Use Inspector

In this how-to guide, we will take a look at Inspector of the app-builder and see how it can be helpful in building applications.

The Inspector can be used to inspect the data of the queries, properties and values of the components that are there on the canvas, ToolJet's global variables and the variables that have been set by the user.

How to - Use Inspector


Let's take a look at the layout of the Inspector panel:

  • On the top-right, we have a Pin button to pin and unpin the inspector panel. This button can be useful when you want to see the live changes on inspector while triggering a query or performing some event/action on any component.

    How to - Use Inspector
  • At the bottom right, you can click and hold to resize the inspector.

  • On hovering an item on the inspector, the copy path and copy value buttons will appear on the right of the item. Copying the path and pasting it onto the component property or query parameter will always get the dynamic value but using Copy value option will copy the current value of the item and will be static when pasted in a component property or query parameter.

The Inspector panel has the following 4 main sections:


The queries section can be used to inspect the query details but the data of the query will only be available if query has been run/triggered.


You can click on the Preview button of the button on the query manager to check the response(data) of the query without triggering it.


  • Let's create a new query using a mock REST API endpoint (

  • Now go to the Inspector and expand the queries section, you'll see an entry inside queries with the query name that we created in the previous step i.e. restapi1 but if you notice the data and rawData object is empty i.e. 0 entry. The reason is the data won't show up on the inspector unless query is run.

    How to - Use Inspector
  • Let's pin the inspector and then trigger the query from the query manager. You'll see that as soon as the query is triggered the rawData and data object in the query has 20 entries and the query has more properties like request, response, and responseHeaders data.

components section can be used to inspect the properties and values of the components that are added onto the canvas.

The globals section consists of the following sub-sections:

  • currentUser: The currentUser object contains information about the currently logged-in user, such as their email, firstName, and lastName.
  • groups: The groups array contains the names of the groups to which the currently logged-in user belongs. Note: The all_users group is a default group for everyone.
  • theme: The theme object contains the name of the currently active theme.
  • urlparams: The urlparams contain information about the URL parameters of the application.
  • environment: This variable holds two keys: id and name. The id is a unique identifier generated automatically, and the name holds the name of the currently opened environment of the app version.
  • modes: This variable holds one of three values: edit, preview, or view, depending on the current state of the app. If the app is opened in editing mode, the mode will be set to edit. If the app is opened by clicking the preview button on the app builder, the variable will be set to preview. If the app is opened using the URL from the Share modal, the mode will be set to view.

The environment and mode variables are only available in ToolJet Enterprise Edition v2.2.3 and above.

All the global variables can be accessed anywhere within ToolJet applications. Here's an example use-case that demonstrates the usage of these variables.


variables section include all the variables set by the user in the application. These variables can be set from the event handlers from the components or from the queries. The variables will be in the key-value pair and can be accessed throughout the application.
