Scripts

"Scripts" are user-defined programs that run on the NEQTO device. With the use of libraries, users can define their own behavior to collect and send data.

Add a Script

  1. At the Scripts page, click the "Add Script" button in the top right corner.
  2. Give the Script a name and, optionally, a note on the first tab.
  3. If desired, assign the script a Library on the Libraries tab, and create Environment Variables on the Environment Variable tab.
  • Environment Variables allow you to store plain or secure variables for individual nodes, templates, or scripts.

Script Functions

There are various functions that can be performed when a Script is selected.

History

NEQTO saves a history of the last 10 times an edit has been made to a Script. From this window, the Script can be reverted to any of those last 10 versions. The last 10 versions can also be downloaded from this screen.

Replace

The Replace screen allows users to replace the contents of a Script with one from their computer. This function only accepts files with the .js extension.

Save

This button saves the currently loaded contents of the Script. The contents of a Script will be sent to devices on their next boot, or if they receive the Reload Script command.

Additional Settings

Script settings also includes a "library" function that supports linkage with external services such as AWS S3, Azure, and Dropbox, and an "environment variable" function for setting the API key required to use these services.

It is displayed that the setting tab is selected on the script selection screen.

Library

In neqto.js, libraries are not imported with “require” like in node.js and are instead loaded into a NEQTO device’s environment. You can add any needed libraries from the Script Editor.

Select the setting tab and select the library in the displayed modal window. It is displayed that S3 and various libraries are selected.

Environment Variable

Environment Variables are used to pass user-defined information such as UUIDS or secure information such as API Keys or passwords to scripts. The value is treated as a string. In the script, the value of environment variable can be accessed from the ENV object: ENV["Key name"]. Environment variable keys must be character strings- much like the key name of a JSON object.

  • The order of precedence for Environment Variables from highest to lowest is as follows: Nodes, Templates, Scripts.

Select the setting tab and select the environment variable in the displayed modal window. You can see that you are entering Environment Variables.

// Key: API_KEY, Value: YOUR_API_KEY
ENV["API_KEY"];  // => "YOUR_API_KEY"

// Key: INTERVAL, Value: 60
var interval = Number(ENV["TIMER_INTERVAL"]);  // => 60
