Updates i18next from 26.4.0 to 26.5.6

Release notes

Sourced from i18next's releases.

v26.5.6

  • fix: cloneInstance({ forkResourceStore: true }) now copies the resources at every level. It copied them only down to the namespace objects, so nested keys and arrays stayed shared with the original instance: addResource() with a nested key (fork.addResource('en', 'translation', 'greeting.hello', 'Hi')) or a deep addResourceBundle() on the fork also changed the original instance and every other fork. Flat keys were already isolated. Forking a large store takes a bit longer: with 300k keys in nested groups, about 11 ms instead of 3 ms per fork. Clones without forkResourceStore still share the store as before. Thanks @​nk-batman21 (#2456, follow-up to #2270).

v26.5.5

  • fix: with the default skipOnVariables: true, a {{placeholder}} inside a value inserted with an unescaped {{- var}} now stays literal, as it already did for {{var}}. The escape pass ran after the unescaped values were written and scanned them again, so t('{{- a}}', { a: '{{b}}', b: 'c' }) returned 'c' instead of '{{b}}'. With pre-built HTML that carries user text, like t('You may contact {{name}} at {{- emailHTML}}.', { name, emailHTML }), that text could pull another variable of the same t() call into the output. Results with skipOnVariables: false, and values without placeholders, are unchanged. Compatibility note: a {{- var}} value whose placeholders were meant to be filled from the same t() call now keeps them literally; skipOnVariables: false restores the old behavior. Thanks @​nk-batman21 (#2455, reported in #1595).

v26.5.4

  • fix: with the default skipOnVariables: true, a {{placeholder}} inside an interpolated value now stays literal also when the same placeholder appears later in the translation. Each value was written with String.replace, which replaces the first copy of the placeholder text, and that could be the copy inside an earlier value: t('{{name}} has {{count}} items', { name: '{{count}}', count: 5 }) returned '5 has {{count}} items' instead of '{{count}} has 5 items'. The value is now written at the position of the matched placeholder. Results with skipOnVariables: false are unchanged. Thanks @​nk-batman21 (#2454, reported in #1595).
  • fix: with useRawValueToEscape: true, a non-string value in an unescaped {{- var}} placeholder or with escapeValue: false no longer throws val.replace is not a function; it is converted to a string like any other value.

v26.5.3

  • fix(types): with the selector API, a plural key now requires count also when the call passes an explicit ns. t(($) => $.item) already failed without count, but t(($) => $.item, { ns: 'items' }) compiled, although at runtime it looks up item instead of item_one / item_other and returns the key. It now fails the same way, also with ordinal: true, defaultValue, an ns array, a key prefix and i18n.t. Calls with count, context, returnObjects: true and arrays of selectors, as well as return types, are unchanged. Thanks @​nyarthan (#2452).

v26.5.2

  • fix(types): on TypeScript 7, a t() call with a missing, misspelled or wrongly typed option now reports that option again (Property 'album' is missing, Type 'string' is not assignable to type 'number'), as TypeScript 5 and 6 do. TypeScript 7 elaborated the error against the default-value signature instead and ended in '{ count: 3; albm: "Summer"; }' is not assignable to type 'string': on a failed call TypeScript explains the last of the equally matching signatures, and TypeScript 7 sorts the 3-element [key, defaultValue, options?] last. It is now written as two signatures, [key, defaultValue] and [key, defaultValue, options]. This affects the default key checks with i18next {{name}} messages as well as parseInterpolation: 'icu' and 'mf2'. Which calls compile, their return types and the error positions are unchanged on TypeScript 5.9, 6 and 7.

v26.5.1

  • perf(types): type-checking t() calls against a large namespace is no longer quadratic in the number of keys. TypeScript does not cache keyof of an object type, and the types rebuilt the union of all keys of a namespace once per key while building the key union, and again in every t() call to look up the return type. Both now use a cached key union, and a literal key is looked up directly instead of being intersected with every key. With 5,000 keys in one namespace and one call per key, the check time went from 14.8s to 1.1s (TypeScript 6); with 1,000 keys from 0.75s to 0.27s. Keys, return types and errors are unchanged.
  • perf(types): the selector API (enableSelector: true / 'strict') with context is no longer quadratic in the size of an object. To decide which keys a context keeps, the types scanned all keys of the object once for every key, also when TypeScript checks the selector with context widened to string. With 1,000 keys plus one context variant each, a namespace took 18.7s and failed with "Type instantiation is excessively deep and possibly infinite" (TS2589); 2,500 and more ran out of memory. The context variants of an object are now collected once, in one pass over its keys: 1,000 keys check in 0.69s, 5,000 in 3.1s. Long keys (whole sentences with keySeparator: false) work as before. Selected values and errors are unchanged.

v26.5.0

  • feat(types): parseInterpolation: 'icu' and parseInterpolation: 'mf2' type t() options from the message's ICU MessageFormat arguments (i18next-icu) or MessageFormat 2 variables (i18next-mf2), so ICU and MF2 users no longer need parseInterpolation: false and lose argument checking. Missing, misspelled and wrongly typed arguments fail, and so does leaving out the options for a message with arguments (t('greeting')); that error names the missing arguments. Opt-in, default true is unchanged.
    • ICU: {name} takes string | number, {n, number}, plural and selectordinal take number, {d, date} and {t, time} take Date, select takes its case keys or any string (for other), and arguments nested in cases are required too. # and tags are not arguments, apostrophe quoting is read like intl-messageformat does.
    • MF2: {$name} takes string | number, a variable annotated with :number, :integer, :currency, :percent or :unit (inline or through .input / .local) takes number, :datetime, :date and :time take Date, :string takes string, option and markup variables (minimumFractionDigits=$digits, {#link href=$url}) are required too, .local variables are not arguments, and |quoted literals| and \{ escapes are skipped.
    • interpolationFormatTypeMap overrides a type by ICU format or MF2 function name, e.g. date: Date | number or a custom uppercase: string.
    • Applies to t(), getFixedT(), i18n.t, key prefixes, namespaces, the selector API and react-i18next's Trans values. Messages need literal types, as the resources file from i18next-cli's types command has them.
    • Type-check cost with 1,000 messages and one call each: 1.35s instead of 0.86s with false (TypeScript 6), 0.5s instead of 0.26s with TypeScript 7. Messages that no call uses cost nothing.
  • fix(types): with the default (non-strict) key checks, an options object with a missing or misspelled interpolation variable now reports the missing variable (Property 'name' is missing) instead of '{ nmae: string }' is not assignable to type 'string' from the default-value overload.

v26.4.7

  • perf: cloneInstance() no longer inherits preload. loadResources() adds every preload language to each load, and clones copied preload from the parent, so a clone's init() and every changeLanguage() walked all preloaded languages × all namespaces through queueLoad() / hasResourceBundle(), although the parent had already loaded them into the shared store. With i18next-http-middleware (one clone + changeLanguage() per request), 25 preloaded languages and 20 namespaces, that was most of the per-request CPU: the reproduction from the issue went from ~90 µs to ~10 µs per request, the same as with a single language. A clone now only loads what it uses itself: its changeLanguage() no longer waits for parent preload languages that are still loading (the parent's own init() still does), and clone.loadNamespaces() loads the new namespace for the clone's language and fallbacks instead of every preloaded language. clone.loadLanguages() works as before, the parent instance is unchanged, and passing preload to cloneInstance() keeps the old behavior. Thanks @​theMostCuriousHomunculus for the detailed report (#2451).

v26.4.6

  • fix: a fallback language whose formatted code is already in the hierarchy is no longer added a second time. toResolveHierarchy() checked the raw fallbackLng value against the list, but the list holds formatted codes, so any fallback written differently from its formatted form slipped through: lng: 'de-CH' with fallbackLng: 'de-ch' gave languages ['de-CH', 'de', 'de-CH'], and the same happened with fallbackLng: 'EN' + cleanCode, lowerCaseLng, and Intl aliases (iw-IL → he-IL). Missing keys were looked up in the same language twice. Only exact duplicates are removed; the order is unchanged. Thanks @​lprnmns (#2450).

v26.4.5

  • fix: hasLoadedNamespace(ns, { lng }) no longer stays false forever when the passed in lng is loaded under another code, or not at all. It checked the load state of the raw lng, but loadLanguages() stores a language under its resolved code (de-ch → de-CH, de-CH → de with load: 'languageOnly') and skips a lng outside supportedLngs entirely (only the fallback gets loaded), so that state never got set. react-i18next's useTranslation(ns, { lng }) then never became ready: with useSuspense it kept throwing an already resolved promise and React retried forever (100% CPU, SSR never finished), without it the load effect re-rendered in a loop. It now checks the code the language is actually loaded under, and for a lng outside supportedLngs only waits for the fallback, which is also what t() resolves to. Calls without lng and the precheck (react-i18next's bindI18n: 'languageChanging') are unchanged (react-i18next#1934).

v26.4.4

  • fix(security): the nesting regexp no longer backtracks exponentially (ReDoS) on an unclosed $t(. Its repeated group had overlapping alternatives ([^()"']+ inside (?:...)*?, and inside parentheses [^()] also matched quotes), so a string containing $t( without a closing ) made the engine try every way to split the text: about 2x the runtime per extra character, and a ~25 character value hung t() for minutes. With the default config this was reachable through any interpolated value (t('greet', { name: '$t(aaaaaaaaaaaaaaaaaaaaaaaa' })): escaping does not touch $, t or (, and the skipOnVariables check runs the regexp on the interpolated result, so nest: false did not help either. Every alternative now starts with a different character (plain char, ", ' or (), so there is only one way to match and the cost is linear. Quoted strings and one level of parentheses in nesting options keep working (#2336). The only difference: a lone " or ' inside unquoted parentheses within $t(...) is no longer matched. Affects 25.3.3 to 26.4.3. Thanks to Anisetti Chaitanya Eshwar Prasad for the responsible disclosure.
  • fix(security): nest() now resolves $t(...) in a single pass and no longer nests text that came out of a resolved value. Every nested lookup reset the shared nesting regexp, so the loop started over from the beginning of the string after each match. That had two effects. First, a $t(...) inside a variable that the nested lookup deliberately kept literal (default skipOnVariables: true) was resolved anyway by the outer loop: with outer: 'A $t(inner) B' and inner: 'Hi {{name}}', t('outer', { name: '$t(secret)' }) rendered the secret translation. It now stays A Hi $t(secret) B, the same as without the outer nesting; with skipOnVariables: false it is still resolved. Second, the cost was quadratic when an unclosed $t( preceded many nestings, which matters when an app passes untrusted input as the key itself (t(userInput)): 20,000 nestings took ~1.4 s, now ~25 ms. The resolved value is now sliced into the result instead of going through String.replace, so $&, $`, $' and $$ stay literal as before (26.4.2).

v26.4.3

  • perf: ResourceStore.hasLanguageSomeTranslations() no longer enumerates every key of a large bundle on each call. It ran Object.keys() on the whole bundle just to learn whether it had at least one key, and init() / changeLanguage() reach it three times per instance (once while picking the language, twice via setResolvedLanguage()). With large flat bundles and one i18next instance per SSR request reusing the same resources, that showed up as measurable CPU work before any t() call. Bundle objects already found non-empty are now remembered in a WeakSet shared across instances, so later checks are O(1): 2,000 inits with a 6,800-key bundle went from ~750 ms to ~20 ms, the same as a one-key bundle. Only the non-empty result is cached. No API removes single keys from a bundle, so a non-empty bundle stays non-empty, and empty bundles are re-checked every time, so keys added later (backend loads, addResource, addResourceBundle, direct or silent changes) count right away. The only edge case: a bundle emptied by hand with delete on every key while it is still in the store keeps counting as having translations; use removeResourceBundle() for that. Thanks @​dmchoi77 for the detailed report (#2449).

v26.4.2

  • fix: $&, $`, $' and $$ inside a nested value ($t(key)) now stay literal. nest() handed the resolved value straight to String.replace as the replacement argument, so those sequences were read as replacement patterns: $& re-inserted the $t(...) match, $` / $' inserted the text before / after it, and $$ collapsed to $. Through t() the $& case was worse than a wrong string: the nested lookup resets the shared nesting regexp, so the re-inserted $t(...) was matched again on every pass and t() never returned — also under the default escapeValue: true when the value arrives via a variable forwarded through nesting options ($t(key, { "name": "{{name}}" }) with a name containing $&). The value is now $-escaped at the String.replace call, the same guard interpolate() already has, and a non-string value returned by a formatter in the nesting chain ($t(key, myFormat)) is stringified before that. Nested values are still not HTML-escaped (#854). Thanks @​mahirhir (#2447).

v26.4.1

  • fix(types): the selector-form keyPrefix overload of getFixedT() is now available under enableSelector: 'strict'. Its constraint was gated on true | 'optimize' only, so under 'strict' it collapsed to never, the overload dropped out, and the returned t silently lost its keyPrefix scope (t(($) => $.deep) failed with Property 'deep' does not exist on type '{}'). The same call already typechecked under true and 'optimize'. Thanks @​hovelopin (#2446).

  • fix: cloneInstance({ forkResourceStore: true }) now copies the resources at every level. It copied them only down to the namespace objects, so nested keys and arrays stayed shared with the original instance: addResource() with a nested key (fork.addResource('en', 'translation', 'greeting.hello', 'Hi')) or a deep addResourceBundle() on the fork also changed the original instance and every other fork.

The escape pass ran after the unescaped values were written and scanned them again, so t('{{- a}}', { a: '{{b}}', b: 'c' }) returned 'c' instead of '{{b}}'. With pre-built HTML that carries user text, like t('You may contact {{name}} at {{- emailHTML}}.', { name, emailHTML }), that text could pull another variable of the same t() call into the output.

    • MF2: {$name} takes string | number, a variable annotated with :number, :integer, :currency, :percent or :unit (inline or through .input / .local) takes number, :datetime, :date and :time take Date, :string takes string, option and markup variables (minimumFractionDigits=$digits, {#link href=$url}) are required too, .local variables are not arguments, and |quoted literals| and \{ escapes are skipped.
    • interpolationFormatTypeMap overrides a type by ICU format or MF2 function name, e.g. date: Date | number or a custom uppercase: string.
    • Applies to t(), getFixedT(), i18n.t, key prefixes, namespaces, the selector API and react-i18next's Trans values. Messages need literal types, as the resources file from i18next-cli's types command has them.
    • Type-check cost with 1,000 messages and one call each: 1.35s instead of 0.86s with false (TypeScript 6), 0.5s instead of 0.26s with TypeScript 7. Messages that no call uses cost nothing.
  • fix(types): with the default (non-strict) key checks, an options object with a missing or misspelled interpolation variable now reports the missing variable (Property 'name' is missing) instead of '{ nmae: string }' is not assignable to type 'string' from the default-value overload.

26.4.7

  • perf: cloneInstance() no longer inherits preload. loadResources() adds every preload language to each load, and clones copied preload from the parent, so a clone's init() and every changeLanguage() walked all preloaded languages × all namespaces through queueLoad() / hasResourceBundle(), although the parent had already loaded them into the shared store. With i18next-http-middleware (one clone + changeLanguage() per request), 25 preloaded languages and 20 namespaces, that was most of the per-request CPU: the reproduction from the issue went from ~90 µs to ~10 µs per request, the same as with a single language. A clone now only loads what it uses itself: its changeLanguage() no longer waits for parent preload languages that are still loading (the parent's own init() still does), and clone.loadNamespaces() loads the new namespace for the clone's language and fallbacks instead of every preloaded language. clone.loadLanguages() works as before, the parent instance is unchanged, and passing preload to cloneInstance() keeps the old behavior. Thanks @​theMostCuriousHomunculus for the detailed report (#2451).

26.4.6

  • fix: a fallback language whose formatted code is already in the hierarchy is no longer added a second time. toResolveHierarchy() checked the raw fallbackLng value against the list, but the list holds formatted codes, so any fallback written differently from its formatted form slipped through: lng: 'de-CH' with fallbackLng: 'de-ch' gave languages ['de-CH', 'de', 'de-CH'], and the same happened with fallbackLng: 'EN' + cleanCode, lowerCaseLng, and Intl aliases (iw-IL → he-IL). Missing keys were looked up in the same language twice. Only exact duplicates are removed; the order is unchanged. Thanks @​lprnmns (#2450).

26.4.5

  • fix: hasLoadedNamespace(ns, { lng }) no longer stays false forever when the passed in lng is loaded under another code, or not at all. It checked the load state of the raw lng, but loadLanguages() stores a language under its resolved code (de-ch → de-CH, de-CH → de with load: 'languageOnly') and skips a lng outside supportedLngs entirely (only the fallback gets loaded), so that state never got set. react-i18next's useTranslation(ns, { lng }) then never became ready: with useSuspense it kept throwing an already resolved promise and React retried forever (100% CPU, SSR never finished), without it the load effect re-rendered in a loop. It now checks the code the language is actually loaded under, and for a lng outside supportedLngs only waits for the fallback, which is also what t() resolves to. Calls without lng and the precheck (react-i18next's bindI18n: 'languageChanging') are unchanged (react-i18next#1934).

Looks like these dependencies are updatable in another way, so this is no longer needed.
