Errors when using webpack/Typescript #72
Description
I hit 2 errors in my project where we use webpack/Typescript.
(Note: I'm using the library in a web page)
The first error happened when building my project,
ERROR in ./~/pptxgenjs/dist/pptxgen.js
Module not found: Error: Cannot resolve module 'fs' in c:\myproj\node_modules\pptxgenjs\dist
@ ./~/pptxgenjs/dist/pptxgen.js 2536:10-23
ERROR in ./~/image-size/lib/index.js
Module not found: Error: Cannot resolve module 'fs' in c:\myproj\node_modules\image-size\lib
@ ./~/image-size/lib/index.js 3:9-22
ERROR in ./~/image-size/lib/types/tiff.js
Module not found: Error: Cannot resolve module 'fs' in c:\myproj\node_modules\image-size\lib\types
@ ./~/image-size/lib/types/tiff.js 6:9-22
By referring to this post, I put the workaround in my webpack config
node: { fs: "empty" }
Then I hit another error when running my page in browser
Uncaught (in promise) TypeError: callback is not a function at eval (eval at <anonymous> (main.js:8466), <anonymous>:193:104)
It comes from this line of code in pptxgen.js
zip.generateAsync({type:'nodebuffer'}).then(function(content){ fs.writeFile(strExportName, content, callback(strExportName)); });
So, I comment it out as the following to bypass the error
/*
if ( NODEJS ) {
zip.generateAsync({type:'nodebuffer'}).then(function(content){ fs.writeFile(strExportName, content, callback(strExportName)); });
}
else { */
zip.generateAsync({type:'blob'}).then(function(content){ writeFileToBrowser(strExportName, content, callback); });
// }
Is there any way I can resolve the second error without changing PptxGenJS code?
