Use Cases & Code Samples

Overview

This guide presents use cases and code samples for leveraging the Pepperi JS Client Side API. One key use case is concatenating filter objects for the <resource>.search function, simplifying the construction of complex filters with a reusable helper function.

Use Case: Concatenating Filters

• Description: When using the <resource>.search function (e.g., peppi.api.attachments.search), you can build filter objects to query multiple conditions. The helper function below facilitates the concatenation of filter nodes, supporting both AND and OR operations.

• Helper Function:

  function concatFilters(f1, f2, and) {
    return {
      "Operation": (and ? "AND" : "OR"),
      "LeftNode": f1,
      "RightNode": f2
    };
  }

  • Parameters:

    • f1: First filter object.

    • f2: Second filter object.

    • and: Boolean to determine operation (true for AND, false for OR).

• Code Sample:

  var uuids = // your attachments in an array (e.g., ["uuid1", "uuid2", "uuid3"]);
  var filter = { "Operation": "IsEqual", "ApiName": "UUID", "Values": [uuids[0]] };
  for (var i = 1; i < uuids.length; i++) {
    filter = concatFilters(filter, 
      { "Operation": "IsEqual", "ApiName": "UUID", "Values": [uuids[i]] });
  }
  // Use the filter in a search function, e.g.:
  peppi.api.attachments.search({ filter: filter, responseCallback: "myCallback" });

• Explanation: This code initializes a filter with the first UUID and iteratively concatenates additional UUID filters using AND operations, building a chain of equality conditions.

Use Case: Console.log as Response Callback Function

• Description: Simplifies testing API requests in the browser console by using console.log as a responseCallback instead of defining a separate function, reducing unnecessary code.

• Traditional Approach:

  pepperi.app.transactions.removeLines({
    transaction: { UUID: "11cda91f-df09-4d3c-826d-184e5f394d06" },
    lines: [
      { UUID: "74667b10-25f8-48bd-8a08-66f682e2a45c" },
      { UUID: "4dd8b710-af0d-4357-b697-d28bffe2f21e" },
    ],
    responseCallback: "test",
  });
  
  function test(params) {
    console.log(params);
  }

• Optimized Approach:

  pepperi.app.transactions.removeLines({
    transaction: { UUID: "11cda91f-df09-4d3c-826d-184e5f394d06" },
    lines: [
      { UUID: "74667b10-25f8-48bd-8a08-66f682e2a45c" },
      { UUID: "4dd8b710-af0d-4357-b697-d28bffe2f21e" },
    ],
    responseCallback: "console.log",
  });

• Benefit: Achieves the same result with less code, logging the response directly to the console.

Use Case: Easy Retrieve Transaction UUID

• Description: Simplifies obtaining the transaction UUID for API testing by extracting it from the current URL using window.location.href.split('/')[5], avoiding manual copying.

• Syntax:

  window.location.href.split('/')[5]

• Example Usage:

  pepperi.app.transactions.removeLines({
    transaction: { UUID: window.location.href.split('/')[5] },
    lines: [
      { UUID: "74667b10-25f8-48bd-8a08-66f682e2a45c" },
      { UUID: "4dd8b710-af0d-4357-b697-d28bffe2f21e" },
    ],
    responseCallback: "console.log",
  });

• Benefit: Automates UUID retrieval from the URL, improving testing efficiency.
