* feat(ui): add eslint rules for nested ternaries, large inline object args, and long condition chains
Adds three dashboard lint rules to keep new code readable. Nested ternaries
are banned outright via the built-in no-nested-ternary, with the 265 existing
occurrences grandfathered in eslint-suppressions.json so only new ones fail.
Two custom rules ship as a small local plugin under scripts/eslint-rules:
no-large-inline-object-arg flags object literals with 4+ properties passed
straight into a call, nudging toward a named variable, and no-long-condition-chain
flags boolean expressions that combine 4+ conditions, nudging toward a named
boolean. Both are warnings tracked on the existing budget ratchet
(eslint-budgets.json + eslint-metrics.json) with headroom above the current
counts, so they ratchet down over time rather than freezing a baseline. Both
thresholds are configurable rule options and covered by RuleTester unit tests.
* fix(ui): scope no-long-condition-chain to boolean operators, not nullish
Greptile flagged that the rule counted nullish-coalescing chains the same as
&&/|| chains, so a 4-part `a ?? b ?? c ?? d` fallback surfaced "Boolean
expression combines 4 conditions", which is inaccurate since a `??` fallback
is value defaulting, not a condition. Restrict the visitor to && / || nodes so
`??` chains are treated as leaves, while a boolean chain nested inside a `??`
is still caught. Drops 6 miscounted occurrences (240 -> 234).
* chore(ui): sync lint metrics and suppressions with staging
Merge advanced the base branch, adding one no-large-inline-object-arg
occurrence (508 -> 509) and making one grandfathered react-hooks suppression
stale. Regenerate eslint-metrics.json and prune the suppression so the
budget/drift gate passes.
* chore(ui): sync lint metrics with staging
Merge advanced the base, adding four no-large-inline-object-arg occurrences
(509 -> 513). Regenerate eslint-metrics.json so the drift gate passes.
* feat(proxy): type Customer Management response_model for OpenAPI coverage
Add response_model to the five remaining untyped /customer operations
(block, unblock, new, update, delete) so the generated OpenAPI schema
documents a concrete response body. new/update reuse the canonical
LiteLLM_EndUserTable (matching info/list); block, unblock, and delete
get small dedicated models in
litellm/types/proxy/management_endpoints/customer_endpoints.py.
Together with the already-typed info/list/daily-activity routes this
brings the Customer Management group to full response_model coverage.
Regression tests assert each public /customer/* route declares the
expected response_model and that /customer/new surfaces a typed schema
in app.openapi(), so dropping a response_model fails CI.
* fix(proxy): keep budget_id in typed customer responses
Address review feedback on the Customer Management response_model typing.
Greptile flagged that response_model=LiteLLM_EndUserTable on /customer/new
and /customer/update silently drops fields the raw Prisma model_dump()
echoed. Checking the schema, budget_id is the only such scalar column that
was missing from the Pydantic model (created_at/updated_at/tpm_limit do not
exist on litellm_endusertable), so add budget_id to LiteLLM_EndUserTable.
This restores budget_id on new/update and also fixes the pre-existing gap
where /customer/info and /customer/list (already typed) dropped it, which
the UI Customer type expects. A regression test pins budget_id surviving the
response_model filter on /customer/update.
Also document UnblockUsersResponse.blocked_users via a Field description: it
holds the users that remain blocked after the call. The key name predates
this PR and is kept to avoid a backwards-incompatible rename on a beta route.
* fix(proxy): keep nested budget fields in customer responses
response_model=LiteLLM_EndUserTable nests the budget as the narrow write
allowlist LiteLLM_BudgetTable, which silently drops the server-managed
fields the customer endpoints used to return (budget_reset_at, created_at).
Introduce CustomerResponse, a thin response model that nests
LiteLLM_BudgetTableFull (the repo's budget response model), and apply it on
/customer/new, /customer/update, /customer/info and /customer/list. list
also builds CustomerResponse so its budget isn't narrowed at construction
time. created_by/updated_at/updated_by remain omitted, matching how budgets
are returned elsewhere.
The shared LiteLLM_EndUserTable is left untouched: it's constructed in many
places that pass narrow budget instances, and pydantic v2 won't coerce a
budget instance into a wider nested model. Typing only at the response
boundary (where the handler hands FastAPI a dict) sidesteps that. A
regression test pins budget_reset_at + created_at through the filter and
asserts the internal audit fields stay out.
* test(proxy): add golden-master characterization tests for customer responses
Lock the exact JSON body each customer-object endpoint (info/list/new/update)
and delete return today, so the upcoming type-safety refactor of the handlers
is only allowed to land if it reproduces these byte for byte. Pins null-field
inclusion, the nested budget shape (server fields kept, audit fields dropped),
and object_permission reverse-relation stripping. Green against current code.
* refactor(proxy): make the customer response flow type-safe
Replace the untyped dict + bolt-on response_model pattern on the customer
object endpoints with explicit typed construction. A single mapper,
_to_customer_response, validates a DB row into CustomerResponse at one
Any -> typed seam; new/update/info/list now return it (or a list of it) and
carry real -> CustomerResponse / -> List[CustomerResponse] return
annotations, and delete returns DeleteCustomersResponse. basedpyright now
verifies the handlers' return shapes instead of a runtime filter doing it
silently.
This also deletes the four copy-pasted object_permission reverse-relation
cleanup loops: pydantic's extra=ignore drops those undeclared fields during
validation, so the loops were dead code (proven by the golden-master tests,
which stay byte-for-byte green). basedpyright errors on the file drop from
140 to 116, all from removed dict plumbing.
CustomerResponse stays a thin subclass of LiteLLM_EndUserTable so it inherits
the existing validators/config unchanged (behavior preservation); only the
nested budget type is widened.
* refactor(proxy): annotate customer response mapper param as BaseModel
Address review nit: the mapper's untyped `record` added an ANN001 violation.
The incoming rows are pydantic v2 models, so type the param as BaseModel
rather than object (object has no model_dump, which would just move the
problem to basedpyright). This clears the ANN001 and also drops three
basedpyright unknown-type violations the untyped param was adding.
* style(test): ruff format customer endpoint tests
* test(proxy): give customer budget test update mocks a valid model_dump
The type-safe response refactor validates the update result via
_to_customer_response (CustomerResponse.model_validate(record.model_dump())).
These budget tests mocked the end-user update to return a bare MagicMock,
so model_dump() yielded a MagicMock that fails validation. Give each update
mock a minimal valid dict; the tests assert on the prisma calls, not the body.
* chore(ui): regenerate API types from proxy OpenAPI spec
* fix(ui): make generated API types stable across Python versions
Python 3.13 strips a docstring's common leading indentation at compile
time while 3.12 keeps it, so app.openapi() emits differently-indented
description strings depending on the interpreter. The dashboard type
generator ran locally on 3.13 and in CI on 3.12, so schema.d.ts drifted
and the "Verify schema.d.ts matches the proxy OpenAPI spec" check failed
Normalize every description through inspect.cleandoc in the spec dump so
the output is identical regardless of interpreter, then regenerate
* feat(ui): track frontend lint counts in a committed snapshot
Persist the eslint budget-rule counts (no-explicit-any, complexity,
max-depth) to eslint-metrics.json so the trend is queryable straight
from git history and can later feed a dashboard. A CI drift check
regenerated from the same lint report keeps the snapshot honest, so a
PR that shifts a count has to run npm run lint:metrics and commit it
* fix(ui): harden lint-metrics drift check and eslint failure handling
Make the drift comparison symmetric over the union of committed and
actual keys so a phantom rule left in eslint-metrics.json (for example
after a rule is dropped from eslint-budgets.json) is caught instead of
silently passing. Only swallow eslint's lint-errors exit code in the
generator and rethrow anything else, so a fatal eslint failure surfaces
its real output rather than a confusing ENOENT on the missing report
The dashboard calls UI-internal proxy routes that the public /openapi.json hides with include_in_schema=False, so they never reached schema.d.ts and could not be typed. The type generator now force-includes those routes when it dumps the spec for openapi-typescript; this mutates a throwaway interpreter only, so the spec the proxy actually serves is unchanged.
Regenerates schema.d.ts so 86 internal route families (for example /v2/model/info, /global/spend/*, /config/*, /v2/login, /sso/*) are now typed, with no public route removed. This unblocks migrating the dashboard's data fetching onto the typed $api client.
Branch CI note: schema.d.ts is generated; CI regenerates and diffs it via the same gen:api script.
* feat(ui): generate dashboard API types from the proxy OpenAPI spec
Introduces the shared type foundation for the dashboard without touching any
runtime code. The proxy's FastAPI app is the source of truth; app.openapi()
emits the spec and openapi-typescript turns it into src/lib/http/schema.d.ts.
Adds an npm run gen:api script (a Python spec dump piped into openapi-typescript)
and a Check UI API Types Sync CI job that regenerates the file from the live
spec and fails if it drifts, so the committed types can never silently fall out
of step with the backend. The generated file is pinned to openapi-typescript
7.13.0 and excluded from prettier, eslint, and knip, and marked linguist-generated
so it collapses in diffs.
No openapi-fetch and no call-site changes yet; this only makes the types exist.
* chore(ui): tidy gen-api-types script per review
Write the spec dump inside a with-block and clean up the temp dir in a
finally, so repeated local runs don't leave stray ~MB JSON files behind.
* ci(ui): add frontend-lint job enforcing prettier and eslint on changed files
Lints only the files a PR adds or modifies under ui/litellm-dashboard,
so new and touched code must be prettier-clean and eslint-clean while the
existing tree is grandfathered. Skips cleanly when a PR touches no
lintable UI files. This lets us adopt the formatters incrementally
without a repo-wide reformat
* ci(ui): write frontend-lint file lists to $RUNNER_TEMP
Keep the prettier/eslint changed-file lists out of the checkout dir so
they cannot collide with a future source file of the same name
* lint(ui): baseline existing eslint findings so only new ones block
Capture the current error-level eslint findings (318 across 183 files)
in a committed suppressions baseline via eslint --suppress-all. Every
rule stays at its error severity, so any newly introduced violation
fails the frontend-lint gate, while the existing tree is grandfathered;
touching a legacy file never forces fixing its pre-existing issues. CI
runs eslint with --pass-on-unpruned-suppressions so that fixing a
baselined issue does not fail on a now-stale suppression, and the
generated baseline is prettier-ignored since eslint owns its format.
Burn the baseline down over time with eslint --prune-suppressions
* lint(ui): enforce a count budget for explicit any
Make @typescript-eslint/no-explicit-any a warning and cap the total
instead of hard-blocking each new one. A frontend-lint step counts the
repo-wide explicit any and fails only when it exceeds the committed
budget in eslint-any-budget.json. max starts at 2031, ten above the
current 2021, so the next ten land as warnings and the build fails once
that headroom is gone. Lower max over time toward target to ratchet the
count down. New anys still surface as warnings on changed files via the
normal eslint step
* lint(ui): enable zero-cost rules no-var, no-self-assign, react/no-danger
These have no existing violations, so they need no baseline; turning them
on purely blocks new instances. react/no-danger guards against new
dangerouslySetInnerHTML (XSS), no-var enforces let/const, and
no-self-assign catches self-assignment typos. no-debugger is already
enforced by the recommended preset
* lint(ui): add baselined complexity rules
Enable complexity:20, max-depth:4, max-params:4, max-nested-callbacks:4,
with thresholds set near the codebase p99 so only genuine outliers are
flagged. The 272 existing over-threshold functions are grandfathered in
the suppressions baseline; new over-threshold functions block. Lower the
thresholds over time to ratchet complexity down. max-lines-per-function
is intentionally left off since React components are legitimately long
* lint(ui): ban new raw fetch, standardize on React Query
Add a no-restricted-syntax rule flagging bare fetch() calls, pointing
contributors at React Query (@tanstack/react-query). The rule is not
exempted anywhere, including the already-bloated networking.tsx, so all
331 existing fetch calls are grandfathered but no new ones can be added
there or elsewhere. New data access goes through React Query, and the
networking layer can be migrated out and pruned from the baseline over
time
* lint(ui): ban new @tremor/react imports
Add a no-restricted-imports rule flagging imports from @tremor/react so
tremor is phased out rather than spread further. The 232 existing tremor
imports are grandfathered in the baseline; new ones block and point at
antd. Migrate components off tremor and prune the baseline over time
* lint(ui): widen explicit-any budget headroom to 2040
Raise max from 2031 to 2040, giving ~19 of slack over the current 2021
instead of 10
* style(ui): prettier-format eslint.config.mjs
The frontend-lint gate flagged its own config file. Format it so the
prettier check on this PR's changed files passes
* lint(ui): soften complexity and max-depth to warnings
These two are smell metrics with arbitrary thresholds where a legit new
function can trip them, so make them advisory rather than hard-blocking.
They drop out of the baseline (now 963). max-params, max-nested-callbacks,
and the react-hooks rules stay strict since those are clear-cut
* lint(ui): move complexity and max-depth to the count-budget pattern
Generalize the explicit-any budget into a shared lint-budget mechanism:
eslint-budgets.json maps a rule to {max, target} and check-lint-budgets.mjs
counts each across the repo and fails when a count exceeds its max.
complexity (129, max 140) and max-depth (61, max 70) now use the same
slack-plus-counter model as explicit-any (2021, max 2040): they warn
per-file and the build only fails if the repo-wide total crosses the
ceiling. Lower each max toward its target over time
* docs(ui): note pruning the eslint suppressions baseline when fixing lint debt
Remove @neondatabase/api-client and neonctl to address CVE-2026-25639
(axios supply chain vulnerability). Pin all JS dependencies to exact
versions across all package.json files to prevent future supply chain
attacks via semver range resolution.
