Hey @keith!
I’ve been spending the last few days trying to “train” ChatGPT to help me build plugins. Been feeding it the Bubble plugin manual (such a sad little thing that is), posts from the forum and one or 2 YT transcripts on the subject. I just want to do a “peer review” with you about what I think it understands so far:
Start of ChatGPT explaining to me the differences about building a Bubble plugin
When developing a Bubble plugin, there are specific functions, practices, and structures you need to follow to ensure compatibility with the Bubble platform. Here’s a more detailed breakdown:
- Plugin Types:
- Bubble plugins can be one of two types: Element plugins or Action plugins.
- Element plugins create new visual elements or components.
- Action plugins define new actions or integrate third-party services.
- Initializing a Plugin:
- To initialize your plugin, you need to define an instance.data object in the
initialize
method. This object stores any data or state related to the plugin instance.
- Element Plugins:
- Element plugins require the definition of a
render
method. This method is called when the element is rendered on the page.
- Inside the
render
method, you can access the element’s properties via the properties
object and set up any event listeners.
- To update an element’s value or trigger a custom event, use the
instance.publishState
and instance.triggerEvent
methods, respectively.
- Action Plugins:
- Action plugins require the definition of a
function
for each action you want to create.
- The
function
must be named in the format actionName_run
. For example, if your action is called “Send Email,” the function should be named sendEmail_run
.
- Inside the action function, you can access the action’s properties via the
properties
object and call any necessary APIs or services.
- To return data or indicate that the action has completed, use the
instance.publishState
and instance.sendResult
methods, respectively.
- Exposing Properties:
- Both Element and Action plugins expose properties that users can configure within the Bubble editor.
- To expose properties, you need to define them in the Plugin Builder’s “Property Editor” section.
- The properties can be of various types, including text, number, boolean, color, date, etc.
- Users will configure these properties in the Bubble editor, and you’ll access their values using the
properties
object within your plugin code.
- Accessing Bubble APIs:
- When building a plugin, you might need to interact with Bubble’s APIs, such as fetching data from the Bubble database or triggering a Bubble workflow.
- To access these APIs, you’ll need to use the
instance.context
object and the associated methods, such as instance.context.request
, instance.context.uploadContent
, and others.
By following these specific structures and practices, you’ll ensure that your Bubble plugin is compatible with the platform and works seamlessly within Bubble apps.
Me: Is there anything about asynchronous actions that we should be careful of?
Yes, when working with asynchronous actions in Bubble plugins, it’s crucial to handle them properly to ensure smooth execution and prevent unexpected behavior. Here are some points to consider:
- Handling Promises:
- Asynchronous actions typically return Promises. Make sure you handle these Promises using
async/await
or then/catch
to manage the flow of your code.
- When using
async/await
, declare your function as async
. For example, for an action named “Fetch Data,” the function should be defined as async function fetchData_run(...) {...}
.
- Error Handling:
- Implement proper error handling using
try/catch
blocks when working with async/await
or catch
method for Promises. This helps prevent unhandled exceptions and provides meaningful error messages to users.
- Returning Results:
- When your asynchronous action is complete, use the
instance.sendResult
method to return the results to Bubble. This method accepts an object with key-value pairs representing the data you want to return.
- If you’re using
async/await
, call instance.sendResult
within a try
block after your asynchronous action is complete. For Promises, call it within the then
method.
- Reporting Progress:
- For long-running asynchronous actions, you can report progress to users by using the
instance.publishProgress
method. This allows you to display progress updates within the Bubble editor, keeping users informed.
- Timeouts:
- Be aware of potential timeouts. If your asynchronous action takes too long, it may exceed the timeout limit set by Bubble or the browser, leading to unexpected termination. Make sure your action handles such scenarios gracefully.
- Event Loop:
- Since JavaScript is single-threaded, long-running asynchronous actions can block the event loop and make the user interface unresponsive. Make sure to use appropriate techniques, like breaking down tasks into smaller chunks or using Web Workers, to avoid blocking the event loop.
By considering these points, you can create more robust and reliable asynchronous actions in your Bubble plugins, ensuring smooth integration with Bubble apps and a better user experience.
Me: How about callbacks and the context.async function?
In Bubble plugins, you can also use callbacks and the context.async
function to manage asynchronous actions. Here’s how to do it:
- Callbacks:
- You can use callbacks to handle asynchronous actions by passing a function as an argument to another function. This callback function will be invoked when the asynchronous operation is complete.
- When using callbacks in Bubble plugins, make sure you handle errors and pass them as the first argument to the callback function, following the Node.js convention.
- context.async:
- The
context.async
function is a utility provided by Bubble to help manage asynchronous code. It takes a single argument, which is a callback function.
- The callback function you pass to
context.async
should expect two arguments: an error and the result. The error argument should be null
if the operation is successful, otherwise, pass an error object.
- When you’re ready to return the result of your asynchronous action, call the callback function with the appropriate arguments (error and result).
- Note that the
context.async
function is not part of JavaScript itself, but a utility provided by Bubble specifically for plugin development.
Here’s an example using callbacks and context.async
in a Bubble plugin action:
javascriptCopy code
function myAsyncAction(instance, properties, context) {
// Define your asynchronous function, taking a callback as its argument
function fetchData(callback) {
someAsyncOperation()
.then((result) => {
callback(null, result); // Pass null as the error and result as the second argument
})
.catch((error) => {
callback(error); // Pass the error object as the first argument
});
}
// Use context.async to manage the callback
context.async(fetchData, function (error, result) {
if (error) {
instance.publishState("error", error.message); // Handle the error
instance.triggerEvent("error_occurred");
} else {
instance.publishState("result", result); // Publish the result
instance.triggerEvent("success");
}
});
}
Using callbacks and context.async
provides an alternative way to manage asynchronous actions in Bubble plugins. However, with the introduction of Promises and async/await
, these newer patterns are generally recommended for handling asynchronous code in JavaScript, as they can make the code more readable and easier to reason about.
