Is it true that SPFx doesn't support JQuery?

Currently, I am in the process of developing a new SharePoint Web Part using SPFx generated by Yeoman. The scaffolding template is working well and I have encountered no issues adding NPMs for JQuery and JQueryUI. As I run GULP SERVE, everything seems to be running smoothly without any errors.

However, trouble arises when I include the following line in my JQWebPart.ts file:

      import * as jQuery from 'jquery';

Upon adding the above line, GULP SERVE spews out a long list of errors. Here are the last few lines of the error log:

[16:54:06] Error - typescript - node_modules\@types\jquery\index.d.ts(7502,33): error TS2314: Generic type 'Callbacks<T, Function>' requires 2 type argument(s).
[16:54:06] Error - typescript - node_modules\@types\jquery\index.d.ts(7517,32): error TS2314: Generic type 'PlainObject<T, any>' requires 2 type argument(s).
[16:54:06] Finished subtask 'tslint' after 3.95 s
[16:54:06] Error - 'typescript' sub task errored after 3.95 s
 "TypeScript error(s) occurred."

I am quite perplexed about the issues that arise in my Web Part when incorporating JQuery. If anyone has any insights or suggestions, please feel free to share!

Answer №1

Many thanks to Rohit Waghela for providing a solution to address JQuery issues in SPFx that is already available:

Visit this link for more information.

The main issue at hand is the compatibility problems between TypeScript and JQuery. The key steps to resolve this are as follows:

1) Remove JQuery dependency: npm uninstall @types/jquery

2) Install a compatible version: 

npm install @types/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="dfb5aeaabaada69fedf1eff1ebe7">[email protected]</a> --save-dev
