These node-red nodes expose puppeteer's API used for controlling Chrome/Chromium over the DevTools Protocol

Group	Node Name	Detailed information
Browser	Launch	Launch Chrome browser Inputs Timeout: number Maximum time in milliseconds to wait for the browser instance to start. Defaults to 30000 (30 seconds). Pass 0 to disable timeout. Slow Motion: number Slows down Puppeteer operations by the specified amount of milliseconds. Useful so that you can see what is going on. Hide Chrome: boolean Whether to run browser in headless mode. Defaults to false, it will show Chrome when devtools option is true. Debug Port: number Specify custom debugging port. It will connect to existing Chrome if port specified. Pass 0 to discover a random port. Defaults to 0. Show Devtools: boolean Whether to auto-open a DevTools panel for each tab. If this option is true , the Hide Chrome option will be set false. Outputs msg.puppeteer.browser: object The puppeteer browser object msg.puppeteer.page: object The puppeteer page object Details Must launch Chrome browser before run any puppeteer actions
Browser	New Page	This node creates/opens new page(tab) in existing chromium instance or rather puppeteer.browser object
Browser	Close Browser	This node closes chromium browser instance provided with puppeteer.browser object
Page	Click	Click on Chrome Inputs Selector: string A selectorto search for element to click. If there are multiple elements satisfying the selector, the first will be clicked. Button: string Slows down Puppeteer operations by the specified amount of milliseconds. Useful so that you can see what is going on.<"left"|"right"|"middle"> Defaults to left. Click Count: number Whether to run browser in  headless mode. Defaults to false, it will show Chrome when devtools option is true. Defaults to 1. See UIEvent.detail. Delay: number Specify custom debugging port. Pass 0  to discover a random port. Defaults to 0. Time to wait between mousedown and mouseup in milliseconds. Defaults to 0. Details This node fetches an element with selector, scrolls it into view if needed, and then uses page.mouse to click in the center of the element. If there's no element matching selector, the node throws an error.
Page	Close	Close first chromium page(tab) Details This node closes first chromium page(tab) provided with puppeteer.browser object
Page	Content	Get content from page Details This node gets page's content from puppeteer.page object
Page	Delete Cookies	This node deletes all the cookies from the passed puppeteer.page object
Page	Download	Dowload a file Inputs Selector: string A selector to search for element to click. If there are multiple elements satisfying the selector, the first will be clicked. Button: string Slows down Puppeteer operations by the specified amount of milliseconds. Useful so that you can see what is going on.<"left"|"right"|"middle"> Defaults to left. Click Count: number Delay: number Download path: string Specify custom download path. Leave the field blank for default download path. Defaults to user's default browser download path. File name: string Specify custom file name. Leave the field blank for default file name. Please note that in order for this to work this node needs to be followed by the rename node(in storage section). Defaults to default file name. Details This method fetches an element with selector, scrolls it into view if needed, and then uses page.mouse to click in the center of the element. If there's no element matching selector, the method throws an error. The main difference between this and click node is that with this node you can specify download path and file name. But, in order the custom filename to work, this node must have download path and file name specified and be followed by a rename node(in storage section)where the old file path should be set to msg.old and the new file path should be set to msg.new
Page	Focus	Focus on element Details This node fetches an element with selector and puts it in focus. If there's no element matching selector, the node throws an error.
Page	Get	Get property value from element Details This node fetches a specified property value from element with specified selector . If there's no element matching the selector, the node throws an error.
Page	Get Cookies	This node retrieves all cookies using the passed page object as input (msg.puppeteer.page). This node otputs list of cookies in msg.payload property. Each object contains the following properties: name: string value: string domain: string path: string expires: number size: number httpOnly: boolean secure: boolean session: boolean sameSite: string sameParty: boolean sourceScheme: string sourcePort: number
Page	Go to	Chrome page navigation Inputs URL: string URL to navigate page to. The URL should include scheme, e.g. https:// Wait Until: string When to consider navigation succeeded. Given an array of event strings, navigation is considered to be successful after all events have been fired. Events can be either: - load : consider navigation to be finished when the load event is fired. - domcontentloaded : consider navigation to be finished when the DOMContentLoaded event is fired. - networkidle0 : consider navigation to be finished when there are no more than 0 network connections for at least 500 ms. - networkidle2 : consider navigation to be finished when there are no more than 2 network connections for at least 500 ms.
Page	Screenshot	Capture Screen Inputs Capture Full Page: boolean When true, takes a screenshot of the full scrollable page. Defaults to false. Outputs msg.payload: Buffer buffer with captured screenshot. Details Browser screenshot, require focus / active to browser
Page	Set	Set value to input field Details This node fetches an element with selector and if the element is input field it changes its value to the value specified in the Value field. If there's no element matching selector, the node throws an error.
Page	Set Cookies	This node sets the cookies on the current page object. The input page object should be passed as msg.puppeteer.page. The cookies should be a list of cookie objects where each one has the following properties and they should be passed in as msg.payload, or if directly into the input field it should be a valid JSON list: name: string|required value: string|required domain: string|optional, Default value: '{domain from page object}' path: string|optional, Default value: '/' expires: number|optional, Default value: -1 size: number|optional, Default value: {cookie size} httpOnly: boolean|optional, Default value: false secure: boolean|optional, Default value: true session: boolean|optional, Default value: true sameSite: string|optional, Default value: undefined sameParty: boolean|optional, Default value: false sourceScheme: string|optional, Default value: 'Secure' sourcePort: number|optional, Default value: 443
Page	Upload	Upload file to specified selector Details This node uploads a file(or more accurately specified filePath) specified with Upload File to the element speicified with the selector if it exists.
Page	Wait for	Wait for selector Details This node awaits for element specified with selector. If the wait timeouts/element doesn't exist, this node throws an error
Keyboard	Press	Keyboard Press Details This node presses the keyboard key specified in Key input field.
Keyboard	Type	Keyboard Type Details This node types the text specified in the Text input using the puppeteer.page.keyboard.type function.
Storage	Rename	Rename file Inputs Old file path: string New file path: string Details This node renames the file from old file path to the new file path, or essetially it moves it from one location to another if that is how the paths are specified.
