Inline comments:
In `@README.md`:
- Around line 131-141: Replace the non-standard script tag attribute
type="javascript" with a valid attribute (either type="text/javascript") or
remove the type attribute entirely so the browser treats it as JavaScript;
update the <script> tag that contains the request object and the call to
sdk.createContextWith(request, {{ serverSideContext.data() }}) to use the
corrected type or no type so the snippet is valid.
- Around line 51-54: The fenced code block containing "Browser --> Your Server
(with API key) --> ABsmartly API" is missing a language specifier; update that
fenced block in README.md to use a language token such as ```text or
```plaintext so the block becomes ```text ... ``` and satisfies linting and
improves rendering consistency.
In `@src/client.ts`:
- Line 268: The retry wrapper call uses the raw instance option
this._opts.timeout instead of the resolved per-request timeout
(options.timeout), causing incorrect retry/timeout accounting; update the call
to tryWith in the function that currently passes this._opts.timeout to instead
pass the already-resolved timeout (e.g., options.timeout) with the same fallback
(options.timeout ?? DEFAULT_TIMEOUT_MS) while keeping the retries fallback
(this._opts.retries ?? DEFAULT_RETRIES) unchanged.
In `@src/context.ts`:
- Around line 835-845: The scheduled publish/refresh timeout handlers call
this._logError in their outer catch, which duplicates errors already logged by
this._flush and this._refresh; remove the outer this._logError calls inside the
setTimeout handlers (the handlers that call this._flush and this._refresh via
the this._publishTimeout and the similar scheduled block at 1038-1048) so that
only the inner _flush/_refresh error paths log the error. Ensure the timeout
handlers still swallow/recover the error (no rethrow) after removing the outer
log to preserve behavior.
In `@src/fetch.ts`:
- Around line 19-32: The current runtime check uses a bare identifier "global"
which can throw ReferenceError in strict browser environments; update the check
to safely detect the environment (e.g., use typeof global !== "undefined" or
globalThis) and prefer globalThis.fetch when available, and only fall back to
importing "node-fetch" if no fetch exists; update the branch that currently
returns global.fetch.bind(global) and the fallback that imports "node-fetch"
(the anonymous function handling url/opts and the import("node-fetch") logic) to
use the safe existence check so no ReferenceError occurs.
In `@src/jsonexpr/operators/match.ts`:
- Around line 13-23: Before compiling untrusted regex patterns, validate them
with a ReDoS-safe checker: import safe-regex2 (e.g. safeRegex) and, after the
text length check and before new RegExp(pattern), call if (!safeRegex(pattern))
{ console.error("Unsafe regex pattern rejected"); return null; } — update the
code around the RegExp compilation and the variables pattern, text,
MAX_PATTERN_LENGTH, MAX_TEXT_LENGTH, and compiled to perform this check so
catastrophic-backtracking patterns are rejected prior to compilation.

In `@src/__tests__/fixes.test.js`:
- Around line 12-15: The file-level jest.mock("../client") and
jest.mock("../sdk") make constructor tests vacuous because they replace real
constructors and bypass _extractClientOptions and _contextOptions logic; to fix,
remove or relocate those module-wide mocks and instead mock only where needed
(or use jest.unmock/ jest.requireActual or jest.isolateModules) so the specific
tests at lines referenced instantiate the real client/sdk constructors and
exercise the merge logic; update the tests that need isolated behavior to
explicitly mock "../provider" and "../publisher" only for their scopes while
leaving "../client" and "../sdk" real for constructor/merge tests so assertions
validate _extractClientOptions/_contextOptions and the actual constructor
merging.
In `@src/context.ts`:
- Around line 230-236: The ready() fast path currently returns
Promise.resolve(true) even after a failed initialization; update ready() so the
immediate return reflects failure by returning Promise.resolve(!this._failed)
when isReady() is true, and ensure the fallback still awaits
this._promise?.then(() => true).catch(() => false) ??
Promise.resolve(!this._failed) so callers receive a deterministic boolean based
on the context's failure state; refer to the ready(), isReady(), this._promise
and this._failed symbols when making the change.
In `@src/sdk.ts`:
- Around line 58-69: SDK._extractClientOptions currently hardcodes agent =
"absmartly-javascript-sdk" and force-casts the result to ClientOptions, hiding a
type mismatch with ClientOptions.agent; fix by aligning runtime value with the
declared type instead of silencing the error: either change the hardcoded string
in SDK._extractClientOptions to the expected literal "javascript-client" or
update the ClientOptions.agent type to include "absmartly-javascript-sdk" (e.g.,
a union), and remove the unsafe `as ClientOptions` cast so the compiler
validates the shape (adjust the extracted variable typing to
Partial<ClientOptions> and only return a properly-typed ClientOptions).

- Around line 333-335: Replace the simple non-empty string checks with a shared
helper that trims whitespace first: add a helper like isNonEmptyString(value) =>
typeof value === "string" && value.trim().length > 0, then use it wherever you
currently check attrName (and the other new validators) so the code throws when
the trimmed string is empty; update the Error messages in the validation
branches (e.g., the block using attrName) to reflect "non-empty, non-whitespace
string" and apply the helper to the other validator sites mentioned (the checks
around lines referencing attrName, experiment/goal/field name validators and the
blocks at 794-799, 824-829) to ensure whitespace-only inputs are rejected
consistently.
- Around line 1067-1078: The JSON parse currently accepts any JSON value (e.g.,
null, array, number) and later code assumes an object, causing errors in _init()
and when checking keys in assignment.variables; after JSON.parse in the block
that sets parsed (and in the similar block around lines 1080-1091), validate
that the parsed value is a plain object (e.g., typeof parsed === "object" &&
parsed !== null && !Array.isArray(parsed") or use a helper isPlainObject) and if
not, set parsed = {} and log or swallow as before; update both occurrences that
assign parsed so downstream uses (experiment.name, assignment.variables) are
safe.
- Around line 530-536: The audience evaluation must fail closed: update
_evaluateAudience to return false (not null) when _audienceMatcher.evaluate
throws, and similarly change any other audience-evaluation blocks referenced
(the ones around the other occurrences at the same logic) so that on exceptions
they log the error via _logError(error as Error) and return false so

- Add ReDoS protection in match.ts using safe-regex2 (replaces narrow
custom regex check that only caught a few quantifier shapes)
- Move SDK/Client constructor-merge tests to fixes-constructors.test.js
so they exercise real classes instead of Jest doubles (file-scope
jest.mock("../client"|"../sdk") in fixes.test.js made the previous
versions vacuous)
- Apply fail-closed semantics to audience evaluation: route both call
sites through _evaluateAudience() and treat any non-true result as a
mismatch, so audienceStrict still protects against malformed audiences
- Update one stale exposure expectation in context.test.js to include
ruleOverride and sdkVersion (post-rebase)
- Document the empty publishDelay/refreshPeriod catch blocks (the
callbacks already log via _logError) and replace `Function` cast in
fetch.ts with a typed signature
The async/await wrappers in _setTimeout/_setInterval scheduled the callback-based _flush/_refresh just to swallow errors that those methods already log internally. Calling them directly drops the dead try/await wrapping and removes the regenerator-runtime polyfill that babel was injecting for the IE10 browser target (which broke build-browser). Also stop destructuring `agent` into `_` in client.test.js — replace with delete to clear the no-unused-vars warning.

(ContextAPI: 'if (result != null) audienceMismatch = !result.get()'). The
cache-validity re-evaluation uses the same null-guarded logic so a null result
no longer needlessly invalidates a cached assignment.
- override(): allow after finalize() (parity with the production SDK, which sets
overrides unconditionally). Keep the input-type validation but drop the
erroneous _checkNotFinalized() guard.
Fixes cross-SDK scenarios 13 (Not Eligible - Traffic Split) and 190
(Post-Finalize override allowed).
The match length-cap/safe-regex/cache hardening changed MATCH edge-case behavior vs the canonical collector and diverged from the other SDKs (inconsistent limits; only a subset hardened). Restore the bare collector-equivalent MatchOperator here and remove the safe-regex2 dependency. The hardening now lives on feat/regex-hardening to land as a coordinated cross-SDK security PR.
The SDK alias used 'Absmartly' (lowercase b); the rest of the codebase uses 'ABsmartly' (client.ts, context.ts, error messages). Align both the named and default exports.
Asserts hashUnit of emoji/CJK units against the shared canonical values, guarding the UTF-8 surrogate-pair encoding (4-byte sequences) across SDKs.

There are a bunch of breaking changes in this PR - I'm wondering if we can avoid a major bump by deprecating old stuff 🤔 Might be too much to do though - we may need to just bite the bullet and push to |
… Data section - Drop the Security Warning: Client-Side Usage block from the README - Restore the publish() intro and example under Publishing Pending Data - De-duplicate the Finalizing section
BREAKING CHANGE: bump to 2.0.0. ready() resolves true (not the Error), unit IDs with astral characters now hash to canonical UTF-8, and audienceMismatch cache invalidation changes for indeterminate audiences. Review feedback from @calthejuggler: - Revert gratuitous input-validation throws on context methods (attribute/peek/treatment/track/variableValue/peekVariableValue/ override/customAssignment/customFieldValue/customFieldValueType and experiments() return); keep only correctness-motivated breaks. - getAttribute(): reverse-scan early-return instead of full-array mutation. - setInterval refresh scheduling collapsed to a one-liner. - sdk.ts: iterate typed clientOptionKeys to drop the double cast; hoist context-option default constants to module scope. - fetch.ts: single typed cast for the global fetch bind. - Reorganize tests: remove fixes.test.js (ReDoS tests stale after revert, EqualsOperator dup'd into eq.test.js) and co-locate the rest into context/sdk/client/abort-controller-shim/fetch-shim test files; rename fixes-constructors.test.js -> constructor-options.test.js, deduped into one describe block. - Rewrite README migration guide for v1 -> v2. npm test 997/997, compile clean, lint clean.
Applies @calthejuggler's suggestion on PR #50 (cleaner than copy-then-delete).
format:check ran 'prettier --check' over the generated js/ and types/ dirs (build output, git-ignored but not prettier-ignored), failing the build on stale artifacts. Add them to .prettierignore alongside es/lib/dist.

Approved per request. Unit coverage and PR CI look good, but the real HTTP/e2e gap remains. Client tests mock ../fetch, and context publish/refresh tests mock client/provider/publisher, so the actual fetch implementation plus public publish/refresh flow is not exercised against a real/local HTTP endpoint. Please add an integration/e2e test using a local HTTP server or equivalent that covers GET/refresh and PUT/publish through the SDK.
Node http server + public SDK exercises the real client doing GET /context (createContext→ready) and PUT /context (publish), asserting the wire contract (JS sends auth headers on GET too). CI-runnable complement to the live e2e.
|
@Pedro-Revez-Silva Addressed the real-HTTP/e2e gap. Hermetic local-HTTP integration test added: `src/tests/local-server-integration.test.js` (commit `7005381`). A Node `http` server on an ephemeral port drives the public SDK (`new SDK({endpoint,...}) → createContext → ready() → treatment + track → publish()`) so the real client (fetch/http) performs an actual GET /context (refresh→ready) and PUT /context (publish). Asserts the wire contract — including the auth headers JS sends on GET (per the contract), and PUT headers + body (hashed/units/publishedAt/goals/exposures). CI already runs on `pull_request`. The full live-backend e2e (real collector, public publish/refresh flow) lives in the cross-sdk-tests repo; this is the hermetic CI-runnable complement inside this repo. |

There was a problem hiding this comment.
The version is already at 2.0.0 (major), which matches your instinct that the UID hashing change needs a major bump — it's a breaking change per semver since it can change variant assignment for unit IDs containing astral characters. Leaving this thread open since it explicitly needs your/Márcio's sign-off, not something for me to resolve unilaterally.

cross-sdk-tests wrapper set actually shipped) and the Dart SDK link
(dart-sdk repo returns 404; only a dart-wrapper exists in
cross-sdk-tests, no standalone published SDK yet).
- src/__tests__/constructor-options.test.js: drop the redundant file
header comment (the describe block name already says the same
thing).
- src/context.ts: reword the override()-after-finalize() comment —
"parity with the production SDK" was ambiguous (JS is itself a
production SDK). Point at the actual source of truth instead:
cross-sdk-tests scenario "190 - Post-Finalize - override() Allowed
(Verified Finalized)", which is explicitly JS-specific ("JS
parity" in its own description).
- src/context.ts: fix an inaccurate comment on the indeterminate-
audience cache check — it claimed the mismatch flag is left at
"false", but it's actually left at whatever it was previously
cached as.
- src/__tests__/context.test.js: give the "should clear assignment
cache when experiment ID changes" test a seed (seedHi=1, seedLo=3)
that resolves to a different variant (1) than
expectedVariants["exp_test_abc"] (2), so the assertion actually
proves the cache was recomputed rather than incidentally re-serving
a still-valid cached variant.
…x client.test.js promise propagation
- context.ts: a throwing custom eventLogger on the "finalize" event
could leave finalize()'s promise permanently unsettled — the throw
from _logEvent("finalize") happened before resolveFinalizing(),
and propagated up through _flush's unguarded callback(), rejecting
_flush's internal promise chain and leaving _flushPromise stuck.
Reordered _finalize's success branch to resolve before logging, and
wrapped _logError/callback invocations in _flush's onFailure/onSuccess
in try/catch so an observer exception can never prevent the flush
promise from settling or strand _flushPromise.
- src/__tests__/context.test.js: added regression coverage for a
throwing eventLogger on both the finalize-success and publish-
failure paths during finalize(); confirmed both hang/timeout against
the pre-fix code and pass after.
- src/__tests__/client.test.js: the unmatched-surrogates query test
didn't return or handle its request() promise chain, so a rejection
would time out instead of failing with a clear error. Return the
chain instead of using an unhandled done() callback.

CHANGES REQUESTED - The requested head advanced during review; the latest fixes address the normal publish/finalize observer paths, but one PR-introduced failed-initialization lifecycle path still lets an observer exception permanently strand finalization.
Reviewed current head 77b582199ac137c2f41ef2568bade813ee54a7a1 against merge-base 816d36107b99d9e34992cc09cd471747dd394337. The review began on requested head 576dd3b2de495d72ce82eb6a622e49a44b6f4917; after the mandatory pre-submission re-fetch found the newer commit, I inspected and revalidated 576dd3b..77b5821 rather than posting a stale review.
Validation on the clean detached current head:
git diff --check, format, lint, and TypeScript compilation passed (lint retained one unused_warning).- 37 Jest suites / 434 tests passed with
--runInBand --detectOpenHandles, including the local real-HTTP GET/publish flow and the new observer-failure regressions. - CJS, ES, development UMD, and minified UMD builds passed.
- Focused built-CJS reproductions verified the new normal transport-success/failure logger protections and the surviving inline finding.
- Exact-head GitHub Actions build and format checks passed.
The earlier blockers for in-flight flush coordination, synchronous publisher recovery, automatic retry, timeout: 0, IE-compatible Promise/query behavior, malformed UTF-16/UTF-8 handling, observer-triggered duplicate sends, UMD alias parity, and the README option are addressed. No PR source changes were made.
…ush() The _failed branch of _flush() (discarding queued events after a failed context initialization) called _logError() unguarded, unlike the transport-failure path below it. A throwing custom eventLogger there threw synchronously out of _flush() itself, before it could clear _pending/_exposures/_goals or invoke the callback — which meant _finalize()'s callback never ran, permanently stranding `_finalizing` with no settlement (worse than a rejection: finalize() would hang forever, and no code path could recover). Wrapped both the _logError() call and the callback invocation in try/catch, matching the pattern already used for the transport-failure and success paths. Added a regression test that reproduces a throwing eventLogger during the discard-after-failed-init flow through finalize() — confirmed it hangs against the pre-fix code and settles correctly (isFinalized: true, pending: 0) after the fix.

@jervasion-absmartly The remaining finding from the latest round (finalize observer-failure regression in the failed-init discard path) is fixed in `e6db825`. The `_failed` branch in `_flush()` (discarding queued events after a failed context init) called `_logError()` unguarded — a throwing eventLogger there escaped `_flush()` synchronously, skipping the callback that settles `_finalize()`'s deferred, so `finalize()` would hang forever with no resolve or reject. Guarded it the same way as the transport-failure/success paths fixed in the previous round, with a regression test reproducing the hang against the pre-fix code. 435/435 tests passing.

If_flushPromiserejects, the recursive_flush(callback, requestOptions)call never runs, socallbackis never invoked and thepublish()orfinalize()promise that owns it never settles. The surrounding comments state that neither handler throws, so this is defence in depth for the same case the cleanup already guards.♻️ Proposed change

CHANGES REQUESTED - The latest commit fixes the previously reported failed-initialization/finalize hang, but exact-head review found two remaining PR-introduced correctness regressions in failure paths.
Reviewed exact head e6db82583aabf200b475f8ffe248d86006043d2d against merge-base/base 816d36107b99d9e34992cc09cd471747dd394337, including the full discussion, prior reviews, unresolved threads, CI, and delta from 77b5821.
Validation on the clean detached exact head:
git diff --check, format, lint, and TypeScript compilation passed (lint retained one unused_warning).- 37 Jest suites / 435 tests passed with
--runInBand --detectOpenHandles, including the real local-HTTP GET/publish flow and the new failed-init observer regression. The first test invocation hit shared/tmpENOSPC; rerunning with a workspace-local Jest cache passed. - CJS, ES, development UMD, and minified UMD builds passed.
- Exact-head GitHub Actions build and format checks passed.
- Focused built-CJS reproductions confirmed both inline findings.
The previous P2 at the failed-init discard logger is fixed: observer failure is isolated, the queue is cleared, and finalize() settles. The earlier review findings remain addressed. No PR source changes were made.
…ronological order
- context.ts: centralized observer-exception isolation into
_logEvent()/_logError() themselves (catch + console.error), instead
of scattering try/catch at each call site. This closes two related
bugs the previous per-call-site guards missed:
* a throwing custom eventLogger on the init-rejection path caused
the internal ready promise to reject, so `await context.ready()`
rejected instead of always resolving `true` as documented (the
v2 migration guide's contract) — isFailed()/readyError() were
still set correctly, but callers following the documented
"ready() never rejects" contract would break.
* a throwing eventLogger on the *successful* ready path was caught
by the adjacent .catch() on the same promise chain, incorrectly
marking a successfully-initialized context as failed.
Simplified the now-redundant local try/catch wrappers in _flush()/
_finalize() added in the previous fix, since _logEvent()/_logError()
can no longer throw.
- context.ts: _flush()'s onFailure restored a failed batch by
push()ing the pre-publish snapshot onto the current queues. Because
the snapshot is taken and the queues are cleared synchronously
before the async publish resolves, any event recorded while that
publish was in flight ends up in the queue before the restore runs
— push() then puts the older, already-recorded events after the
newer ones, delivering them out of chronological order to the
collector on retry. Changed to prepend (concat older ahead of
newer) for both exposures and goals.
- src/__tests__/context.test.js: added regression coverage for a
throwing eventLogger on both ready() failure and success paths, and
for chronological-order preservation when a failed batch is restored
alongside newer events recorded during the in-flight publish. All
reproduced the reported bugs against the pre-fix code.

@jervasion-absmartly Both findings from the latest round fixed in `1bdcf9e`:
Both reproduced against the pre-fix code with the exact scenarios you described, with regression tests added. 438/438 tests passing. |

[P2] Normalize a custom publisher result before chaining
The try above covers the custom publisher call, but this .then access is outside it. A JavaScript publisher that forgets to return its promise—or a beacon-style publisher that returns a boolean—therefore throws synchronously here. I reproduced track() -> finalize() with publish: () => true against the built CJS artifact: finalize() threw publishResult.then is not a function after the queue had been cleared, isFinalizing() stayed true, and every later finalize() returned the permanently pending deferred. The base implementation kept the .then access inside its try, so it rejected and cleared finalizing state instead of bricking the context. Please normalize the extension result (for example through Promise.resolve) or include chaining in the guarded path, and cover a non-Promise custom-publisher result.

[P2] Preserve native AbortSignal.reason semantics in the shim
This newly exposed compatibility property differs from the native controller in observable ways on environments that select this shim. abort(null) must preserve the explicit null, but ?? replaces it with an Error; and because abort() does not return early once signal.aborted is true, a second call overwrites the original reason and dispatches a second abort event. I reproduced both directly: abort(null) yielded an Error, while abort("first"); abort("second") left reason "second" and invoked the listener twice (native behavior retains the first reason and emits once). Please latch the first abort and distinguish an omitted/undefined reason from explicit null, with parity tests for these cases.
