# Quickly Run Examples

Foxit PDF SDK for Web comes with a lot of example projects and files for building the viewer and/or implementing additional functionality. These examples are provided in the ./examples folder of Foxit PDF SDK for Web. To run them, initialize your (local) web server, open your browser and add the localhost (http://localhost:port) or corresponding IP number URL. The directory list of files will be displayed and you can choose which sample to use.

To quickly get a web server running on your local system, you can use node.js http-server (opens new window):

http-server

Additionally, you can append the '-o' command to open directly in your browser window

http-server -o

You can also use Python's SimpleHTTPServe (opens new window) module:

python -m http.server 8000

You may want to refer to Set up local server (opens new window) for more information.

# Quickly run samples with Snapshot feature

To use some features that required a backend such as Snapshot and collaboration, your should run npm install and npm start to quicly start the http server and corresponding backend server at the same time. Below are steps in details.

Before running a sample, you may refer to the package.json file inside the SDK package, which looks a below:

"scripts": {
    "start": "concurrently --kill-others \"npm run start-http-server\" \"npm run start-snapshot-server\" \"npm run start-collaboration-server\"",
    "start-snapshot-server": "node ./server/snapshot/src/index -p 3002",
    "start-http-server": "node ./server/index",
    "start-collaboration-websocket-server": "node ./server/collaboration-websocket-server/src/index.js -p 9111",
    "start-collaboration-server": "node ./server/collaboration-sockjs-server/src/index.js -p 9112"
},

"serve": {
    "port": 8080,
    "public": "/",
    "proxy": {
        "target": "http://127.0.0.1:3002",
        "changeOrigin": true
    }
},
"collaboration-websocket": {
    "target": "http://127.0.0.1:9111",
    "changeOrigin": true,
    "ws": true
},
"collaboration-sockjs": {
    "target": "http://127.0.0.1:9112",
    "changeOrigin": true,
    "ws": true
}

Next check if and which version of the nodejs and npm are installed on in your computer:

node -v
v10.16.0
npm -v
6.14.1

Then install the dependencies declared in package.json:

npm install

Finally, run npm start command to start servive.

And visit http://127.0.0.1:8080 (opens new window) in browser, you can see all files and examples.
