Replace the webpack+acorn transform with a Babel plugin This commit converts the pdfjsdev-loader transform into a Babel plugin, to skip a AST->string->AST round-trip. Before this commit, the webpack build process was: 1. Babel parses the code 2. Babel transforms the AST 3. Babel generates the code 4. Acorn parses the code 5. pdfjsdev-loader transforms the AST 6. @javascript-obfuscator/escodegen generates the code 7. Webpack parses the file 8. Webpack concatenates the files After this commit, it is reduced to: 1. Babel parses the code 2. Babel transforms the AST 3. babel-plugin-pdfjs-preprocessor transforms the AST 4. Babel generates the code 5. Webpack parses the file 6. Webpack concatenates the files This change improves the build time by ~25% (tested on MacBook Air M2): - `gulp lib`: 3.4s to 2.6s - `gulp dist`: 36s to 29s - `gulp generic`: 5.5s to 4.0s - `gulp mozcentral`: 4.7s to 3.2s The new Babel plugin doesn't support the `saveComments` option of pdfjsdev-loader, and it just always discards comments. Even though pdfjsdev-loader supported multiple values for that option, it was effectively ignored due to `acorn` dropping comments by default. 2024-01-22 18:33:31 +01:00			`import { Test } from "import-name";`
Removes last UMDs from the modules. 2017-05-30 20:38:22 -05:00			`import { Test2 } from './non-alias';`

[api-minor] Attempt to improve support for using the PDF.js builds with Vite Similar to Webpack there's apparently other bundlers that will not leave `import`-calls alone unless magic comments are used. Hence we extend the builder to also append `/* @vite-ignore /` comments to `import`-calls, in order to attempt to improve support for using the PDF.js builds together with Vite. This patch also renames `__non_webpack_import__` to `__raw_import__` since the functionality is no longer bundler-specific. PLEASE NOTE:* This patch is provided as-is, and it does not mean that the PDF.js project can/will provide official support for Vite. 2025-03-27 21:31:27 +01:00			`await import(`
