Gotalk in JavaScript
The JavaScript implementation of Gotalk currently only supports connecting over web sockets from modern web browsers. A future version might provide "listening" abilities and support for other environments like Nodejs.
Here's an example of connecting to a web server, providing a "prompt" operation (which the server can invoke at ay time to ask the user some question) and finally invoking a "echo" operation on the server.
gotalk.handle('prompt', function (params, result) {
var answer = prompt(params.question, params.placeholderAnswer);
result(answer);
})
// open a connection
const c = gotalk.connection()
// do stuff when the connection state changes
c.on("open", () => console.log("connection opened"))
c.on("close", () => console.log("connection closed"))
// make a request
let pong = await c.request("ping")
console.log("ping reply:", pong)
When using the gotalk.js
file (e.g. in a web browser), the API is exposed as window.gotalk
.
If the gotalk
directory containing the Gotalk CommonJS module is used, the API is returned as
an object from require('./gotalk')
.
See gotalk.d.ts
for documentation.
