Walkthrough

This pull request introduces a comprehensive implementation of OCR.space components for Pipedream, focusing on image and PDF processing. The implementation includes a base processing module, specific actions for image and PDF processing, utility functions, constants for language and file type options, and an enhanced application configuration. The new components provide flexible OCR processing capabilities with configurable parameters like language, file type, orientation detection, and OCR engine selection.

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

🧹 Nitpick comments (4)
components/ocrspace/actions/process-image/process-image.mjs (1)

7-7: Enhance the description with supported file types.

The description could be more helpful by mentioning the supported image file types (GIF, PNG, JPG, TIF, BMP).

-  description: "Submits an image file for OCR processing using OCR.space. [See the documentation](https://ocr.space/ocrapi)",
+  description: "Submits an image file (GIF, PNG, JPG, TIF, BMP) for OCR processing using OCR.space. [See the documentation](https://ocr.space/ocrapi)",
components/ocrspace/common/utils.mjs (1)

4-12: Simplify URL validation using URL constructor.

The current regex pattern is complex and hard to maintain. Consider using the built-in URL constructor for more reliable URL validation.

-export const isValidUrl = (urlString) => {
-  var urlPattern = new RegExp("^(https?:\\/\\/)?" + // validate protocol
-    "((([a-z\\d]([a-z\\d-]*[a-z\\d])*)\\.)+[a-z]{2,}|" + // validate domain name
-    "((\\d{1,3}\\.){3}\\d{1,3}))" + // validate OR ip (v4) address
-    "(\\:\\d+)?(\\/[-a-z\\d%_.~+]*)*" + // validate port and path
-    "(\\?[;&a-z\\d%_.~+=-]*)?" + // validate query string
-    "(\\#[-a-z\\d_]*)?$", "i"); // validate fragment locator
-  return !!urlPattern.test(urlString);
+export const isValidUrl = (urlString) => {
+  try {
+    new URL(urlString);
+    return true;
+  } catch (err) {
+    return false;
+  }
};
components/ocrspace/ocrspace.app.mjs (2)

73-81: Add request timeout and retries.

The _makeRequest method should implement timeout and retry logic for better reliability.

    _makeRequest({
-     $ = this, path, headers, ...opts
+     $ = this, path, headers, timeout = 30000, retries = 3, ...opts
    }) {
-     return axios($, {
-       url: this._baseUrl() + path,
-       headers: this._headers(headers),
-       ...opts,
-     });
+     const makeRequestWithRetry = async (attempt = 1) => {
+       try {
+         return await axios($, {
+           url: this._baseUrl() + path,
+           headers: this._headers(headers),
+           timeout,
+           ...opts,
+         });
+       } catch (error) {
+         if (attempt === retries) throw error;
+         await new Promise(resolve => setTimeout(resolve, 1000 * attempt));
+         return makeRequestWithRetry(attempt + 1);
+       }
+     };
+     return makeRequestWithRetry();
    },

15-15: Enhance file property description.

The description for the file property should include supported file formats and size limits.

-      description: "The URL of the image or the path to the file saved to the `/tmp` directory  (e.g. `/tmp/example.jpg`)  to process. [See the documentation](https://pipedream.com/docs/workflows/steps/code/nodejs/working-with-files/#the-tmp-directory).",
+      description: "The URL of the image or the path to the file saved to the `/tmp` directory (e.g. `/tmp/example.jpg`). Supports PNG, JPG, GIF, TIF, BMP formats and PDF documents. Maximum file size: 1MB for free API key, 100MB for paid API key. [See the documentation](https://pipedream.com/docs/workflows/steps/code/nodejs/working-with-files/#the-tmp-directory).",

components/ocrspace/common/constants.mjs (1)

100-106: Consider adding support for modern image formats.

The list of supported image formats could be expanded to include modern formats like WEBP, if supported by the OCR.space API.

Let's verify the supported formats in the OCR.space API documentation:

components/ocrspace/actions/common/process-base.mjs (1)

67-67: ⚠️ Potential issue

Add error handling for getSummary method.

The code calls this.getSummary() but there's no implementation visible. This could throw an error if not properly implemented.

Add the getSummary method to the exported object:

export default {
  props: {
    // ... existing props
  },
  methods: {
+   getSummary() {
+     return "Successfully processed image with OCR.space";
+   },
  },
  async run({ $ }) {
    // ... existing run method
  },
};

Likely invalid or redundant comment.

components/ocrspace/ocrspace.app.mjs (1)

67-72: 🛠️ Refactor suggestion

Add content-type validation in headers.

The _headers method should validate and ensure proper content-type headers for form-data requests.

    _headers(headers = {}) {
+     const contentType = headers['content-type'];
+     if (!contentType?.includes('multipart/form-data')) {
+       throw new Error('Content-Type must be multipart/form-data for OCR.space API');
+     }
      return {
        "apikey": this.$auth.apikey,
        ...headers,
      };
    },

Likely invalid or redundant comment.
