Webview.cdp | LuaRT free and open source Windows programming framework for Lua

Webview.cdp readonly

Access a Chrome DevTools Protocol (CDP) function as a Lua table, calling it with a JSON string.
The CDP function will return a Task that, once finished, will return two values :

A boolean value indicating if the Chrome DevTools function succeeded
A string value representing either an error message in case of failure, or the result as a JSON encoded string

Notes

The Chrome DevTools Protocol is a set of tools and APIs that allow developers to interact with, inspect, debug, and profile Chromium-based browsers like the Webview.
You can access CDP functions seamlessly with this property, like Webview.cdp.Log.clear() to call Log.clear() CDP method
See Official documentation for a full reference.

Example


local ui = require "ui"
require "webview"

local win = ui.Window("Chrome Devtools Protocol example", "fixed", 320, 240)
local wv = ui.Webview(win, 0, 0, 320, 200)
local button = ui.Button(win, "Send a message to console log")
button:center()
button.y = 206
win:center()

function button:onClick()
    local success, result = await(wv.cdp.Runtime.evaluate('{"expression":"console.log(\'Hello from LuaRT !\')"}'))
    if not success then
      ui.error(result)
    else
      ui.info("Message sent !")
    end
end

function wv:onReady()
    self:opendevtools()
    self:loadstring([[
    <!DOCTYPE html>
    <html>
    <body>
        In the DevTools window, click on the Console tab to see the message.
    </body>
    </html>]])
end

ui.run(win):wait()
