I'm working with bwip-js
in my React TypeScript application and I'm encountering a problem with the toCanvas
method. When I try to use it, I receive the error: Property 'toCanvas' does not exist on type 'typeof BwipJs'
.
Upon inspecting the bwip-js
type in VS Code, it appears to be importing the Node module type instead of the browser module type. The package.json can be found here: bwip-js package.json
In an attempt to resolve this, I tried to directly import the browser module type with the following line: import BwipJs from "bwip-js/dist/bwip-js.js";
. VS Code seems to be fine with this and it recognizes the toCanvas
method. However, when I run the application, I'm presented with a new error:
Module not found: Error: Package path ./dist/bwip-js.js is not exported from package \node_modules\bwip-js (see exports field in \node_modules\bwip-js\package.json)
Does anyone have any insights on how I can successfully use the toCanvas
method from bwip-js
in a browser environment within a React TypeScript application? Any help would be greatly appreciated.
