Las tags duplicadas crean claves duplicadas en Tags.
Las tags son texto libre separado por comas. Un gestor puede escribir la misma tag dos veces, por ejemplo "ia, ia". En ese caso, key={tag} produce dos claves iguales. React emite un aviso por la clave duplicada y puede reconciliar mal esos elementos. Además, una tag vacía se muestra como # sin texto.
Elimina los duplicados y las tags vacías antes de aplicar slice. Así tag sirve como clave única sin usar el índice.
Corrección propuesta
function Tags({ tags }: { tags: string[] }) {
- if (tags.length === 0) return null;
+ const visible = [...new Set(tags.map((t) => t.trim()).filter(Boolean))].slice(0, 3);
+ if (visible.length === 0) return null;
return (
<ul className="flex flex-wrap gap-x-3 gap-y-1 font-mono text-[11px] uppercase tracking-[0.15em] text-white/40">
- {tags.slice(0, 3).map((tag) => (
+ {visible.map((tag) => (
<li key={tag}>#{tag}</li>
))}
</ul>
);
}Según los learnings: "Avoid using array indices or non-unique fields (like a label) as keys".

<excerpt># 1b10b13 fix(next): reject protocol-relative URLs in image optimization (`#65752`) - SHA: 1b10b13a7486d223df87d82e93b75eac2e8ed65a - Repository: vercel/next.js - Author: emmerich - Date: 2024-05-15T22:21:08Z - +6 -1 in 2 files --- fix(next): reject protocol-relative URLs in image optimization (`#65752`) This PR introduces a **breaking change** that returns a 400 error if the Image Optimization API is given a protocol-relative URL. The Image Optimization API currently checks whether the given image URL is relative by checking `url.startsWith(&`#39`;/&`#39`;)`. This means that protocol-relative URLs, such as `//example.com`, pass the check and are treated as relative. They in turn skip any kind of validation provided when matching against `remotePatterns` and are passed back to the optimation logic as a relative URL. My knowledge of the stack stops there, but in our case at GitBook it led to a nasty attack where non-GitBook content could be served over this URL: https://docs.gitbook.com/_next/image?url=//example.com&w=1200&q=100 - even though we have configured `remotePatterns` to protect against it. I originally went into the problem wanting to handle the URL properly (treating it as an absolute URL and potentially using the protocol of the Optimization API itself as the relative protocol), but after seeing the code in https://github.com/vercel/next.js/blob/canary/packages/next/src/client/legacy/image.tsx#L135 and https://github.com/vercel/next.js/blob/canary/packages/next/src/shared/lib/image-loader.ts#L26 it feels that protocol-relative URLs are just not really supported anywhere. My understanding is that very few uses of `next/image` will be allowed to use protocol-relative URLs, so the impact of this breaking change should be quite low? If others disagree I am happy to modify and to use the protocol of the request as a stand-in for the relative protocol. --------- Co-authored-by: Steven <steven@ceriously.com> ## Changed Files | File | Status | + | - | | --- | --- | --- | --- | | test/integration/image-optimizer/app/pages/api/no-header.js | added | 5 | 0 | | test/integration/image-optimizer/test/util.ts | modified | 1 | 1 |</excerpt>

<excerpt># Pull Request: vercel/next.js `#72100` - Repository: vercel/next.js | The React Framework | 138K stars | JavaScript ## Fix checking for protocol relative URLs in image optimization when parameter starts with encoded slashes - Author: [`@jpreynat`](https://github.com/jpreynat) - State: closed - Labels: type: next, locked, tests - Source branch: fix-image-url-check - Target branch: canary - Mergeable: unstable - Commits: 6 - Additions: 26 - Deletions: 0 - Changed files: 2 - Created: 2024-10-30T18:32:51Z - Updated: 2024-11-29T00:05:48Z - Closed: 2024-11-13T10:21:59Z ### What? This PR improves the security of the `_next/image` endpoint by making sure that url parameters starting with multiple escaped slashes are properly detected as protocol relative ones. ### Why? For some reason, the `new URL()` constructor behaves very strangely with this, as it can accept any number of forward slashes and backslashes, and it will still consider the URL as protocol relative, discarding any hostname passed as second argument. So except for `new URL(&`#39`;\\example.com&`#39`;, &`#39`;https://n&`#39`;)`, that properly returns `&`#39`;https://n/example.com&`#39`;`, all of these: - `new URL(&`#39`;\//example.com&`#39`;, &`#39`;https://n&`#39`;)` - `new URL(&`#39`;/\//example.com&`#39`;, &`#39`;https://n&`#39`;)` - `new URL(&`#39`;/\\example.com&`#39`;, &`#39`;https://n&`#39`;)` - `new URL(&`#39`;/\\/example.com&`#39`;, &`#39`;https://n&`#39`;)` - `new URL(&`#39`;/\\/\/\/\/example.com&`#39`;, &`#39`;https://n&`#39`;)` will actually return `&`#39`;https://example.com/&`#39`;`. ### How? To prevent this from happening, this PR transforms all consecutive slashes and backslashes, when there are more than 2, into `//` when we check if the `url` starts by `//`, a protocol relative URL. --- ### Timeline **Johan Preynat** pushed commit `adc1e3b`: Add tests · Oct 30, 2024 at 6:11pm **Johan Preynat** pushed commit `d576ce8`: Add fix · Oct 30, 2024 at 6:12pm **ijjk** added label `tests` · Oct 30, 2024 at 6:32pm **ijjk** added label `type: next` · Oct 30, 2024 at 6:32pm **`@ijjk`** commented · Oct 30, 2024 at 6:33pm · edited > Allow CI Workflow Run > > - [ ] approve CI run for commit: e3f18980eb3cf7b366f3fa85132a9b4118ce8a1b > > Note: this should only be enabled once the PR is ready to go and can only be enabled by a maintainer **Johan Preynat** pushed commit `bab8244`: Merge branch &`#39`;canary&`#39`; into fix-image-url-check · Oct 30, 2024 at 6:35pm **`@timneutkens`** commented · Nov 1, 2024 at 12:48pm > **Review (changes requested):** > After having a quick look I don&`#39`;t think we should change the url handling.

<excerpt># d9ce336 fix(next): reject protocol-relative URLs in image optimization (`#65752`) - SHA: d9ce336a13b84e52980dee31ef8c68316242d403 - Repository: vercel/next.js - Author: emmerich - Date: 2024-05-15T22:21:08Z - +21 -1 in 3 files - Verified: yes --- fix(next): reject protocol-relative URLs in image optimization (`#65752`) This PR introduces a **breaking change** that returns a 400 error if the Image Optimization API is given a protocol-relative URL. The Image Optimization API currently checks whether the given image URL is relative by checking `url.startsWith(&`#39`;/&`#39`;)`. This means that protocol-relative URLs, such as `//example.com`, pass the check and are treated as relative. They in turn skip any kind of validation provided when matching against `remotePatterns` and are passed back to the optimation logic as a relative URL. My knowledge of the stack stops there, but in our case at GitBook it led to a nasty attack where non-GitBook content could be served over this URL: https://docs.gitbook.com/_next/image?url=//example.com&w=1200&q=100 - even though we have configured `remotePatterns` to protect against it. I originally went into the problem wanting to handle the URL properly (treating it as an absolute URL and potentially using the protocol of the Optimization API itself as the relative protocol), but after seeing the code in https://github.com/vercel/next.js/blob/canary/packages/next/src/client/legacy/image.tsx#L135 and https://github.com/vercel/next.js/blob/canary/packages/next/src/shared/lib/image-loader.ts#L26 it feels that protocol-relative URLs are just not really supported anywhere. My understanding is that very few uses of `next/image` will be allowed to use protocol-relative URLs, so the impact of this breaking change should be quite low? If others disagree I am happy to modify and to use the protocol of the request as a stand-in for the relative protocol. --------- Co-authored-by: Steven <steven@ceriously.com> ## Changed Files | File | Status | + | - | | --- | --- | --- | --- | | packages/next/src/server/image-optimizer.ts | modified | 6 | 0 | | test/integration/image-optimizer/app/pages/api/no-header.js | added | 5 | 0 | | test/integration/image-optimizer/test/util.ts | modified | 10 | 1 |</excerpt>

<title>Image component fails with leading double slash (protocol-relative URLs)</title>
<location>GitHub issue 18536 in vercel/next.js (link omitted to avoid creating a cross-reference)</location>
<excerpt># Image component fails with leading double slash (protocol-relative URLs) - State: closed - Author: daneden - Created: 2020-10-30T13:04:04Z - Updated: 2022-01-29T07:05:36Z - Repository: vercel/next.js - Number: `#18536` - Assignees: styfle, Timer --- Out of curiosity, I was browsing the image optimiser code that landed in Next.js 10 (congrats and thank you!) when I noticed a potential bug in the `isAbsolute` condition branch: https://github.com/vercel/next.js/blob/426331883638911dec6f93517d6b5406abac1d97/packages/next/next-server/server/image-optimizer.ts#L67 This assumes that protocol-relative URLs won&`#39`;t be passed to the optimiser, for example `//url.com/image.jpg` will request `https` when the caller is on `https`, and `http` when the caller is on `http`. This might be an edge case, but consider any folks migrating from their current `img` tags to the `next/image` component and using protocol-relative URLs; they&`#39`;ll encounter a bug where `next-server/image-optimizer` treats the URL as a file path. An alternative would be to test a regex pattern for URLs: ```ts if (!/^(https?:)?\/\//.test(url)) { // Relative URL/path } else { // Absolute URL/path } ``` ## Timeline - francofantini subscribed **JamesSingleton** commented on 2020-10-31T03:53:12Z: > I ran into this issue using Contentful where the URL looks like: `//images.ctfassets.net/` from their API. This causes the image to become `/_next/image?url=%2F%2Fimages.ctfassets.net%2F` and causes a broken image. This is the error in the terminal > ``` > [Error: Input buffer contains unsupported image format] > ``` - Timer added label "kind: bug" - Timer milestoned - Timer demilestoned - Timer milestoned - Timer demilestoned - Timer milestoned - styfle was assigned - Timer was assigned - Referenced by issue `#18573`: Image component caching image **styfle** commented on 2020-10-31T21:59:10Z: > Thanks, we can probably detect leading double slash and print a better error. > > The reason we can&`#39`;t use that URL as-is because we don&`#39`;t know the intended protocol/scheme. Many users run Next.js as HTTP but put a HTTPS proxy in front. > > That&`#39`;s why we used the leading `/` to detect internal vs external URLs. > > We _might_ decide to convert leading `//` to `https://` but this will lead to a cache miss if one image src is `//` and another src is `https://` referencing the same image. - Renamed from "Possible Bug in `next-server/image-optimizer`" to "Image component fails with leading double slash (protocol-relative URLs)" - styfle added label "point: 2" - Referenced by PR `#18809`: Print error when Image src is protocol-relative - kodiakhq[bot] closed - Referenced in commit 80fd3d5 - Referenced in commit e7760f3 - Referenced by issue `#18977`: Images from CDN not prefixed with http(s) are considered unsupported format - Referenced by issue `#18918`: `next/image` interprets protocol-agnostic `src` prop as relative path **balazsorban44** commented on 2022-01-29T07:05:35Z: > This issue has been automatically locked due to no recent activity.

Excluye las URL relativas al protocolo antes de usar next/image.
hero_image llega sin normalizar desde la base de datos. Por tanto, //cdn.example/cover.jpg satisface startsWith("/") y evita el fallback ProjectCover. En Next.js 15.5.25, el loader de desarrollo lanza un error para esta entrada. En producción genera la URL de optimización, pero la API de imágenes responde con 400.

Rediseña los segmentos de noticias/eventos y de proyectos del landing tomando como referencia una composición de dos columnas con tarjetas de portada visual, conteo total y CTA discreto. Los dos segmentos quedan deliberadamente distintos entre sí: proyectos es visual y orientado a imagen, noticias es editorial y orientado a texto.
Ramas:
feature/landing-updates-projects-redesign→devProyectos (
ProjectsPreviewSection)Important
La versión anterior mostraba tarjetas sin imagen, con badges de etapa multicolor y resúmenes largos. Todas tenían el mismo peso visual y no había un ancla narrativa. Además,
STAGE_LABELS/STAGE_COLORSse importaban desdehooks/useProjects, un módulo"use client", dentro de un Server Component. Eso es frágil porque esas constantes llegan como referencias de cliente.components/landing/ProjectsPreviewSection.tsx. Layout 4/8 columnas. A la izquierda va la tesis ("Innovación con propósito. Tecnología con impacto.") con un punto de acento. A la derecha vanTotal: N proyectos, tres tarjetas compactas (portada 4:3, título y máximo dos chips#área) y el CTA "Ver todos los proyectos →" en monoespaciada. La etapa pasa a una pastilla monocroma sobre la portada. La tarjeta completa es el link y tienefocus-visible. Se agregaid="proyectos", que el quick-nav del hero ya enlazaba sin destino. También se agrega un estado vacío.components/landing/ProjectCover.tsx(nuevo). Genera en servidor una portada SVG determinista a partir del slug, con cuatro variantes (anillos, ondas, retícula de puntos, hexágonos) sobre un glow rojo. Todos los seeders tienenhero_image: null, así que sin esto las tarjetas quedarían vacías. SiheroImagees una ruta local se usanext/image; la decisión queda documentada con[DECISION]en el código.Noticias y eventos (
EventsSection)Note
Antes, una imagen decorativa de 720px con
prioritycompetía con el contenido y cada tarjeta tenía un borde de color distinto. El CTA quedaba escondido dentro de la última tarjeta.components/landing/EventsSection.tsx. Cabecera horizontal con eyebrow "Bitácora del semillero", título y CTA a la derecha, invirtiendo la composición de proyectos. La primera noticia se muestra como destacada (título grande, descripción y botón circular). Las dos siguientes se muestran como un índice numerado02,03con fecha en monoespaciada.border_colorse conserva como una línea superior o un punto de acento y se valida como hex, con el color link del tema como respaldo. Se agregan<time dateTime>y un estado vacío. Se elimina la imagencyberpunkWoman.webpde esta sección; el asset queda enpublic/.app/page.tsx.
