 5 | **THIS PROJECT IS UNDER DEVELOPMENT, DON'T USE IT ON PRODUCTION ENVIRONMENT.**
 6 | 
 7 | This is a NodeJS Server based on Express and cwebp, which allows you to serve WebP images on the fly.
 8 | 
 9 | > e.g When you visit `https://a.com/1.jpg`，it will serve as `image/webp` without changing the URL.
10 | >
11 | > For Safari and Opera users, the original image will be used.
12 | 
13 | ## Usage(Docker)
14 | 
15 | If you've docker installed, you can try build the package by doing as follows(don't worry, it's simple):
16 | 
17 | 1. Download the `docker-compose.yml` file to a folder you like, let's say `/home/nova/server1/`.
18 | 2. Edit the `docker-compose.yml`, at line 10 `./INTAKE` to the directory which contains your images.
19 | 3. run `docker-compose up -d` in that folder, this will run WebP Server with some parameters written in the `docker-compose.yml` and create the related folders.
20 | 4. Configure a NGINX server to reverse proxy it for public use.
21 | 
22 | That't it, the supervision and fail-over is handled by Docker Daemon, no more PM2s or NPMs are needed, Yay!
23 | 
24 | > Or, if you like the traditional way, see below.
25 | 
26 | ## Usage(Traditional)
27 | 
28 | Make sure you've installed `node` on your system, and the version of it shall be greater than 10, it will convert `jpg,jpeg,png` files by default, this can be customized by editing the `config.js`.
29 | 
30 | 1. Clone the repo and run `npm install` in it.
31 | 2. Make Sure you've install pm2, if not, use `npm install pm2 -g`
32 | 3. Define your pics folder on `config.js` (for instance there is a `1.jpg` in the related pic folder):
33 | 	```
34 | 	IMG_PATH: "/PATH/TO/pics",
35 | 	```
36 | 4. Run the APP with `pm2 start ecosystem.config.js --env production`, as this is a temporary solution to suppress errors, this should be fixed on later commits.
37 | 5. Let Nginx to `proxy_pass http://localhost:3333/;`
38 | 
39 | ## Detailed deploy instruction on a systemd based distros
40 | The following examples is tested under Ubuntu 18.04.
41 | ### 1. Install node
42 | ```shell script
43 | curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
44 | sudo apt-get install -y nodejs
45 | ```
46 | ### 2. Clone and install deps
47 | Refer to the previous usage section.
48 | ### 3. Add users
49 | ```shell script
50 | useradd -s /usr/sbin/nologin webp
51 | groupadd webp
52 | chown webp:webp -R /opt/webp_server/
53 | ```
54 | ### 4. systemd service
55 | ```shell script
56 | cp ./webp.service /lib/systemd/systemd/
57 | systemctl daemon-reload
58 | systemctl enable webp.service
59 | systemctl start webp.service
60 | ```
61 | ### 5. Nginx configuration
62 | Suppose you're using Wordpress and would like to serve Media images locate and edit your nginx configuration as follows
63 | ```
64 | location ^~ /wp-content/uploads/ {
65 |         proxy_pass http://127.0.0.1:3333;
66 | }
67 | ```
68 | where `wp-content/uploads` is your image path.
