Critical: Duplicate pdfmake import creates ambiguity.

Line 9 already imports pdfmake from the package root, but line 38 imports pdfMake (with different casing) from a specific build path. This creates confusion about which import is authoritative and may lead to unexpected behavior.

Recommended fix: Remove the duplicate import and use a consistent naming approach. Based on common pdfmake usage patterns, consolidate to a single import:

-// Import fonts
-import pdfMake from 'pdfmake/build/pdfmake';
-import pdfFonts from 'pdfmake/build/vfs_fonts';
+// Import fonts for pdfMake
+import pdfFonts from 'pdfmake/build/vfs_fonts';

Then update line 45 to use the existing pdfmake import:

-pdfMake.vfs = pdfFonts.vfs ?? pdfFonts.default?.vfs;
+pdfmake.vfs = pdfFonts.vfs ?? pdfFonts.default?.vfs;

However, verify the correct import pattern for pdfmake 0.2.18 first, as the package structure may have specific requirements.

🏁 Script executed:

#!/bin/bash
# Verify the correct import pattern and font setup for pdfmake 0.2.18

# Check package.json for pdfmake version
cat package.json | jq '.dependencies.pdfmake, .devDependencies.pdfmake'

# Look for other usages of pdfmake/pdfMake in the codebase
rg -n "import.*pdfmake" --type=js

# Check if there are any configuration files or documentation about pdfmake setup
fd -e js -e md -e txt README pdfmake

Based on my verification of the correct pdfMake import pattern for browser/ES6 modules, which requires `import pdfMake from "pdfmake/build/pdfmake"` and `pdfMake.vfs = pdfFonts.pdfMake.vfs`, the review comment identifies a real issue but requires refinement:

**Remove duplicate pdfmake import and correct font vfs assignment.**

Line 9's `import pdfmake from 'pdfmake'` is incorrect for browser usage—it's the server-side Node.js entry point, not for ES6 browser modules. Line 38's import from `'pdfmake/build/pdfmake'` is correct. Additionally, line 45's font assignment should use `pdfFonts.pdfMake.vfs` not `pdfFonts.vfs`, as confirmed in the pdfmake-font-generator documentation pattern.

**Fix required at line 9:** Remove the entire import statement.

**Fix required at line 45:** Change `pdfMake.vfs = pdfFonts.vfs ?? pdfFonts.default?.vfs;` to `pdfMake.vfs = pdfFonts.pdfMake.vfs;`

pdfmake 0.2.18 correct import and fonts setup

💡 Result:

Use the pdfmake 0.2.x docs approach. Minimal working examples:

Client (browser / ES module)

• import pdfMake and the built vfs fonts, then attach the vfs:
  import pdfMake from 'pdfmake/build/pdfmake';
  import pdfFonts from 'pdfmake/build/vfs_fonts';
  pdfMake.vfs = pdfFonts.pdfMake.vfs;
• register custom font metadata (optional) before createPdf:
  pdfMake.addFonts({
  MyFont: {
  normal: 'MyFont-Regular.ttf',
  bold: 'MyFont-Bold.ttf',
  italics: 'MyFont-Italic.ttf',
  bolditalics: 'MyFont-BoldItalic.ttf'
  }
  });
• use in docDefinition: defaultStyle: { font: 'MyFont' } then pdfMake.createPdf(docDefinition).download();

Alternate client import (TypeScript / older examples)
import * as pdfMake from 'pdfmake/build/pdfmake';
import * as pdfFonts from 'pdfmake/build/vfs_fonts';
(pdfMake as any).addVirtualFileSystem(pdfFonts);

Server (Node)

• Use the PdfPrinter constructor and point to real font file paths:
  import PdfPrinter from 'pdfmake';
  const printer = new PdfPrinter({
  Roboto: {
  normal: './fonts/Roboto-Regular.ttf',
  bold: './fonts/Roboto-Medium.ttf',
  italics: './fonts/Roboto-Italic.ttf',
  bolditalics: './fonts/Roboto-MediumItalic.ttf'
  }
  });

Notes

• For client-side custom fonts generate a vfs bundle (build-vfs.js) and include it (or use tools like pdfmake-font-generator).
• If using bundlers you may instead import 'pdfmake/build/vfs_fonts' (it will set pdfMake.vfs globally) — see docs for rollup/webpack caveats.

Verify font configuration timing and property access pattern.

The font configuration occurs after DataTable.Buttons.pdfMake(pdfmake) is called (line 42). Depending on how DataTables stores and uses the pdfMake reference, this timing might cause the fonts to be unavailable for PDF exports.

Additionally, the optional chaining pdfFonts.default?.vfs suggests uncertainty about the package structure. For pdfmake 0.2.18, verify:

1. The correct property path to access fonts (pdfFonts.vfs vs pdfFonts.pdfMake.vfs vs pdfFonts.default.vfs)
2. Whether fonts must be configured before or after passing pdfMake to DataTable.Buttons

🌐 Web query:

What is the correct way to configure pdfMake fonts with vfs_fonts in pdfmake version 0.2.18?

💡 Result:

Use the browser build and the build vfs file, then set pdfMake.vfs and register your font names. Example that works with pdfmake 0.2.18:

1. Imports

• ES/TS:
  import pdfMake from 'pdfmake/build/pdfmake';
  import pdfFonts from 'pdfmake/build/vfs_fonts';

2. Attach VFS and register fonts

• set the vfs (the vfs export is under pdfFonts.pdfMake.vfs) and add fonts (or use legacy pdfMake.fonts):
  (pdfMake as any).vfs = pdfFonts.pdfMake.vfs;
  pdfMake.addFonts?.({
  MyFont: {
  normal: 'MyFont-Regular.ttf',
  bold: 'MyFont-Bold.ttf',
  italics: 'MyFont-Italic.ttf',
  bolditalics: 'MyFont-BoldItalic.ttf'
  }
  });
  // or legacy:
  pdfMake.fonts = { /* same object as above */ };

3. Use the font in your docDefinition
   { defaultStyle: { font: 'MyFont' }, content: [ ... ] }

I need to verify the actual code structure in the repository before finalizing the review comment.

I found critical issues. Let me verify if these are the same or different pdfMake instances:

🏁 Script executed:

#!/bin/bash
# Check if pdfmake package default export and build/pdfmake are the same
# Search for any usage of the lowercase pdfmake vs camelCase pdfMake
rg -n "pdfmake\b|pdfMake\b" resources/js/app.js

🏁 Script executed:

#!/bin/bash
# Check pdfmake package structure - does the default export match build/pdfmake?
# This would help determine if line 9 and line 38 are the same object
