1-9: Good implementation, but consider adding input validation and sanitization.The
normalizeFilepathfunction effectively standardizes filepaths, which is great for consistency. However, to improve robustness and security, consider the following enhancements:
- Add input validation to ensure
filenameis a non-empty string.- Implement filename sanitization to prevent potential security issues with user-provided input.
Here's a suggested implementation with these improvements:
import path from 'path'; const normalizeFilepath = (filename, ext = "pdf") => { if (typeof filename !== 'string' || filename.trim() === '') { throw new Error('Invalid filename: must be a non-empty string'); } // Sanitize filename (remove any path traversal attempts) const sanitizedFilename = path.basename(filename); let filepath = sanitizedFilename.startsWith("/tmp") ? sanitizedFilename : `/tmp/${sanitizedFilename}`; // Remove any existing extension before adding the new one filepath = path.join(path.dirname(filepath), path.basename(filepath, path.extname(filepath))); return `${filepath}.${ext}`; };This implementation:
- Validates the input
- Sanitizes the filename using
path.basename()- Handles cases where the filename might already have a different extension
Note: This implementation assumes the
pathmodule is available. If it's not, you'll need to import it at the top of the file.
1-13: Overall assessment: Good addition with room for improvementThe
normalizeFilepathfunction is a valuable addition that aligns well with the PR objectives, particularly for handling file paths in PDF-related operations. It provides a consistent way to normalize file paths, which is crucial for the "Convert HTML to PDF" and "Merge PDFs" actions mentioned in the PR objectives.While the current implementation is functional, implementing the suggested improvements (input validation, sanitization, and handling of existing extensions) would significantly enhance its robustness and security.
Consider also adding unit tests for this function to ensure it handles various edge cases correctly.
components/customjs/actions/create-screenshot/create-screenshot.mjs (1)
5-24: LGTM: Action definition is well-structured and aligns with objectives.The action definition is comprehensive and includes all necessary properties. Good job on including a link to the documentation in the description.
Consider enhancing the description to provide more context about the action's functionality. For example:
- description: "Create a screenshot of a website. [See the documentation](https://www.customjs.space/api/docs#_3-create-screenshot)", + description: "Create a PNG screenshot of a specified website URL using the CustomJS API. [See the documentation](https://www.customjs.space/api/docs#_3-create-screenshot)",components/customjs/customjs.app.mjs (1)
14-30: LGTM: _makeRequest method is well-implemented. Consider adding error handling.The _makeRequest method is correctly implemented, using axios for HTTP requests and properly handling request options. The API key is securely used in the URL construction.
Consider adding error handling and a request timeout for improved robustness:
_makeRequest(opts = {}) { const { $ = this, headers, + timeout = 30000, // 30 seconds timeout ...otherOpts } = opts; - return axios($, { + return axios($, { + ...otherOpts, + method: "POST", + url: `https://e.customjs.io/__js1-${this.$auth.api_key}`, + headers: { + ...headers, + "Content-Type": "application/json", + }, + responseType: "arraybuffer", + timeout, + }).catch(error => { + console.error('Request failed:', error); + throw error; + }); }components/customjs/actions/merge-pdfs/merge-pdfs.mjs (1)
40-40: Specify buffer encoding for consistency.When creating a buffer from
fileContent, it's best to specify the encoding explicitly for clarity and consistency.Update the line as follows:
fs.writeFileSync(filepath, Buffer.from(fileContent, 'binary'));This ensures that the buffer is created with the correct encoding, matching the 'binary' data returned by the CustomJS API.

11-13: Export looks good.The
normalizeFilepathfunction is correctly exported, making it available for use in other modules.components/customjs/package.json (4)
3-3: Version update looks good.The increment from 0.0.1 to 0.1.0 appropriately reflects the addition of new features to the component.
14-14: JSON structure correction is appropriate.The addition of the closing brace properly completes the publishConfig object, ensuring valid JSON structure.
Line range hint
1-18: Overall, the package.json changes look good and align with the PR objectives.The version update, JSON structure correction, and dependency addition are all appropriate for setting up the new CustomJS component. These changes provide a solid foundation for implementing the new features mentioned in the PR objectives (convert HTML to PDF, create screenshot, merge PDFs).
Just ensure that the @pipedream/platform dependency is actually used in the component code as suggested in the previous comment.
15-18: Dependency addition looks appropriate, but usage verification needed.The addition of @pipedream/platform as a dependency is likely necessary for the new CustomJS component. However, please ensure that this dependency is actually used in the component code.
To verify the usage of @pipedream/platform, run the following script:
components/customjs/actions/convert-html-to-pdf/convert-html-to-pdf.mjs (2)
1-3: LGTM: Imports are appropriate for the task.The imports cover all necessary dependencies for the HTML to PDF conversion action:
customjsfor the conversion libraryfsfor file system operationsnormalizeFilepathutility for file path handling
5-10: LGTM: Action configuration is well-defined.The action configuration includes all necessary fields:
- Unique key: "customjs-convert-html-to-pdf"
- Descriptive name and description
- Version set to "0.0.1" for a new component
- Correct action type
The inclusion of a documentation link in the description is particularly helpful for users.
components/customjs/actions/create-screenshot/create-screenshot.mjs (1)
1-3: LGTM: Imports are appropriate and well-structured.The imports cover all necessary dependencies for the action's functionality:
- CustomJS app for API interaction
- File system module for writing the screenshot
- Utility function for filepath normalization
components/customjs/customjs.app.mjs (5)
1-5: LGTM: Import and app definition are correct.The import statement and app definition are properly structured and align with the expected format for a Pipedream app.
6-12: LGTM: Property definition for 'filename' is well-structured.The 'filename' property is correctly defined with appropriate type, label, and description. This aligns with the PR objectives, allowing users to specify a filename for downloading files to the
/tmpdirectory.
31-53: LGTM: convertHtmlToPdf, createScreenshot, and mergePdfs methods are correctly implemented.These methods align with the PR objectives for new CustomJS components. Each method:
- Correctly uses the _makeRequest method.
- Sets the appropriate 'customjs-origin' header.
- Allows flexible parameter passing using the spread operator.
The implementation is clean and consistent across all three methods.
Line range hint
54-57: LGTM: Proper closure of methods and app object.The methods object and app export are correctly closed, maintaining the proper structure of the module.
Line range hint
1-57: Overall, the CustomJS app implementation looks great!The changes in this file successfully implement the new components for CustomJS as outlined in the PR objectives. The code is well-structured, and the new methods (convertHtmlToPdf, createScreenshot, and mergePdfs) align perfectly with the requirements.
A minor suggestion for improvement has been made regarding error handling in the _makeRequest method, but this is not critical for the functionality.
Great job on implementing these new features!
components/customjs/actions/merge-pdfs/merge-pdfs.mjs (3)
1-3: LGTM: Imports are appropriate and well-structured.The imports cover all necessary dependencies for the module's functionality, including the custom app, file system operations, and utility functions.
5-12: LGTM: Action configuration is well-structured and informative.The action is properly configured with a clear key, name, description (including documentation link), version, and type. The
filenameprop is correctly defined using thecustomjsapp's prop definition.Also applies to: 18-24
25-47: LGTM: Overall implementation meets the PR objectives.The
runmethod successfully implements the PDF merging functionality as outlined in the PR objectives. It correctly handles the input, processes the PDFs using the CustomJS API, and saves the result to a file.
