Key helpers

apiFetch(path, opts) — api.mjs

All HTTP calls to the OmniRoute server must go through this wrapper.

import { apiFetch } from "./api.mjs";

const res = await apiFetch("/api/health");
if (!res.ok) await res.assertOk(); // throws ApiError with mapped exit code
const data = await res.json();

Options:

• baseUrl — override base URL (default: OMNIROUTE_BASE_URL env or localhost:20128)
• apiKey — override API key (default: OMNIROUTE_API_KEY)
• method, body, headers — standard fetch options
• timeout — per-attempt ms (default: 30000)
• retry — false to disable (default: enabled)
• retryMax — total attempts (default: 3)
• verbose — log retry attempts to stderr

withRuntime(fn, opts) — runtime.mjs

Provides server-first / DB-fallback transparently.

import { withRuntime } from "./runtime.mjs";

await withRuntime(async (ctx) => {
  if (ctx.kind === "http") {
    const res = await ctx.api("/v1/providers");
    return res.json();
  }
  return ctx.db.prepare("SELECT * FROM provider_connections").all();
});

• opts.requireServer = true — throws ServerOfflineError (exit 3) if offline
• opts.preferDb = true — always use DB (skip server check)

t(key, vars) — i18n.mjs

Internationalized strings. Catalog loaded from locales/{locale}.json.

import { t } from "./i18n.mjs";

console.log(t("common.serverOffline"));
console.log(t("setup.testFailed", { error: err.message }));

Locale detection order: OMNIROUTE_LANG → LC_ALL → LC_MESSAGES → LANG → en.

emit(data, opts) — output.mjs

Format-aware output. Reads opts.output to select table/json/jsonl/csv.

import { emit, printError, EXIT_CODES } from "./output.mjs";

emit(providers, { output: opts.output ?? "table" });
printError("Something went wrong");
process.exit(EXIT_CODES.SERVER_OFFLINE);

Locale selection

The CLI displays text in the user's language. Detection order:

1. --lang <code> flag on the command line
2. OMNIROUTE_LANG environment variable
3. System env: LC_ALL → LC_MESSAGES → LANG
4. Fallback: en

Set permanently:

omniroute config lang set pt-BR       # saves to ~/.omniroute/.env
omniroute config lang list            # show all 42 available locales
omniroute config lang get             # show currently active locale

One-time override:

omniroute --lang de providers list    # run in German, not persisted
OMNIROUTE_LANG=ja omniroute status    # same effect via env

Adding a new locale: add entry to config/i18n.json, then run:

node bin/cli/scripts/generate-locales.mjs

Adding a new command

1. Create bin/cli/commands/your-command.mjs
2. Export registerYourCommand(program) following the Commander pattern
3. Register in bin/cli/commands/registry.mjs
4. Add strings to locales/en.json and locales/pt-BR.json
5. Write test in tests/unit/cli-your-command.test.ts

See CONVENTIONS.md for exit codes, flag naming, output format, and destructive-action rules.
