You give it a flag key and the constant value the gate now always returns; it does the constant propagation, dead-branch elimination, and cross-file wrapper inlining that a line-based tool (or an LLM) can't do reliably. ## What it does Given `--param flag= --param value=`: 1. **Replaces every flag read** with the boolean literal: - Backend: `await checkGate({ gateName: StatsigFlags.KEY, user })` or `gateName: KEY_CONST` - Frontend: `useGateValue(KEY)` / `useFeatureGate(KEY)` 2. **Propagates** `const isX = ` bindings into their uses, including: - `Promise.all` array destructuring: `const [a, b] = await Promise.all([, other()])` removes the slot and array element in tandem (plain `Promise.all` only — `allSettled`/`race` reshape results, so only the inner call is substituted). A `Promise.all` left with one element collapses: `const [a] = await Promise.all([x])` → `const a = await x` - shorthand object properties: `{ isX }` becomes `isX: ` 3. **Folds and deletes dead code**: `if/else`, early-return guards, ternaries (including identical arms), `!`, unreachable statements after a folded `return`/`throw`, empty React effects, and logical chains: - literal on the **left** (`true && x` → `x`, short-circuit drops the rest); - the **identity element** in a non-terminal slot, any operand types (`a && true && c` → `a && c`, `a || false || c` → `a || c`); - a **terminal** right literal only when the left is provably boolean by syntax (a comparison/`!`/logical-of-those) — `a === b && true` → `a === b`; - **annihilator tail-drop**: when the left is provably always-truthy (`||`) / always-falsy (`&&`), the unreachable right operand is dropped (`(x || true) || y` → `x || true`); - **test-position truthiness**: in an `if`/ternary condition, `x || true` (any types) is always-truthy so the branch folds. Value-position residue that needs real type inference (e.g. `x || true` assigned to a variable) is left for a human. 4. **Inlines wrapper functions across files** (semantic mode): a function whose body reduces to exactly `return ` is inlined at every caller workspace-wide, then deleted — including exported wrappers like `isNewDashboardEnabled()`. Caller files get the same propagation/folding cascade. 5. **Removes the flag's enum member** (a `StatsigFlags` enum) and the **flag-key constant** (`export const MY_FLAG = 'my_flag'`) once no references remain workspace-wide. 6. **Drops now-unused flag-support imports** and **file-local helpers this migration orphaned** (opt-out: `--param removeOrphans=false`). 7. **Removes always-constant object-property params** (opt-in: `--param removeConstParams=true`): when the flag leaves `f({ x: true, … })` and **every** call site passes `x` the same literal, `x` is removed from the free function's destructured param (pattern + inline type + body) and from every call. Handles object-property params (`f({ x })`, including shorthand) and single positional params (`f(true)` → `f()`), for `function` declarations and arrow-/function-expression consts. Chased **transitively** — if `f` forwarded `x` into `g({ y: x })` or `g(x)`, `g`'s param goes too (bounded, `--param maxParamRounds`). **Skipped** (left for a human): methods (`svc.m(…)`), **default-exported functions**, multi-arg positional calls, named (non-inline) param types, params with defaults, and object spreads — see safety notes. The same pass also removes an **always-literal prop of a local (non-exported) React component** — `` where every usage passes the same literal threaded from the flag: the prop is dropped from the destructure, its type member, and every `` usage, then the body is inlined and folded. ## Usage All invocations below do the **full cross-file transform** — the workflow declares `semantic_analysis: workspace`, so wrapper inlining and dead-const removal work through the registry too. Run on a CLEAN branch and review `git diff` — git is the undo mechanism. From the registry (published package): ```bash # Preview first — the engine suppresses cross-file writes under --dry-run: codemod run remove-statsig-feature-flag -t . \ --param flag=ENABLE_NEW_DASHBOARD --param value=true --dry-run # Apply, then let Biome tidy the whitespace deletions leave behind: codemod run remove-statsig-feature-flag -t . \ --param flag=ENABLE_NEW_DASHBOARD --param value=true pnpm format ``` From the local workflow (before publishing, or to iterate): ```bash npx codemod workflow run -w tools/codemods/remove-statsig-flag -t . \ --param flag=ENABLE_NEW_DASHBOARD --param value=true pnpm format ``` Direct script run (one language at a time, explicit workspace root): ```bash npx codemod jssg run tools/codemods/remove-statsig-flag/scripts/codemod.ts \ --language typescript -t src --semantic-workspace . \ --param flag=ENABLE_NEW_DASHBOARD --param value=true \ --max-threads 1 --allow-dirty --no-interactive ``` `flag` accepts any of: the **enum member name** (`ENABLE_NEW_DASHBOARD`), the **gate-key constant name** (`SHOW_BETA_BANNER`), or the **Statsig gate string itself** (`enable_new_dashboard`) — the string is resolved (via the semantic provider) to whichever const(s)/enum member(s) hold it, so it works even when different files alias the same gate under different constant names. `value` is whatever the gate resolves to in production — check Statsig before running. Pass `--param value=false` for a flag rolled out to `false`. **⚠️ Preview with `codemod run --dry-run` / `codemod workflow run --dry-run`, NOT `jssg run --dry-run`.** Cross-file inlining uses `SgRoot.write()`, and the transform can't detect dry-run itself. The workflow engine suppresses those writes in dry-run (safe preview); the low-level `jssg run --dry-run` does **not** — it will write cross-file changes to disk. Either way, run on a clean branch and use `git diff` as the undo mechanism. Params: | param | default | effect | |---|---|---| | `flag` | (required) | flag key to remove | | `value` | `true` | the rolled-out boolean | | `removeOrphans` | `true` | remove file-local helpers orphaned by this migration | | `inlineWrappers` | `true` | cross-file wrapper inlining + flag-const removal (needs semantic mode — on by default via the workflow) | | `removeConstParams` | `false` | remove always-constant params from free functions **and always-literal props from local components** (opt-in; needs semantic mode) | | `maxParamRounds` | `32` | how many transitive hops of param removal to chase (1 = single hop; capped at 200) | ## Safety model — what it will NOT do Correctness beats completeness. When a rewrite can't be proven safe, the code is left for a human instead of guessed: - **Files the flag never touched are left byte-identical.** Simplification never runs on unrelated files, so pre-existing `const x = true` constants elsewhere are not folded. (Within files the flag *did* touch, folding may clean up adjacent literal residue — bounded and semantics-preserving.) - **Wrapper inlining requires proof.** Only fires when the semantic provider resolves the wrapper, its body is exactly `return `, every reference is a plain call (never passed as a value) with side-effect-free arguments, and every caller is inside the semantic workspace. Type-position references (`x: StatsigUser`) count as usage, so imports stay when used as types. - **Constant removal requires zero workspace references.** The exported flag-key const is removed only when `references()` proves the definition is the last remaining mention. - **`Promise.allSettled`/`race`/`any` destructures are left alone** (result shape differs); only the inner call becomes a literal. - **Skips on shadowing or destructuring re-bindings** of the same name, including array-destructure elements, renamed/rest object-destructure bindings, and `typeof x` type queries (any of these blocks inlining of that binding entirely, rather than partially rewriting it). - **Exported `const` bindings are never inlined/removed** in phase 2 — an unrelated `export const DEBUG = false` in a flag-touched file is left alone (only phase 3's orphan pass, which already checks this, may remove one). - **`if ()` with no `else` never deletes the statement outright when that would orphan the surrounding syntax.** An `else if` — the if_statement is wrapped in an optional `else_clause` — has the whole `else` clause removed cleanly (not left as a dangling `else ;`). A brace-less `if`/`while`/`for`/`do` body, which has no such optional wrapper to drop, becomes an empty statement (`;`) instead, which is valid in every statement position but reads a little oddly — a rare shape, left for a human to tidy. - **The flag's enum member is removed only when no reference to `Enum.MEMBER` survives substitution in that file** (exposure logging, a lookup table, or any use this codemod doesn't recognize as a gate read keeps the member). This check is same-file only — the semantic provider does not track enum-member references cross-file, so a member used exclusively from another file is not verified; treat enum-member removal as best-effort outside the defining file's own usages. - **Const-param removal accounts for aliased/renamed imports in its unanimity check** — if a call site is reached only through `import { f as g }`, the semantic reference count and the name-based call count disagree, and the param is kept rather than removed out from under a caller `references()` found but the textual scan couldn't see. - **Const-param body-inlining checks for nested shadows** — a param removed from a signature is only inlined into the body when no inner scope (a nested function/arrow param, a nested destructure, a local `const`/`let`) reuses the same name; otherwise the whole removal is skipped. - **Malformed `--param` values error instead of silently defaulting.** `value`/`removeOrphans`/`inlineWrappers`/`removeConstParams` must be `true`/`false` (string or boolean) when present — an unrecognized value (e.g. `value=False`) throws rather than silently taking the default, which for `value` would otherwise invert the rollout and delete the live branch. Likewise, `--param flag=` (present but empty) throws — only a fully absent `flag` (as under `jssg test`, which can't pass params) enters test mode. - **Constant-param removal is opt-in and narrowly scoped.** With `removeConstParams=true`, an object-property or single positional param of a **free function** is removed only when it was fed a non-literal originally (the flag made it constant) **and** every call site passes the same literal. Left for a human: **methods** (`svc.m(…)`) and **default-exported functions** — the semantic provider can't resolve `svc.method` or `export default fn` back to a definition, so these are skipped rather than half-edited. Also skipped: multi-arg positional calls, named (non-inline) param types, params with defaults, and object spreads. (Note: a chain blocked by one of these — e.g. a positional callee whose other caller sits inside a default-exported wrapper — stays put, since that call site never becomes a literal.) - **It never changes behavior.** The removed param was already passed the same literal everywhere; that literal is inlined into the body, so the function computes exactly what it did before. The only edge risk is an incomplete call-site graph (dynamic/re-exported calls `references()` can't see) leaving a stale `{ x: true }` — a **compile error** caught by `tsc`, never a silent runtime change. Run on a clean branch and typecheck after. - **Recursion is safe.** A function that forwards the param into its own (direct or indirect) recursive call passes a non-literal there, so unanimity fails and the param is **kept** — no infinite loop (a per-symbol `done` set plus `maxParamRounds` bound the work). Depth is capped by `maxParamRounds`; re-running the codemod does **not** go deeper (the flag is already gone, so nothing re-triggers) — raise `maxParamRounds` instead. ## Development ```bash pnpm test # fixtures incl. cross-file (tests/wrapper-inline/{input,expected}/) pnpm test:update # regenerate expected outputs pnpm check-types # type-check the transform ``` Fixtures cover the transforms and — just as important — the safety boundaries: | fixture | asserts | |---|---| | `backend-if-else`, `backend-early-return`, `expressions` | branch / ternary / `&&`\|`\|\|` folding | | `frontend-hook` | `useGateValue` + JSX ternary | | `promise-all` | destructure propagation + single-element collapse | | `promise-all-multi` | **multi-element `Promise.all` is re-aligned, NOT collapsed** | | `promise-allsettled` | `allSettled` inner call substituted, destructure **left intact** | | `logical-asymmetry` | `flag && x` → `x`, but `x && flag` → `x && true` (**no side effect dropped**) | | `orphan-helpers` | orphan removal, exported symbols preserved | | `enum-member` | enum member removed, siblings kept | | `wrapper-inline` | cross-file wrapper inlined + removed | | `wrapper-value-use` | wrapper referenced as a **value** is left intact | | `const-param` | always-constant object-property param removed cross-file (opt-in) | | `const-param-shorthand` | flag passed via object shorthand `{ prop }` is still detected + removed | | `const-param-positional` | single positional param `f(true)` → `f()` (arrow-const def) | | `const-param-transitive` | removal chases the chain `a → b → c` through forwarded params | | `const-param-recursion` | direct recursion (forwarded param) → **kept**, no loop | | `const-param-recursion-indirect` | indirect recursion `a ↔ b` → **kept**, no loop | | `const-param-not-unanimous` | param **kept** when a call site passes a different value | | `negative-other-flag` | an unrelated flag is left byte-identical | | `regression-shadow-destructure` | flag var name colliding with an array-destructure binding in another scope is **not** inlined | | `regression-exported-const` | an unrelated `export const` in a flag-touched file is left alone | | `regression-else-if-noelse` | a false `if` with no `else`, itself in an `else if` slot, is removed cleanly (the whole `else` clause drops, not left as `else ;`) | | `regression-else-if-chain` | a false `else if` in the MIDDLE of a longer chain is excised, reconnecting the surrounding branches | | `regression-enum-surviving-ref` | enum member with a surviving same-file reference is **kept** | | `regression-typeof-query` | a `typeof x` type query blocks inlining of `x` entirely | | `regression-const-param-shadow` | const-param body-inline **aborts** when an inner scope shadows the param name | | `regression-const-param-alias` | const-param removal **aborts** when a call site is reached only via an aliased import | | `regression-multi-wrapper-same-caller` | two wrappers in one file, both called from the same external file, compose correctly in one run | Tests use `--strictness ast`, so `expected` files are written clean — comparison ignores whitespace residue.
