s into 302s.

Aral Balkan's avatar
Aral Balkan committed
69
Indie Web Server has native support for [the 404 to 302 technique](https://4042302.org) to ensure an evergreen web. Just serve the old version of your site (e.g., your WordPress site, etc.) from a different subdomain and tell Indie Web Server to forward any unknown requests on your new static site to that subdomain so that all your existing links magically work.
70 71 72

To do so, create a simple file called `4042302` in the root directory of your web content and add the URL of the server that is hosting your older content. e.g.,

73
### /4042302
74
```
Aral Balkan's avatar
Aral Balkan committed
75
https://the-previous-version-of.my.site
76
```
77 78 79 80 81 82

You can chain the 404 → 302 method any number of times to ensure that none of your links ever break without expending any additional effort to migrate your content.

For more information and examples, see [4042302.org](https://4042302.org).

## Custom error pages
83

84 85
![Screenshot of the custom 404 error page included in the unit tests](images/custom-404.png)

86 87 88 89
You can specify a custom error page for 404 (not found) and 500 (internal server error) errors. To do so, create a folder with the status code you want off of the root of your web content (i.e., `/404` and/or `/500`) and place at least an `index.html` file in the folder. You can also, optionally, put any assets you want to display on your error pages into those folders and load them in via relative URLs. Your custom error pages will be served with the proper error code and at the URL that was being accessed.

If you do not create custom error pages, the built-in default error pages will be displayed for 404 and 500 errors.

90 91
When creating your own servers (see [API](#API)), you can generate the default error pages programmatically using the static methods `WebServer.default404ErrorPage()` and `WebServer.default500ErrorPage()`, passing in the missing path and the error message as the argument, respectively to get the HTML string of the error page returned.

92
## API
93

94
Indie Web Server’s `createServer` method behaves like the built-in _https_ module’s `createServer` function. Anywhere you use `require('https').createServer`, you can simply replace it with `require('@ind.ie/web-server').createServer`.
95

96

97
### createServer([options], [requestListener])
98

99
  - __options__ _(object)___:__ see [https.createServer](https://nodejs.org/api/https.html#https_https_createserver_options_requestlistener). Populates the `cert` and `key` properties from the automatically-created [nodecert](https://source.ind.ie/hypha/tools/nodecert/) or Let’s Encrypt certificates and will overwrite them if they exist in the options object you pass in. If your options has `options.global = true` set, globally-trusted TLS certificates are obtained from Let’s Encrypt using ACME TLS.
100

101
  - __requestListener__ _(function)___:__ see [https.createServer](https://nodejs.org/api/https.html#https_https_createserver_options_requestlistener). If you don’t pass a request listener, Indie Web Server will use its default one.
102

103
    __Returns:__ [https.Server](https://nodejs.org/api/https.html#https_class_https_server) instance, configured with either locally-trusted certificates via nodecert or globally-trusted ones from Let’s Encrypt.
104

105
#### Example

108
const webServer = require('@ind.ie/web-server')
109 110 111 112 113
const express = require('express')

const app = express()
app.use(express.static('.'))

114
const options = {} // to use globally-trusted certificates instead, set this to {global: true}

115
const server = webServer.createServer(options, app).listen(443, () => {
116 117 118 119
  console.log(` 🎉 Serving on https://localhost\n`)
})
```

120
### serve([options])
121 122

Options is an optional parameter object that may contain the following properties, all optional:
123

124
  - __path__ _(string)___:__ the directory to serve using [Express](http://expressjs.com/).static.
125

126 127 128 129
  - __callback__ _(function)___:__ a function to be called when the server is ready. If you do not specify a callback, you can specify the port as the second argument.

  - __port__ _(number)___:__ the port to serve on. Defaults to 443. (On Linux, privileges to bind to the port are automatically obtained for you.)

130
  - __global__ _(boolean)___:__ if true, globally-trusted Let’s Encrypt certificates will be provisioned (if necesary) and used via ACME TLS. If false (default), locally-trusted certificates will be provisioned (if necesary) and used using nodecert.
131 132

    __Returns:__ [https.Server](https://nodejs.org/api/https.html#https_class_https_server) instance, configured with either locally or globally-trusted certificates.

## Contributing

Indie Web Server is, by design, a zero-configuration personal web server for single-tenant web applications for and by individuals. As such, as new feature requests will have to be both fit for purpose and survive a trial by fire to be considered. (That is, this is [Small Tech](https://ar.al/2019/03/04/small-technology/), with the emphasis on _small_).

Please file issues and submit pull requests on the [Indie Web Server Github Mirror](https://github.com/indie-mirror/indie-web-server).

For locally-trusted certificates, all dependencies are installed automatically for you if they do not exist if you have apt, pacman, or yum (untested) on Linux or if you have [Homebrew](https://brew.sh/) or [MacPorts](https://www.macports.org/) (untested) on macOS.

I can use your help to test Indie Web Server on the following platform/package manager combinations:
162

163 164
  - Linux with yum
  - macOS with MacPorts

Please [let me know how/if it works](https://github.com/indie-mirror/web-server/issues). Thank you!

Also, automatic hostname detection has not been implemented for Windows and so globally-trusted certificates will fail on that platform. If you get to it before I do, [I would appreciate a pull request](https://github.com/indie-mirror/web-server/pulls).

  * [Tim Knip](https://github.com/timknip) for confirming that [the module works with 64-bit Windows](https://github.com/indie-mirror/https-server/issues/2) with the following behaviour: “Install pops up a windows dialog to allow adding the cert.”

  * [Run Rabbit Run](https://hackers.town/@nobody) for [the following information](https://hackers.town/@nobody/101670447262172957) on 64-bit Windows: “Win64: works with the windows cert install popup on server launch. Chrome and ie are ok with the site then. FF 65 still throws the cert warning even after restarting.”
