Hey folks,
I really love using Postman with the dark theme. I was trying my hand at the visualizer and all I could see in that tab is a black screen, it took a while for me to realize that it was probably because of the dark theme. Once I changed the theme to the lighter one, I could see all the html elements with their expected styles under the visualizer.
I just wanted to discuss about the user experience. Every user who likes using Postman with the dark theme would have to switch to the lighter theme while visualizing. Is it possible to have the visualizer space with a white background?
If you see [Roslyn] in your code tabs in Visual Studio, then you can use the visualizer. Another way of verifying if Roslyn is enabled is to view your extensions. The Roslyn Language Services has to be there for it to work. If this is not the case, then the visualizer can be opened, but it won't show any contents.
To visualize your response data, add code to the Pre-request or Tests script for the request. The pm.visualizer.set() method will apply your Visualizer code to the data and present it in the Visualize tab when the request runs.
The pm.visualizer.set() method accepts a Handlebars template string as its first parameter. The second parameter is the data you want to use the template to display. Read on to learn how you can build a Handlebars template and pass data to it.
The variable names inside the double curly braces in the template will be substituted by the data passed to the pm.visualizer.set() method. To apply the template, the following code completes the Tests script:
Any elements inside your template can access the data passed in the second argument to pm.visualizer.set() by calling the pm.getData(callback) method. This is only applicable to JavaScript code in the template, for example if your template includes code to render a chart.
The pm.getData(callback) method takes a callback function as its parameter. This callback accepts two parameters: error and data. The second parameter is the data that was passed to pm.visualizer.set().
Postman uses the information you pass to pm.visualizer.set() to render an HTML page in the sandbox for the Visualizer. Select the Visualize tab for the rendered HTML page. The layout string is inserted into the of the rendered page, including any JavaScript, CSS, and HTML that the template has.
