WalkthroughThe changes introduce several new modules in the Beacon Chain component, each designed to retrieve specific data from the Beacon Chain API. These include actions for fetching epoch information, execution blocks, slot data, and validator details. Each module defines its own methods for constructing API requests and processing responses, enhancing the overall functionality of the Beacon Chain integration. Changes

8-12: LGTM! Consider adding value validationThe epoch property definition is well documented and aligns with the PR objectives. However, since it accepts specific string values ("latest", "finalized") or epoch numbers, consider adding validation.
Consider adding options validation:
epoch: { type: "string", label: "Epoch", description: "Epoch number, the string `latest` or the string `finalized`.", + validate: (value) => { + if (!value) return "Epoch is required"; + if (value !== "latest" && value !== "finalized" && isNaN(value)) { + return "Epoch must be a number or 'latest' or 'finalized'"; + } + return true; + }, },
15-37: LGTM! Consider enhancing error handlingThe API utility methods are well-structured, secure, and efficient. The authentication is properly handled, and the methods follow a consistent pattern.
Consider adding error handling with specific error types:
_makeRequest({ $ = this, path, headers, ...args } = {}) { + const handleError = (error) => { + if (error.response?.status === 429) { + throw new Error('Rate limit exceeded. Please try again later.'); + } + if (error.response?.status === 404) { + throw new Error(`Resource not found: ${path}`); + } + throw error; + }; + return axios($, { ...args, url: this.getUrl(path), headers: this.getHeaders(headers), - }); + }).catch(handleError); },components/beaconchain/actions/get-epoch/get-epoch.mjs (2)
18-27: Consider adding error handling for invalid epoch valuesThe implementation looks good but could benefit from basic validation before making the API request.
Consider adding validation:
methods: { getEpoch({ epoch, ...args } = {}) { + if (!epoch && epoch !== 0) { + throw new Error("Epoch parameter is required"); + } return this.app._makeRequest({ path: `/epoch/${epoch}`, ...args, }); }, },
28-41: Add try-catch block for better error handlingWhile the implementation is correct, adding error handling would improve reliability.
Consider adding error handling:
async run({ $ }) { const { getEpoch, epoch, } = this; + try { const response = await getEpoch({ $, epoch, }); $.export("$summary", `Successfully retrieved epoch \`${response.data.epoch}\`.`); return response; + } catch (error) { + throw new Error(`Failed to retrieve epoch: ${error.message}`); + } },components/beaconchain/actions/get-slots/get-slots.mjs (2)
3-8: Consider enhancing the description with usage examples.The component metadata is well-structured and follows Pipedream's conventions. The documentation link is helpful.
Consider adding example values or response format to the description to help users understand what to expect:
- description: "Returns all slots for a specified epoch. [See the documentation](https://beaconcha.in/api/v1/docs/index.html#/Epoch/get_api_v1_epoch__epoch__slots)", + description: "Returns all slots for a specified epoch (e.g., latest, finalized, or a specific number). Each slot contains details like status, proposer, and attestations. [See the documentation](https://beaconcha.in/api/v1/docs/index.html#/Epoch/get_api_v1_epoch__epoch__slots)",
9-18: Enhance the epoch prop description with validation details.The epoch description could be more informative about valid inputs and constraints.
Consider updating the description:
- description: "Returns all slots for a specified epoch.", + description: "The epoch to fetch slots for. Can be 'latest', 'finalized', or a specific epoch number. Note: Fetching slots for very old epochs might take longer.",components/beaconchain/actions/get-execution-blocks/get-execution-blocks.mjs (1)
17-26: Enhance method robustness and documentation.The method implementation could benefit from:
- Error handling for invalid block numbers
- Type checking for the blockNumber parameter
- JSDoc documentation
methods: { + /** + * Retrieves execution blocks from the Beacon Chain API + * @param {Object} params - The request parameters + * @param {string} params.blockNumber - Comma-separated block numbers + * @param {Object} [params.args] - Additional request arguments + * @returns {Promise<Object>} The API response + * @throws {Error} If blockNumber is invalid or missing + */ getExecutionBlocks({ blockNumber, ...args } = {}) { + if (!blockNumber) { + throw new Error("Block number is required"); + } return this.app._makeRequest({ path: `/execution/block/${blockNumber}`, ...args, }); }, },components/beaconchain/actions/get-validators/get-validators.mjs (1)
27-42: Enhance the success message and add error handling.
- The success message could be more informative by including the number of validators retrieved.
- The method should include proper error handling for API failures.
Consider these improvements:
async run({ $ }) { const { getValidators, indexesOrPubkeys, } = this; + try { const response = await getValidators({ $, indexOrPubkey: Array.isArray(indexesOrPubkeys) ? indexesOrPubkeys.map((value) => value.trim()).join(",") : indexesOrPubkeys, }); - $.export("$summary", "Successfully retrieved validators."); + const validatorCount = Array.isArray(response.data) ? response.data.length : 1; + $.export("$summary", `Successfully retrieved ${validatorCount} validator(s).`); return response; + } catch (error) { + throw new Error(`Failed to retrieve validators: ${error.message}`); + } },

3-3: LGTM! Version bump follows semantic versioning.
The version increment from 0.0.1 to 0.1.0 appropriately reflects the addition of new features for the beaconchain component.
15-17: Verify @pipedream/platform version.
Let's ensure we're using the latest stable version of @pipedream/platform.
✅ Verification successful
Version 3.0.3 is up to date with the latest stable version.
The component is using version 3.0.3 of @pipedream/platform which matches the latest version available from the npm registry. No update is needed.

1-2: Verify the constants file and its exports
The code imports constants that are crucial for API URL construction. Let's verify the constants file exists and contains the required exports.
✅ Verification successful
Constants file is properly structured and contains required exports
The constants file exists at the correct location and exports both BASE_URL and VERSION_PATH as expected, which are essential for API URL construction. The implementation follows good practices with proper constant separation and export structure.
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:

1-8: LGTM! Well-structured module metadata.
The metadata is well-defined with clear description and documentation link. The version number is appropriate for a new component.
9-17: Verify epoch prop definition in app file
Let's ensure the epoch prop definition in the app file aligns with the API requirements for epoch values (number or tags like "latest"/"finalized").
✅ Verification successful
Epoch prop definition is correctly implemented
The epoch prop definition in the app file properly validates the expected values. It's defined as a string type and explicitly documents in its description that it accepts both epoch numbers and special string values ('latest' or 'finalized'), which aligns with the API requirements.
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Check epoch prop definition in app file
# Expected: Should find prop definition with proper validation for epoch values
# Search for epoch prop definition
ast-grep --pattern 'epoch: {
type: $_,
$$$

1-8: LGTM! Well-structured component metadata.
The component metadata is well-defined with clear naming, appropriate versioning for a new component, and includes helpful documentation links.
1-43: Verify API endpoint compatibility.
Let's ensure the implementation aligns with the beaconchain API specifications.
✅ Verification successful
Let me gather more information about the API endpoint by checking the app file and documentation.
Let me check the constants file to verify the base URL and API version path.
API endpoint implementation is correct
The implementation correctly uses the Beaconchain API endpoint:
- Base URL:
https://beaconcha.in - API Version:
/api/v1 - Endpoint Path:
/execution/block/${blockNumber}
The code properly handles authentication via API key and supports multiple block numbers through comma-separated values, which aligns with the API documentation referenced in the component description.
