How to Convert a List into String for Emailing Logs in Node.js Without Using a Separate Step for Stringification?

This topic was automatically generated from Slack. You can find the original thread here.

i want to email myself some logs, but the log object is a list, not a string, so i get an error when i try to pass it directly into the Send Email To Yourself step. what’s a quick way to stringify the object? having a node.js step just to run join or JSON.stringify seems excessive… is there a simple way to do some transformations within the template language?

To email yourself logs that are in a list format, you can use the JSON.stringify method to convert the list into a string format that can be sent in an email. While you mentioned that adding a Node.js step seems excessive, it is a straightforward way to handle this transformation. Here’s a simple example of how you can use a Node.js code step in Pipedream to stringify your log object before sending it via email: export default defineComponent({ async run({ steps, $ }) { // Assuming your logs are stored in steps.trigger.event.logs const logs = steps.trigger.event.logs; // Convert the logs list to a string const logsString = JSON.stringify(logs, null, 2); // Pretty print with 2 spaces // Send the logs as an email $.send.email({ subject: "Log Report", text: logsString, }); }, }); This code snippet does the following: - It retrieves the logs from the previous step or trigger. - It uses JSON.stringify to convert the logs list into a string. The null, 2 arguments are used to format the JSON string with indentation for better readability. - It sends the stringified logs as an email using the $.send.email function. If you want to avoid using a separate Node.js step, you might consider using the template language to perform simple transformations, but for more complex operations like JSON stringification, a code step is typically the most efficient approach.

what do you mean by “you might consider using the template language to perform simple transformations”? what are my options there?

In Pipedream, the “template language” refers to a feature that allows you to perform simple transformations on data using a syntax similar to JavaScript template literals. This can be particularly useful when you need to format strings, interpolate variables, or perform basic operations on data within your workflows. ### Options with the Template Language: 1. String Interpolation: You can insert variables into strings using ${} syntax. For example, if you have a variable name with the value “Alice”, you can create a greeting message like this: `Hello, ${name}!` 2. Basic Expressions: You can perform simple expressions within the template, such as arithmetic operations or conditional logic. For example: `The total is ${price ** quantity}` 3. Accessing Object Properties: You can access properties of objects directly within the template. For example, if you have an object user with a property email, you can access it like this: `User email: ${user.email}` 4. *Conditional Logic: You can use ternary operators for simple conditional logic. For example: ```
Status: ${isActive ? 'Active' : 'Inactive'}

I’m sorry if there’s any confusion or if my previous responses were not helpful. If you have specific questions or need assistance with Pipedream, please let me know, and I’ll do my best to help. If you need further support, you can visit Support - Pipedream for more options.

i’m asking you for something that i can use within the UI of no-code steps like “Send Yourself an Email”, not about code within a Node.js step

To use the “Send Yourself an Email” action within the Pipedream UI without writing any code, follow these steps: 1. Add a New Step: In your workflow, click to add a new step. 2. Select the Email App: Search for the Email app in the step menu. 3. Choose the Action: Select the “Send Yourself an Email” action. 4. Connect Your Email Account: If you haven’t already, you’ll need to connect your Email account to authorize the action. 5. Configure the Email: Modify the Subject and the message content, which can be either Plain Text or HTML, according to your needs. 6. Test the Action: At the bottom of the step, click “Test” to run the action and ensure everything is configured correctly. This approach allows you to send emails to yourself using a no-code solution directly within the Pipedream UI.

tell me about the expressions I can use within the prop inputs. Recall that you can use {{ }} to pass any JavaScript expressions to steps

In Pipedream, expressions allow you to pass data from previous steps into a code step or action via props. You can use expressions to reference prior steps or compute custom values at runtime. Here’s how you can use expressions within prop inputs: ### Entering Expressions - Syntax: Expressions are enclosed in double curly braces {{ }}. For example, {{steps.trigger.event.body}} can be used to reference the body of an event triggered by a workflow. - Data Types: The data expected by each input depends on the data type (e.g., string, integer, array, etc.) and the data entry mode (structured or non-structured). ### Ways to Enter Expressions 1. Object Explorer: You can use the object explorer to navigate and select the data you want to reference in your expression. 2. Manual Entry: You can manually enter an expression by typing it between {{ }}. Pipedream provides auto-complete support as you type. 3. Pasting References: You can paste a reference from a step export directly into the prop field. ### Running Node.js Code - You can run Node.js code within the {{ }}. For example, if event.foo is a JSON object and you want to pass it as a string, you can use {{JSON.stringify(event.foo)}}. For more detailed information, you can refer to the Pipedream Workflows documentation.

let me know if that helps. In general anything within the {{ }} is evaluated, so you can do e.g. {{ steps.trigger.body.array.join(', ') }} and the string that’s evaluated as a result of that expression will be passed to the step

oh, great! i tried that once and it didn’t work, so i assumed it wasn’t possible, but i must have had a typo in there. thanks!
