Releases: nibtime/next-safe-middleware
@next-safe/middleware@0.10.0
Minor Changes
-
#64
02ca36fThanks @nibtime! - feat: ✨ Hash-based CSP with trusted proxy loader to support Firefox and Safari (fixes #63)-
Avoids broken SRI validation of Firefox and Safari together with
strict-dynamic -
an important precursor for alternative configuration methods to middleware, that can't dynamically opt-out from
strict-dynamicby user agent
-
-
#64
02ca36fThanks @nibtime! - rebuild/refactor lib into many small modules with CSP manifest (fixes #40)-
writes out a single file to
.next/static/~csp/csp-manifest.jsonwith all information about trustable sources identified during SSR -
precursor for a multi-package approach to support alternative configuration methods (described in https://github.com/nibtime/next-safe-middleware/discussions/60#discussioncomment-3259782)
-
perf: fetch CSP manifest only once on first access and cache for all subsequent middlewares
-
-
#64
02ca36fThanks @nibtime! - feat(csp): newCspBuilderclass with fluent interface for safe and easy CSP construction + manipulation
@next-safe/middleware@0.9.0
Notes
-
Next 12.2 brought some significant changes to script insertion behavior / ISR that break the lib in certain cases with prior versions
-
All routes with
getServerSidePropshave to be wrapped withgsspWithNonceAppliedToCspfrom now on for Nonce-based CSP to work -
Only Next >= 12.2 is supported by this lib from now on
Minor Changes
-
#47
071f993Thanks @nibtime! - providegsspWithNonceAppliedToCspandgipWithNonceAppliedToCspwrappers to inject nonce into pages withgetServerSideProps/getInitialProps.BREAKING CHANGE: nonce doesn't get applied to CSP automatically anymore. This extra step is neccessary
as there is no longer a way of reliably do that with Next 12.2.BREAKING CHANGE: drop
enhanceAppWithNonce, it's no longer needed as nonce is injected thoughgetServerSidePropsof routes/pages now. That's actually a good thing, because customizingrenderPageis discouranged -
#47
f9ecbe3Thanks @nibtime! - 💥 changes toChainableMiddlewaredecrease resource utilization (fixes #45)- new
MiddlewareChainContextinterface
perf: decrease CPU utilization
- use
ctx.cache.getandctx.cache.setfor caching CSP in middleware chain (no serialize/deserialize) - write to repsonse only once from chain cache at the end
- remove unnecessary some double ops
perf: decrease deployed size
- use new built-in
userAgentfromnext/server
BREAKING CHANGE: supports only Stable middleware from now on (needs
next >= 12.2, as is specified in peerDeps)BREAKING CHANGE: replace
ua-parser-jswithuserAgentfromnext/serveravailable since12.2BREAKING CHANGE:
ChainableMiddlewarewith(ctx: MiddlewareChainContext)as 3rd parameter.BREAKING CHANGE: turn positional params into named params for
Configinitializer - new

f9ecbe3Thanks @nibtime! - fix(document): useanytype (children and return value) for components ofprovideComponents(fixes #46) -
#47
071f993Thanks @nibtime! - fix(document): support new script insertion behavior- handle
getPreloadDynamicChunksandgetPreloadMainLinksin<Head> - hash
beforeInteractiveInlineScriptsin<Head> - handle scripts also in drop-in component for
<NextScript> - trustify scripts in
initialProps.head
- handle

#47
071f993Thanks @nibtime! - fix(document): prevent application of nonce in production builds (fixes #49) -
#47
f9ecbe3Thanks @nibtime! - provide base logical operators for chain matchers (request predicates):matchNot,matchAnd,matchOr -
#47
071f993Thanks @nibtime! - fix(strictDynamic): exclude Safari from Hash-based Strict CSP- the problem is probably that Safari isn't truly CSP-3 compliant yet, like Firefox: https://bugzilla.mozilla.org/show_bug.cgi?id=1409200.
strict-dynamicseems to mess up SRI validation there.

071f993Thanks @nibtime! - fix: considerbasePathfromnext.config.jsfor writing and fetching hashes (fixes #48) -
#47
f9ecbe3Thanks @nibtime! - fix: betterisPageRequestmatcher- exclude only basepaths
/_nextand/api - exclude all paths with file endings
- exclude
isPreviewModeRequestandisNextJsDataRequest(new matchers)
- exclude only basepaths

#47
071f993Thanks @nibtime! - perf(middleware):telemetrywrapper to log basic measurements and infos from middleware execution -

#38
be1c950Thanks @nibtime! - Internal redesign for Next.js 12.2 (req.pagedeprecated) (#37) -
#38
be1c950Thanks @nibtime! - provide new middleware abstractions for Next.js 12.2 stable middlewarematchChainfunction that allows to disable chain execution for certain requests with a matcher (predicate onNextRequest)continuedfunction that allows to continue a middleware response to a middleware chainisPageRequestmatcher that matches only requests to Next.js pages
Patch Changes
@next-safe/middleware@0.7.0
Minor Changes
-
#36
2c8c5cdThanks @nibtime! - newcspmiddleware with extensive Typing for IntelliSense CSP configuration- typing has been borrowed from the SvelteKit CSP Integration, which is excellent
- handles annoying single quotes in the background, no need to think about them in code
-
#36
2c8c5cdThanks @nibtime! - versatilegetCspInitialPropsfor_document.js- flag to opt into styles trustification for CSP
- flag to opt out from script trustification for CSP
- option to pass external raw css text to hash for CSP. For instance needed for Mantine, to pass
extractCritical(initialProps.html).css(emotion) - option to enhance
<App>(_app.js) with nonce from SSR (needed for React Providers that can consume a nonce)
-
#36
2c8c5cdThanks @nibtime! - helper to set up CSP violation reprting to Sentry with a one-liner
Patch Changes
@next-safe/middleware@0.6.0
@next-safe/middleware@0.5.2
@next-safe/middleware@0.5.1
Patch Changes
-
#18
b40cc05Thanks @nibtime! - use correct call order inrender()of customDocumentcomponents. That should prevent things from breaking in ISR mode. -
#18
b40cc05Thanks @nibtime! - fetch script/style hashes for/404route if a request has no route/page. This makes strict CSP work with a custompages/404.js.
@next-safe/middleware@0.5.0
Minor Changes
-
#15
e7b4193Thanks @nibtime! - better bundling config + bundling of external utils. Saves around ~100% size for_middleware- important for edge where limit is 1MB -
#15
e7b4193Thanks @nibtime! - provide an API handler for easy creation of a report procesing endpoint by Next/Vercel cloud function -
#17
b084027Thanks @nibtime! - providestrictInlineStylesmiddleware. Extenddist/documentto write out hashes of inline styles (Hash-based) or attach nonce to inline styles (Nonce-based). -
#17
b084027Thanks @nibtime! - addtellsupportedconfig option (a function) tostrictDynamic. Allows for strong customization of fallback behavior by parsed user agent.
