WalkthroughThis change adds TypeScript and Flow utility modules for browser detection, storage, data handling, networking, uploads, cryptography, DOM operations, validation, formatting, and sorting. It also adds utility tests and updates existing tests for TypeScript compatibility. ChangesUtility migration
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to This refactor currently leaves unresolved defects that can duplicate writes, hang or prematurely complete uploads, emit malformed authorization headers, throw in browser environments, lose stored values, and mishandle edge-case inputs. The PR is not merge-ready until these concrete issues are fixed or explicitly accepted. Poem

cache.mergeto throw.This test passes when
cache.mergedoes not throw because the assertion runs only insidecatch. UsetoThrowto verify both the exception and its message.Proposed fix
- try { - cache.merge('foo', { b: 2 }); - } catch (e) { - expect('Key foo not in cache!').toBe(e.message); - } + expect(() => cache.merge('foo', { b: 2 })).toThrow('Key foo not in cache!');🤖 Prompt for AI Agents

64-67: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winPreserve the original runtime inputs.
Number(...)changes the values before the utility receives them. In particular,Number('')is0, so Line 66 does not test a nonnumeric input. Use a test-only cast if this suite must verify the JavaScript runtime contract.Proposed fix

Inline comments:
In `@src/utils/env.ts`:
- Around line 2-3: Update isDevEnvironment so it checks typeof process !==
'undefined' before accessing process.env, while preserving the existing
test-or-dev NODE_ENV result for environments where process exists.
In `@src/utils/LocalStore.ts`:
- Around line 51-61: Update setItem and the corresponding LocalStore
implementation in src/utils/LocalStore.ts lines 51-61 and
src/utils/LocalStore.js.flow lines 77-86 to store values in memory when
localStorage.setItem fails, and ensure reads for those failed-write keys use the
memory fallback. Preserve normal localStorage behavior for successful writes.
In `@src/utils/parseCSV.js.flow`:
- Around line 1-11: Add the Flow pragma to the file and update the parseCSV
function signature so text is an optional nullable string parameter and the
function returns Array<string>, matching the TypeScript contract; do not make
text a required ?string parameter.
In `@src/utils/TokenService.ts`:
- Around line 20-46: Update getToken in src/utils/TokenService.ts (lines 20-46)
and its Flow counterpart in src/utils/TokenService.js.flow (lines 26-52) to
accept token-pair objects only when every present read or write field is a
string, and change both methods to return Promise<TokenLiteral>. Update
TokenLiteral to represent the supported write-only pair, preserving string,
null, and undefined handling.
In `@src/utils/uploads.ts`:
- Around line 169-175: Update getFileFromEntry in src/utils/uploads.ts (lines
169-175) and src/utils/uploads.js.flow (lines 236-241) to pass the Promise
reject callback as entry.file’s second callback, ensuring file-read errors
reject rather than leaving getFileFromDataTransferItem pending.
- Around line 135-144: Update getEntryFromDataTransferItem in
src/utils/uploads.ts and its corresponding implementation in
src/utils/uploads.js.flow to return a nullable entry when no get-entry API
exists or the selected API returns null, avoiding entry.call when unavailable.
Guard all consumers, including getDataTransferItemId() and
src/api/uploads/FolderUpload.js at lines 121-124, before dereferencing the
entry; the sibling site requires the same helper behavior and consumer safety.
In `@src/utils/Xhr.ts`:
- Around line 129-137: Restrict network-error retries in the retryability logic
of src/utils/Xhr.ts lines 129-137 to requests using RETRYABLE_HTTP_METHODS,
while preserving the existing rate-limit and retryable-status checks. Mirror the
same policy in src/utils/Xhr.js.flow lines 139-147 so both implementations
require an idempotent method for network retries.
- Around line 434-496: The upload request promise is not returned from the
getHeaders callback. In src/utils/Xhr.ts lines 434-496, return the this.axios
promise chain from the getHeaders callback; mirror the same returned
promise-chain change in src/utils/Xhr.js.flow lines 439-501, preserving the
existing timeout cleanup and success/error handlers.
- Around line 499-507: Update abort() in src/utils/Xhr.ts at lines 499-507 and
mirror the same change in src/utils/Xhr.js.flow at lines 509-516: cancel the
POST and OPTIONS request paths, clear any retry timeout, and reject retry
promises that are being invalidated so they settle. Preserve the existing axios
cancellation behavior.
- Around line 57-63: Replace the shared instance retryCount state with
request-scoped retry tracking in the Xhr implementation, ensuring concurrent
requests do not share a retry budget; update src/utils/Xhr.ts lines 57-63 and
mirror the request-scoped state contract in src/utils/Xhr.js.flow lines 61-67,
using the existing request/retry flow symbols.

Minor comments:
In `@src/utils/__tests__/Cache.test.ts`:
- Around line 54-59: Update the test for cache.merge in “should not merge non
existant items” to assert that the call throws and that the thrown error message
is “Key foo not in cache!”. Replace the try/catch-only assertion with a Jest
toThrow-based expectation so the test fails when no exception is raised.
In `@src/utils/__tests__/timestamp.test.ts`:
- Around line 64-67: Update the convertTimestampToSeconds tests to pass the
original string inputs directly, using a test-only type cast if required by
TypeScript; ensure the empty-string case remains a genuinely nonnumeric runtime
input rather than Number('') producing 0.
In `@src/utils/__tests__/webcrypto.test.ts`:
- Around line 8-10: Update CryptoOperation.oncomplete to type its result as
ArrayBuffer. In both msCrypto tests, store the legacy digest promise, await it,
and assert directly with resolves or rejects; apply the same stored-promise and
direct rejects pattern to the js-sha1 rejection test.
In `@src/utils/Browser.ts`:
- Around line 37-49: Update Browser.isMobileSafari() to exclude iOS user agents
branded CriOS, FxiOS, EdgiOS, and OPiOS while preserving true Mobile Safari
detection. Add user-agent tests covering each excluded brand.
In `@src/utils/dom.ts`:
- Around line 19-25: Update the editability checks in src/utils/dom.ts lines
19-25 and src/utils/dom.js.flow lines 24-30 to use element.isContentEditable
instead of testing contenteditable attribute presence, while explicitly
excluding false-valued contenteditable elements; preserve the existing input,
select, and textarea handling.
- Around line 95-100: Update the focus logic in the DOM utility to use a
structural focus-function check instead of restricting matches to HTMLElement,
allowing focus-capable SVGElement results to be focused; retain the focusRoot
fallback for non-focusable matches. Parse the enumerated contenteditable state
so empty and "false" values are treated as non-editable, and add tests covering

domain and ownerEmailDomain to the same case before comparing them. Apply the

in src/utils/sorter.ts lines 55-60 and src/utils/sorter.js.flow lines 62-68; no
implementation changes are needed.
In `@src/utils/validators.ts`:
- Around line 1-2: Add local TypeScript declarations for the `@hapi/address` and
`@hapi/address/lib/tlds` imports used by validators.ts, giving Address and
tldsHapi explicit types so the Set construction is statically checked without
relying on implicit any.

Inline comments:
In `@src/utils/env.ts`:
- Around line 2-3: Update isDevEnvironment so it checks typeof process !==
'undefined' before accessing process.env, while preserving the existing
test-or-dev NODE_ENV result for environments where process exists.
In `@src/utils/LocalStore.ts`:
- Around line 51-61: Update setItem and the corresponding LocalStore
implementation in src/utils/LocalStore.ts lines 51-61 and
src/utils/LocalStore.js.flow lines 77-86 to store values in memory when
localStorage.setItem fails, and ensure reads for those failed-write keys use the
memory fallback. Preserve normal localStorage behavior for successful writes.
In `@src/utils/TokenService.ts`:
- Around line 20-46: Update getToken in src/utils/TokenService.ts (lines 20-46)
and its Flow counterpart in src/utils/TokenService.js.flow (lines 26-52) to
accept token-pair objects only when every present read or write field is a
string, and change both methods to return Promise<TokenLiteral>. Update
TokenLiteral to represent the supported write-only pair, preserving string,
null, and undefined handling.
In `@src/utils/uploads.ts`:
- Around line 169-175: Update getFileFromEntry in src/utils/uploads.ts (lines
169-175) and src/utils/uploads.js.flow (lines 236-241) to pass the Promise
reject callback as entry.file’s second callback, ensuring file-read errors
reject rather than leaving getFileFromDataTransferItem pending.
- Around line 135-144: Update getEntryFromDataTransferItem in
src/utils/uploads.ts and its corresponding implementation in
src/utils/uploads.js.flow to return a nullable entry when no get-entry API
exists or the selected API returns null, avoiding entry.call when unavailable.
Guard all consumers, including getDataTransferItemId() and
src/api/uploads/FolderUpload.js at lines 121-124, before dereferencing the
entry; the sibling site requires the same helper behavior and consumer safety.
In `@src/utils/Xhr.ts`:
- Around line 129-137: Restrict network-error retries in the retryability logic
of src/utils/Xhr.ts lines 129-137 to requests using RETRYABLE_HTTP_METHODS,
while preserving the existing rate-limit and retryable-status checks. Mirror the
same policy in src/utils/Xhr.js.flow lines 139-147 so both implementations
require an idempotent method for network retries.
- Around line 434-496: The upload request promise is not returned from the
getHeaders callback. In src/utils/Xhr.ts lines 434-496, return the this.axios
promise chain from the getHeaders callback; mirror the same returned
promise-chain change in src/utils/Xhr.js.flow lines 439-501, preserving the
existing timeout cleanup and success/error handlers.
- Around line 499-507: Update abort() in src/utils/Xhr.ts at lines 499-507 and
mirror the same change in src/utils/Xhr.js.flow at lines 509-516: cancel the
POST and OPTIONS request paths, clear any retry timeout, and reject retry
promises that are being invalidated so they settle. Preserve the existing axios
cancellation behavior.
- Around line 57-63: Replace the shared instance retryCount state with
request-scoped retry tracking in the Xhr implementation, ensuring concurrent
requests do not share a retry budget; update src/utils/Xhr.ts lines 57-63 and
mirror the request-scoped state contract in src/utils/Xhr.js.flow lines 61-67,
using the existing request/retry flow symbols.

input rather than Number('') producing 0.
In `@src/utils/__tests__/webcrypto.test.ts`:
- Around line 8-10: Update CryptoOperation.oncomplete to type its result as

direct rejects pattern to the js-sha1 rejection test.

Remove the unmatched closing parenthesis.
Lines 41, 84, 127, and 163 end the toThrow call with ));. expect(...) is already closed before .rejects, so the second closing parenthesis is unmatched. TypeScript cannot parse this test file.
Proposed fix
- expect(Tokenservice.getToken('file_123', {} as unknown as Token)).rejects.toThrow(/Bad id or auth token/));
+ expect(Tokenservice.getToken('file_123', {} as unknown as Token)).rejects.toThrow(/Bad id or auth token/);Apply the same one-parenthesis removal to the assertions ending on Lines 84, 127, and 163.
Also applies to: 82-84, 125-127, 161-163

Use a null-prototype cache for arbitrary keys.
At Line [8], this.cache uses a normal object. At Line [18], direct assignment treats the key __proto__ as a prototype setter. set('__proto__', value) therefore does not create a cache entry, so has() and get() return incorrect results.
Initialize the cache with Object.create(null) or use Map.
