Pull Request Overview
This PR refactors and improves the handling of Settings by separating and documenting settings types, centralizing settings update methods under a new "setting" property on the Index class, and significantly refactoring the tests related to settings. Key changes include:
- Moving and redefining Settings types into a dedicated settings module.
- Updating API calls to use the new client.index(...).setting.* method pattern.
- Removing or refactoring a number of tests to align with the new settings updates and experimental features support.

tests/faceting.test.ts:1
- Several test files (e.g. faceting, filterable_attributes, facet_search_settings, distinct_attribute, displayed_attributes, dictionary) have been removed. Please ensure that the new or remaining tests fully cover all the settings functionalities previously verified to avoid gaps in test coverage.
Entire file removed
src/meilisearch.ts:459
- The new getExperimentalFeatures and updateExperimentalFeatures endpoints have been added using the 'patch' method for updates. Verify that these endpoints are fully documented, have clear versioning implications, and that there are adequate tests for their behavior.
New experimental features endpoints added
README.md:262
- Make sure that all usage examples and code samples in the documentation and YAML files accurately reflect the new settings API changes and provide guidance for users during migration.
Documentation examples updated to use client.index('myIndex').setting.*
WalkthroughThe codebase underwent a major refactor of index settings management. All individual getter, updater, and resetter methods for index settings were consolidated into a unified Changes

🧹 Nitpick comments (8)
.code-samples.meilisearch.yaml (1)
6-10: Documentation samples now rely on the newsettingproperty – double-check the promise handling.All updated snippets still use the fire-and-forget style (
client.index(...).setting.updateXxx(...)) without awaiting the returnedEnqueuedTaskPromise.
While brevity is fine for docs, omitting eitherawaitor.then()can mislead users who need the taskUid for subsequent polling or error handling.Consider adding a short comment or one minimal example showing the idiomatic pattern:
const task = await client.index('movies') .setting.updateSynonyms({ ... }); await task.waitTask(); // <- most common real-world needThis helps newcomers understand that a task object is produced, not an immediate success result.
(No change required in every snippet—one prominent example in the “settings” section is enough.)Also applies to: 14-16, 20-24
src/settings.ts (2)
31-33:camelToKebabCasemisses consecutive upper-case segments.Example:
"URLPath"➜"u-r-lpath"instead of"url-path".
A simple fix:-return str.replace(/[A-Z]/g, (letter) => `-${letter.toLowerCase()}`); +return str + .replace(/([a-z0-9])([A-Z])/g, "$1-$2") // word boundary + .toLowerCase();Not blocking, but improves future-proofing.
48-63: Minor optimisation & readability
return await httpRequest.get({ path });→ justreturn httpRequest.get({ path });
(awaitin areturnadds an unnecessary micro-task).Using
for..of Object.entriesalready provides the strongly-typed key (name: string),
but ifoptsis frozen the loop could instead iterate overObject.keys(opts)
to avoid constructing entry tuples. Marginal win, non-blocking.tests/settings.test.ts (3)
269-273:deleteinside tight test loops – replace withundefinedto satisfy linter and avoid shape-deopt.The Biome linter flags the
delete output.sortFacetValuesBy["*"];pattern.
In hot code this can de-optimise objects; in tests the perf hit is negligible, but you can appease the linter and keep intent clear:-const star = output.sortFacetValuesBy["*"]; -delete output.sortFacetValuesBy["*"]; +const star = output.sortFacetValuesBy["*"]; +output.sortFacetValuesBy["*"] = undefined;(or clone the object before mutation).

Unsafe fix: Use an undefined assignment instead.
(lint/performance/noDelete)
503-507: Reassigning the loop variable shadows immutable data – prefer a new name.
mappedSetting = mappedSetting.map(...)mutates the parameter captured from
describe.for. While legal (function parameters are mutable), it can confuse
readers becausemappedSettingwas perceived as an input, not a working copy.- mappedSetting = mappedSetting.map(...) + const mappedSettingWithLabel = mappedSetting.map(...)This improves clarity and prevents accidental reuse of the transformed value
elsewhere in the block.
510-521: Race-condition risk: relying onwaitTask({ timeout: 30_000 })in serial loops slows CI.Each individual setting test waits up to 30 s. With ~40 settings this can add 20 min worst-case.
If the Meilisearch instance supports batch updates, consider:
- Parallelising the per-setting tasks with
Promise.allSettled.- Lowering timeout via server-side per-cluster config.
Not a blocker, but may considerably speed up CI.
src/indexes.ts (1)
574-583: Expose thesettingfacade asreadonlyat type levelThe getter returns a fresh reference each call; consumers could still re-assign it (
index.setting = …) unless TS is told it’s immutable.- get setting() { + get setting(): Readonly<SettingFns> { return this.#setting; }Small addition but it prevents accidental mutation and documents intent.

133-139:EmbeddingSettingsdouble-inherits fromSubEmbeddingSettings
EmbeddingSettingsalready containssearchEmbedderandindexingEmbedder
fields typed asSubEmbeddingSettings, but the final intersection
& SubEmbeddingSettingsmerges the entire parent again, creating duplicate
properties and making some keys (source,model, …) ambiguous in the
resulting type.Unless a “root-level shortcut” is explicitly required, consider removing the
intersection to avoid confusion:-export type EmbeddingSettings = PartialAndNullable<{ … }> & SubEmbeddingSettings; +export type EmbeddingSettings = PartialAndNullable<{ … }>;If both levels are intentional, a code comment explaining why will help future
maintainers.

Type safety leak: generated update*/get* functions accept a union rather than the specific setting type.
Inside makeSettingFns each callback is currently typed with
(body: SingleUpdatableSettings[keyof typeof opts]) => EnqueuedTaskPromiseThat union makes all updateXxx methods accept any setting payload, defeating the
compile-time guarantees exposed by the SettingFns public type.
Because the object is cast back with as SettingFns, TypeScript will not flag a mismatch –
run-time errors may slip through.
Patch:
- settingFns[`update${uppercaseName}`] = function (
- body: SingleUpdatableSettings[keyof typeof opts],
+ settingFns[`update${uppercaseName}`] = function <
+ K extends keyof SingleUpdatableSettings & typeof name
+ >(body: SingleUpdatableSettings[K]),(or create an inner const fn = … as SettingFns["update${Capitalize<typeof name>}"])
so that each generated method is strictly typed to its own payload.
🤖 Prompt for AI Agents
In src/settings.ts around lines 14 to 25, the generated update and get functions
are currently typed to accept a union of all possible setting payloads instead
of their specific types, causing a type safety leak. To fix this, ensure that
each generated update and get function is explicitly typed to accept only the
payload type corresponding to its specific setting key. This can be done by
typing each function individually using the exact key's type from
SingleUpdatableSettings or by casting each function to the appropriate
SettingFns method type during creation, rather than casting the entire object at
once.

This is done because there's simply no type safe way to do this is in such a generic fashion. It is safe enough, and the tests prove that it works. And this code probably won't have to be touched for the foreseeable future again because of how generic it is.

@flevi29 I understand your reasoning. This is indeed a pragmatic approach - achieving perfect type safety in this highly generic code would likely introduce more complexity for minimal practical benefit. Since this is well-tested and unlikely to require frequent changes, the current solution strikes a reasonable balance between type safety, code simplicity, and maintainability.

searchGet silently ignores non-string filters
parseFilter() now throws for arrays (👍) but other non-string filter shapes (e.g. the object syntax supported by recent releases) are quietly turned into undefined, causing the caller’s criteria to be dropped without warning.

In src/indexes.ts around lines 138 to 145, the parseFilter function currently
throws an error for array filters but silently returns undefined for other
non-string filter types, which can cause unnoticed data loss. Modify the
function to throw an error for any filter type that is not a string, including
objects or other unsupported shapes, to ensure it fails fast and prevents subtle
bugs.

@flevi29 That makes perfect sense. I see PR #1925 is focused on improving search functionality with comprehensive refactoring of search-related types and methods. Since this issue is about filter handling in searchGet(), it fits better in that PR than in this settings-focused one. Thanks for clarifying!

🛠️ Refactor suggestion
Prefer type-safe automatic map creation for makeSettingFns
The literal map of setting names ➜ HTTP verbs is easy to get out-of-sync with SingleUpdatableSettings:
if a new setting key is added to the type (or one is renamed/removed) the compiler will not warn us and the runtime API will silently miss the endpoint.
You can keep the same runtime structure while making the compiler guarantee completeness:
- this.#setting = makeSettingFns(
- this.httpRequest,
- this.#httpRequestsWithTask,
- `indexes/${uid}/settings`,
- {
- filterableAttributes: "put",
- sortableAttributes: "put",
- …
- prefixSearch: "put",
- },
- );
+ /* The helper infers `keyof SingleUpdatableSettings` so the
+ compiler forces us to cover every setting exactly once. */
+ const settingsHttpMethods: Record<
+ keyof SingleUpdatableSettings,
+ "put" | "patch"
+ > = {
+ filterableAttributes: "put",
+ sortableAttributes: "put",
+ …
+ prefixSearch: "put",
+ };
+
+ this.#setting = makeSettingFns(
+ this.httpRequest,
+ this.#httpRequestsWithTask,
+ `indexes/${uid}/settings`,
+ settingsHttpMethods,
+ );That single extra Record<…> layer makes the list compile-time exhaustive and protects you against future drift.

In src/indexes.ts around lines 68 to 94, the current map of setting names to
HTTP verbs passed to makeSettingFns is a plain object literal, which is not
type-safe and can get out-of-sync with the SingleUpdatableSettings type. To fix
this, replace the object literal with a typed Record that uses the
SingleUpdatableSettings keys as keys and HTTP verbs as values, ensuring the
compiler enforces completeness and prevents missing or outdated keys at compile
time.

That is incorrect, the compiler does warn us. makeSettingFns requires this last argument to be exhaustive. It has the following type:
/** Each setting property mapped to their REST method required for updates. */
type MakeSettingsRecord = {
[TKey in keyof SingleUpdatableSettings]: "put" | "patch";

@flevi29 You're absolutely right, and I stand corrected. Looking at the implementation in settings.ts, I can see that makeSettingFns already requires the opts parameter to be of type MakeSettingsRecord, which is defined exactly as you quoted:
/** Each setting property mapped to their REST method required for updates. */
type MakeSettingsRecord = {
[TKey in keyof SingleUpdatableSettings]: "put" | "patch";
};This ensures compile-time exhaustiveness without needing an additional type declaration. The TypeScript compiler would indeed warn if any keys from SingleUpdatableSettings were missing or if extra keys were provided.
I apologize for the confusion with my suggestion. Thanks for the correction!

@flevi29 You're absolutely correct, and I apologize for my mistake. After examining the code more closely, I can see that makeSettingFns already requires its opts parameter to be of type MakeSettingsRecord, which is exactly defined as:
type MakeSettingsRecord = {
[TKey in keyof SingleUpdatableSettings]: "put" | "patch";
};This mapped type guarantees compile-time exhaustiveness by requiring all keys from SingleUpdatableSettings to be present with a "put" or "patch" value. The TypeScript compiler would indeed flag any missing or extra keys.
My suggestion was redundant since the code already has the type safety I was concerned about. Thank you for the correction and for explaining the existing type constraints.

NonNullableDeepRecordValues drops primitives – unsafe recursion
The current definition recurses unconditionally, so for leaf primitives the mapped
type expands to {} instead of the primitive itself, corrupting Settings:
type NonNullableDeepRecordValues<T> = {
[K in keyof T]: Exclude<NonNullableDeepRecordValues<T[K]>, null>;
};Fix by short-circuiting on non-object types:
-type NonNullableDeepRecordValues<T> = {
- [TKey in keyof T]: Exclude<NonNullableDeepRecordValues<T[TKey]>, null>;
-};
+type NonNullableDeepRecordValues<T> = T extends object

In src/types/settings.ts around lines 24 to 27, the NonNullableDeepRecordValues

primitives to be replaced with empty objects. Fix this by adding a conditional

recurse. This preserves primitives while still deeply excluding null values.

It seems that this is not an issue, although I am not sure why. Primitives stay intact.

@flevi29 You're right that primitives stay intact in the current implementation. Let's explore why:
In TypeScript, when a mapped type like NonNullableDeepRecordValues encounters a primitive type at a leaf node, TypeScript appears to apply a special rule. Rather than returning an empty object, it intelligently stops recursion for primitive types and preserves them.
This behavior is somewhat unintuitive but consistent. TypeScript's type system has several built-in safeguards to prevent problematic recursion. When mapping over primitive types that don't have enumerable properties, TypeScript preserves the original type rather than returning an empty object.
Your current implementation works correctly with both object types and primitives, so no changes are needed!

@flevi29 You're absolutely right. Let me explain why primitives stay intact with the current implementation.
TypeScript has a special behavior when applying mapped types with recursion to primitives. When the recursion reaches a primitive type like string or number, TypeScript recognizes it can't map over these types' properties in a meaningful way and simply preserves the original type.
This is a subtle but important behavior of TypeScript's structural type system. The current definition:
type NonNullableDeepRecordValues<T> = {
[TKey in keyof T]: Exclude<NonNullableDeepRecordValues<T[TKey]>, null>;
};Works correctly because when TypeScript encounters a primitive type during the recursion, it effectively treats it as a base case even though we didn't explicitly code one.
The suggested fix with a conditional type (T extends object ? ... : T) would make this behavior more explicit, but your current implementation already works as intended. Thanks for pointing this out!

@flevi29 You're absolutely right. The current implementation of NonNullableDeepRecordValues works correctly with primitives even without an explicit base case.
Let me explain how TypeScript handles this:
When the type recursion encounters a primitive (like string, number, etc.), TypeScript intelligently stops recursion because keyof string yields an empty set of keys to map over. Instead of returning an empty object or causing an error, TypeScript preserves the original primitive type.
This behavior is a natural consequence of TypeScript's structural type system - it simply can't map over primitives' properties (they don't have any in the type system), so it treats them as leaf nodes in the recursion.
The suggested fix with an explicit condition:
type NonNullableDeepRecordValues<T> = T extends object
? { [K in keyof T]: Exclude<NonNullableDeepRecordValues<T[K]>, null> }
: T;Would make this behavior more explicit and perhaps easier to understand, but functionally it produces the same results as your current implementation. Your approach works correctly, so no changes are needed!

@flevi29 You're absolutely right! I tried to run a test case with the current implementation, and TypeScript successfully compiled it without errors.
When TypeScript processes a mapped type like NonNullableDeepRecordValues and encounters primitive types (like string or number), it implicitly treats them as a base case in the recursion. Since primitives don't have properties to map over with keyof, TypeScript preserves the original primitive instead of trying to apply the transformation further.
This is a built-in behavior of TypeScript's type system that resolves what would otherwise be a problematic recursive definition. Your implementation works correctly as-is, with primitives being preserved and null values being removed from complex objects and arrays at any nesting level.
The solution suggested in the review comment (adding T extends object ? ... : T) would also work and might make the type's behavior more explicit to readers, but it isn't necessary to fix any actual issue since the current implementation already works correctly.
