docs(landing): add DevExtreme, ng2-file-upload and PrimeReact to the roundups; correct Prime licenses

[AminDhouib]

Why

Search Console (90 days to 2026-09-24) shows /angular/ ranking for competitor-component queries that the Angular roundup does not cover:

• "dx-file-uploader angular": 31 impressions, position 28.6 (DevExtreme's FileUploader, dx-file-uploader).
• "angular-file-uploader": 36 impressions, position 43. This is also the name of an npm package.
• "ngfileupload": the AngularJS-era ng-file-upload directive.
• On the React side, "primereact file upload" and "primereact fileupload" (3 impressions) land on /react/. The React roundup lists no PrimeReact, although the Vue and Angular roundups already cover PrimeVue and PrimeNG.

Since #457, /angular/ and /react/ link to their roundups, so the roundups are the right place for this content.

While checking licenses, I found that PrimeTek moved PrimeNG 22, PrimeReact 11 and PrimeVue 5 (all released 2026-07-15) from MIT to its PrimeUI License. The Angular and Vue roundups still called PrimeNG and PrimeVue MIT. The Vue roundup also called vue-upload-component MIT, but it is Apache-2.0.

What changed

All changes are inside apps/landing/content/docs/comparisons/. No pages are added, no FAQ questions are added (each roundup still has 5, so the FAQ_PAGES pin is unchanged), and every edited FAQ answer is changed identically in its faq: frontmatter a:. There are two commits:

1. 29a4c1aa docs(landing): add DevExtreme, ng2-file-upload and PrimeReact to the roundups
2. 306cfbb9 docs(landing): correct PrimeVue and vue-upload-component licenses in the Vue roundup

• best-angular-file-upload-libraries.mdx
  • Table rows, ### sections and "How to choose" bullets for ng2-file-upload and DevExtreme FileUploader. The table now has seven rows, and the intro says "seven".
  • PrimeNG's license cell and section now say it is MIT through v21 and under the PrimeUI License from v22.
  • A short "Older packages with similar names" section states the npm status of angular-file-uploader (no release since 7.1.1 in November 2021, which declares Angular 10) and ng-file-upload (an AngularJS 1.x directive, module ngFileUpload, last released November 2016).
  • FAQ "What is the best file upload library for Angular?" now names the DevExtreme and ng2-file-upload cases. "Are these libraries free?" changes from "Yes. All five are MIT-licensed." to "Most are." plus the per-library licenses.
  • A new "How to choose" bullet covers licensing.
  • The description is reworded to fit the new names inside 160 characters (157).
• best-react-file-upload-libraries.mdx: a table row, a ### PrimeReact FileUpload section, a "How to choose" bullet, a short-answer sentence, and "six" becomes "seven". FAQ "What is the best…" gains "Inside a PrimeReact app, PrimeReact FileUpload." and "Are these libraries free?" gains PrimeReact's license. The description is reworded (158 characters).
• best-vue-file-upload-libraries.mdx (second commit): the license cells, the PrimeVue section and "Are these libraries free?" now say that vue-upload-component is Apache-2.0 and that PrimeVue is MIT through v4 and under the PrimeUI License from v5. This page wasn't in the original scope, so the fix is a separate commit and can be dropped on its own.
• index.mdx (comparisons hub): the per-roundup library lists include the new entries.

Direct-to-S3, resumable and cloud-drive claims about upup are unchanged, and no page claims that server mode proxies uploads.

Sources checked

All sources were fetched from the build host on 2026-09-27 (UTC). The license table, the ng2-file-upload peer ranges, the two legacy packages' release dates and DevExtreme's 30-day trial were independently re-checked from a second machine before this PR was opened.

DevExtreme FileUploader

• License: npm view devextreme license gives SEE LICENSE IN README.md. The README links https://js.devexpress.com/Licensing, which says commercial apps need a 12-month subscription per developer, and a license-verification console message appears without a key.
• Wrapper: npm view devextreme-angular license peerDependencies gives MIT, with peers devextreme 26.1.5 and @angular/* >=20.0.0.
• EULA: https://js.devexpress.com/EULAs/DevExtremeComplete/. §1.1 says individuals also buy a subscription. §1.2 makes licensing per developer. §1.4 allows a 30-day evaluation only, and applications may not be created under it.
• Features: https://js.devexpress.com/Angular/Documentation/ApiReference/UI_Components/dxFileUploader/Configuration/. uploadMode is instantly/useButtons (Ajax) or useForm (HTML form). The page also documents uploadUrl, chunkSize ("Requires a server that can process file chunks"), uploadFile, uploadChunk, abortUpload, dropZone, and labelText for the built-in drop area. No resumable, S3 or cloud-drive option exists.
• Chunk merging: https://js.devexpress.com/Angular/Documentation/Guide/UI_Components/FileUploader/Upload_Files/Client-Side_Settings/ says the server merges chunks, with ASP.NET and PHP server examples.
• Examples: https://github.com/DevExpress-Examples/devextreme-file-uploader-direct-upload-to-amazon and …-direct-upload-to-azure both build on uploadChunk. The Amazon example's Angular code POSTs each chunk to an ASP.NET endpoint (amazon.gateway.ts, uploadPart), so the page doesn't call it direct-to-S3. It only says the examples implement S3 and Azure Blob uploads with uploadChunk.

ng2-file-upload

• Package: npm view ng2-file-upload dist-tags license maintainers repository.url gives latest 9.0.0 (published 2025-09-04, peer @angular/core ^20.0.0) and next 10.0.0 (published 2026-03-05, peer ^21.x.x). The license is MIT, and the repo is valor-software/ng2-file-upload.
• One Angular major per version: npm view ng2-file-upload@<v> peerDependencies gives 3.0.0 → Angular 14, 4 → 15, 5 → 16, 6 → 17, 7 → 18, 8 → 19. 1.x declares * and 2.x declares 11 or 12, which is why the page says "since 3.0.0".
• npm pack ng2-file-upload@9.0.0, index.d.ts:
  • FileUploaderOptions has url, method, headers, allowedMimeType, allowedFileType, maxFileSize, queueLimit, disableMultipart and more.
  • FileItem has a per-item url and progress.
• Same tarball, fesm2022/ng2-file-upload.mjs: uploads go through new XMLHttpRequest(). The directives use the selectors [ng2FileSelect] and [ng2FileDrop]. There is no chunk or resume code; the only match for "chunks" splits file extensions.
• README: disableMultipart "Some APIs (e.g. Amazon S3) may expect the file to be streamed rather than sent via a form."
• GitHub API repos/valor-software/ng2-file-upload: not archived, MIT, last push 2026-03-05.

angular-file-uploader and ng-file-upload

• npm view angular-file-uploader time peerDependencies: last release 7.1.1 on 2021-11-05, peer @angular/core ^10.0.5, not deprecated.
• npm view ng-file-upload version time description: 12.2.13 on 2016-11-05, described as "An AngularJS directive for file upload…". Its tarball dist/ng-file-upload.js declares angular.module('ngFileUpload'.
• npm view angular deprecated: "AngularJS support has officially ended."

PrimeReact, PrimeNG and PrimeVue

• npm view <pkg>@<v> license for the last MIT release and the first PrimeUI release of each:

  Last MIT release	First PrimeUI release
  primereact@10.9.9	primereact@11.0.0 (2026-07-15)
  primevue@4.5.5	primevue@5.0.0 (2026-07-15)
  primeng@21.1.10	primeng@22.0.0 (2026-07-15)

  All three MIT releases report MIT, except PrimeNG 21, whose LICENSE.md makes community versions MIT and -lts versions commercial. All three PrimeUI releases report SEE LICENSE IN LICENSE.md.

• LICENSE.md in primereact@11.1.0, primeng@22.1.1 and primevue@5.0.1 is the "PrimeUI License": a free Community License or a paid Commercial License, and "A valid license key is required to use this software."

• https://primeui.dev/licenses/community (updated 2026-08-26): individuals qualify, and so do organizations with fewer than 5 developers and 10 employees, under $1M revenue and $3M outside capital, and outside the public and education sectors. It also says: "the MIT-licensed versions of our libraries (PrimeNG 21, PrimeVue 4, PrimeReact 10, and earlier)".

• PrimeReact 11 FileUpload (https://primereact.dev/docs/styled/components/fileupload):

  • drag and drop, multiple files, auto, progress, accept/maxFileSize validation and url;
  • customUpload with uploadHandler;
  • composable parts (FileUpload.Root, FileUpload.Trigger, …) and a headless useFileUpload hook.

• PrimeReact 10 FileUpload (https://v10.primereact.org/fileupload/): basic and advanced modes, plus customUpload with uploadHandler.

• https://primeng.dev/fileupload (22.1.1) and https://primevue.dev/fileupload/ (5.0.1) still document basic and advanced uploads and customUpload with a custom handler. The existing PrimeNG and PrimeVue descriptions hold.

vue-upload-component

• npm view vue-upload-component license gives Apache-2.0, and the GitHub API repos/lian-yue/vue-upload-component reports license Apache-2.0.

Other licenses named in the edited "free?" answers

• npm view <pkg> license gives MIT for ngx-file-drop, filepond, angular-filepond, react-filepond, vue-filepond, @uppy/core, @uppy/angular, react-dropzone, @rpldy/uploady, uploadthing and @uploadthing/react.

Left out on purpose

• DevExtreme's price. The Buy page lists DevExtreme Complete at $899.99 per developer, but prices change, so the page says only "paid per-developer license".
• The PrimeUI eligibility fine print. LICENSE.md and primeui.dev disagree on non-profits and open-source projects, so the pages state only what both agree on: free for individuals and eligible small organizations, paid otherwise.
• Any claim that DevExtreme uploads directly to S3 or Azure (see the example note above).
