🧹 Nitpick comments (10)
components/pdf4me/actions/merge-pdfs/merge-pdfs.mjs (2)
32-40: Add validation for the response from the API.The code doesn't validate the response from the mergePdfs API call before attempting to save it.
const response = await this.pdf4me.mergePdfs({ $, data: { docContent: fileContents, docName: filename, }, responseType: "arraybuffer", }); + if (!response || response.length === 0) { + throw new Error("Received empty response from PDF4me API"); + }
41-45: Consider adding more detailed success information.The current success message is generic. Consider enhancing it with information about the number of files merged and the output file size.
const filedata = utils.downloadToTmp(response, filename); - $.export("$summary", "Successfully merged PDF files"); + $.export("$summary", `Successfully merged ${this.filePaths.length} PDF files into ${filename} (${response.length} bytes)`); return filedata;components/pdf4me/actions/convert-to-pdf/convert-to-pdf.mjs (2)
33-42: Add validation for the API response.The code should validate the response from the convertToPdf API call.
const response = await this.pdf4me.convertToPdf({ $, data: { docContent: fileContent, docName: this.filename, }, responseType: "arraybuffer", }); + if (!response || response.length === 0) { + throw new Error("Received empty response from PDF4me API"); + }
43-46: Enhance success message with file details.The current success message is generic. Consider enhancing it with information about the converted file.
const filedata = utils.downloadToTmp(response, this.filename); - $.export("$summary", "Successfully converted file to PDF"); + $.export("$summary", `Successfully converted ${this.filePath} to PDF (${response.length} bytes)`); return filedata;components/pdf4me/common/utils.mjs (2)
3-7: Improve path normalization logic.The current implementation assumes any path containing "tmp/" is already properly normalized, which may not be true for paths like "example/tmp/file.pdf".
function normalizeFilePath(path) { - return path.includes("tmp/") + return path.startsWith("/tmp/") || path.startsWith("tmp/") ? path : `/tmp/${path}`; }
9-13: Enhance extension checking logic.The current implementation doesn't handle cases where a filename might contain multiple dots or extensions.
function checkForExtension(filename, ext = "pdf") { - return filename.includes(`.${ext}`) + return filename.toLowerCase().endsWith(`.${ext.toLowerCase()}`) ? filename : `${filename}.${ext}`; }components/pdf4me/actions/compress-pdf/compress-pdf.mjs (2)
42-48: Consider using asynchronous file operationsUsing
fs.readFileSyncfor potentially large PDFs could block the Node.js event loop and cause performance issues.- const fileContent = fs.readFileSync(filePath, { - encoding: "base64", - }); + const fileContent = await fs.promises.readFile(filePath, { + encoding: "base64", + });
61-63: Add file size information to the summaryTo provide more value to users, consider adding the original and compressed file sizes to the summary message.
- $.export("$summary", "Successfully compressed PDF file"); + const originalSize = fs.statSync(filePath).size; + const compressedSize = fs.statSync(filedata.path).size; + const reductionPercent = ((originalSize - compressedSize) / originalSize * 100).toFixed(2); + $.export("$summary", `Successfully compressed PDF file from ${(originalSize/1024).toFixed(2)}KB to ${(compressedSize/1024).toFixed(2)}KB (${reductionPercent}% reduction)`);components/pdf4me/pdf4me.app.mjs (2)
19-21: Consider versioning the base URLBest practice is to include API version in the base URL method to make future version changes easier.
_baseUrl() { - return "https://api.pdf4me.com/api/v2"; + const API_VERSION = "v2"; + return `https://api.pdf4me.com/api/${API_VERSION}`; }
35-55: Implement consistent documentation for API wrapper methodsThe API methods would benefit from JSDoc comments to explain their parameters and return values.
+ /** + * Converts a document to PDF format + * @param {Object} opts - The options for the conversion + * @param {Object} opts.data - The data for the conversion + * @param {string} opts.data.docContent - The base64-encoded document content + * @param {string} opts.data.docName - The name of the document + * @returns {Promise<Object>} The API response + */ convertToPdf(opts = {}) { return this._makeRequest({ method: "POST", path: "/ConvertToPdf", ...opts, }); },Add similar documentation for the other methods.

42-48: Consider using asynchronous file operations.The code currently uses
fs.readFileSync()which blocks the event loop. In a Node.js environment, it's generally better to use asynchronous alternatives.- const fileContent = fs.readFileSync(filePath, { - encoding: "base64", - }); + const fileContent = await fs.promises.readFile(filePath, { + encoding: "base64", + });
59-63: Enhance the success message with compression details.The current success message is generic. Consider enhancing it with information about the original and compressed file sizes to give users more insight into the effectiveness of the compression.
- $.export("$summary", "Successfully compressed PDF file"); + const originalSize = fs.statSync(filePath).size; + const compressedSize = fs.statSync(filedata).size; + const compressionRatio = ((originalSize - compressedSize) / originalSize * 100).toFixed(2); + $.export("$summary", `Successfully compressed PDF from ${(originalSize/1024).toFixed(2)}KB to ${(compressedSize/1024).toFixed(2)}KB (${compressionRatio}% reduction)`);

1-4: LGTM! Import statements are well organized.The imports look appropriate for the functionality of this component, including the pdf4me app, utility functions, and filesystem module.
5-10: Component metadata is well-defined.The metadata includes an appropriate key, descriptive name, helpful documentation link, initial version (0.0.1), and correct component type.
11-41: Props are well-structured with comprehensive options.The props definition is clear and well-organized, with appropriate references to shared prop definitions and a well-defined set of compression options.
49-58: Add error handling for API callsThe API call lacks error handling. If the PDF4me API returns an error, the action will fail without a clear error message.
- const response = await this.pdf4me.compressPdf({ - $, - data: { - docContent: fileContent, - docName: filename, - optimizeProfile: this.optimizeProfile, - }, - responseType: "arraybuffer", - }); + try { + const response = await this.pdf4me.compressPdf({ + $, + data: { + docContent: fileContent, + docName: filename, + optimizeProfile: this.optimizeProfile, + }, + responseType: "arraybuffer", + }); + } catch (error) { + $.export("$summary", `Error compressing PDF: ${error.message}`); + throw error; + }

16-26: Add error handling to file download function.The downloadToTmp function should handle potential file system errors and validate inputs.
function downloadToTmp(response, filename) { + if (!response) { + throw new Error("Cannot download empty response"); + } + + if (!filename || typeof filename !== "string") { + throw new Error("Invalid filename provided"); + } const rawcontent = response.toString("base64"); const buffer = Buffer.from(rawcontent, "base64"); const filePath = normalizeFilePath(filename); - fs.writeFileSync(filePath, buffer); + + try { + fs.writeFileSync(filePath, buffer); + } catch (error) { + throw new Error(`Failed to write file to ${filePath}: ${error.message}`); + } return [ filename, filePath, ]; }components/pdf4me/pdf4me.app.mjs (1)
32-34:⚠️ Potential issueUse Basic Authentication for PDF4me.
According to the PDF4me documentation, the
Authorizationheader should containBasic <APIKey>rather than the raw key. This ensures compatibility with their API.Apply this diff to fix the header:
-headers: { - authorization: this.$auth.api_key, -}, +headers: { + Authorization: `Basic ${this.$auth.api_key}`, + "Content-Type": "application/json", +},

36-38: Ensure error details are surfaced.
utils.handleErrorMessage(error);may abstract or suppress some error context. Consider passing the HTTP status and response body to the thrown error for clarity, as previously suggested in past reviews.

1-2: Imports look good.No issues detected with the new imports from
@pipedream/platformand your local utilities file.
7-18: Properties are well-defined.The new
filePathandfilenameproperties correctly guide users to store files under/tmp. This aligns with typical usage in Pipedream. No concerns here regarding naming or data types.
20-22:❓ Verification inconclusive
Verify API version usage.
You're targeting
https://api.pdf4me.com/api/v2. Please confirm thatv2endpoints support all methods (/ConvertToPdf,/Merge,/Optimize) you plan to call.
🏁 Script executed:
#!/bin/bash # Description: Check for presence and validity of v2 endpoints. # Expect: references to ConvertToPdf, Merge, Optimize under v2 in PDF4me documentation. echo "Please verify with official docs or run a test request to confirm availability of these endpoints on v2."Length of output: 218
Attention: Verify API Version Endpoints
The base URL in
components/pdf4me/pdf4me.app.mjsis set to use the v2 API, but the current verification script only echoes a reminder. Please confirm—via the official PDF4me documentation or a test request—that the v2 endpoints (/ConvertToPdf,/Merge, and/Optimize) are indeed supported.
40-59:✅ Verification successful
POST methods look consistent.
convertToPdf,mergePdfs, andcompressPdfproperly pass their options to_makeRequest. Ensure the request bodies align with PDF4me-specific requirements (e.g., references to files, parameters).
🏁 Script executed:
#!/bin/bash # Description: Check method usage references in action files fd convert-to-pdf.mjs | xargs cat fd merge-pdfs.mjs | xargs cat fd compress-pdf.mjs | xargs cat # Inspect how you're constructing the body for these calls # Expect properly formed JSON with PDFs or relevant fields # as required by PDF4me documentation.Length of output: 7572
Action: PDF4me POST Request Bodies are Conforming
The PDF4me integration methods in
components/pdf4me/pdf4me.app.mjsare correctly constructing POST requests. Verification across the related action files confirms the following:
- convertToPdf: Reads the file from the specified path (encoding it in base64) and sends a request with
docContentanddocName.- mergePdfs: Constructs an array of base64-encoded file contents passed as
docContentalong with the document name (docName).- compressPdf: Includes the additional
optimizeProfilefield along withdocContentanddocNameas required.All request bodies align with PDF4me’s API expectations, and the file references/parameters are accurately provided.
