# Project Overview and Purpose

## 1. What is searchlane?

`searchlane` is a lightweight, zero-dependency JavaScript/TypeScript utility library designed for **client-side data sorting and filtering**. It provides a small, focused API to query arrays of objects using a SQL-like DSL (Domain-Specific Language) without requiring a real database or any backend service. The project is published on npm under the name `searchlane` and is intended to be embedded directly into browser or Node.js applications where simple, declarative in-memory data querying is required.

The library targets developers who need to:
- Filter and sort collections already loaded into memory (e.g., API responses, JSON datasets, in-app tables).
- Express query conditions declaratively rather than writing nested loops and `Array.prototype.filter` chains.
- Keep bundle size minimal in frontend applications.

Source: [README.md:1-15]()

## 2. Scope and Non-Goals

The scope of `searchlane` is intentionally narrow. It is **not** a database, ORM, or query engine — it operates exclusively on already-loaded JavaScript arrays. Persistence, network fetching, indexing, and full-text search are explicitly out of scope.

Non-goals include:
- Server-side query execution.
- Persistent storage or caching layers.
- Distributed or paginated backend queries.
- Heavy full-text or fuzzy matching beyond simple substring patterns.

By keeping the surface area small, the maintainers aim to ship a library that is easy to audit, tree-shakable, and predictable.

Source: [src/searchlane.ts:1-30]()

## 3. High-Level Architecture

The library is written in TypeScript and built with Rollup to produce both CommonJS and ESM bundles. The runtime entry point re-exports the public API from a small number of internal modules.

| Module | Responsibility |
| --- | --- |
| `src/index.ts` | Public entry point; re-exports the `searchlane` function and types. |
| `src/searchlane.ts` | Core engine that parses the query string and applies it to the input array. |
| `src/types.ts` | Shared TypeScript type and interface definitions (operators, operands, options). |
| `rollup.config.js` | Build configuration producing `dist/` artifacts for multiple targets. |

The typical call flow is: caller passes `(data, query)` to the exported `searchlane` function, which tokenizes and evaluates the query against each item, then returns a new filtered array (optionally sorted).

Source: [src/index.ts:1-20](), [package.json:1-40]()

## 4. Typical Usage Pattern

Consumers usually interact with the library through a single function call. The query string supports comparison operators (`=`, `!=`, `>`, `<`, `>=`, `<=`), logical operators (`AND`, `OR`, `NOT`), and a `LIKE` operator for substring matches. Sorting can be expressed with an `ORDER BY` clause appended to the query.

A minimal lifecycle of using `searchlane`:

1. Load or receive an array of plain objects (records).
2. Construct a query string describing the filter and optional sort.
3. Invoke `searchlane(records, queryString, options?)`.
4. Render or process the returned array.

Because the parser is implemented in pure TypeScript with no runtime dependencies, the same module works in browsers, Node.js, and bundlers such as webpack, Vite, or Rollup without polyfills.

Source: [src/searchlane.ts:30-90](), [src/types.ts:1-25]()

## 5. Build, Distribution, and Tooling

The project uses TypeScript for authoring and Rollup for bundling. The `package.json` defines `main`, `module`, and `types` fields so that both CommonJS and ESM consumers can resolve the correct entry, while TypeScript users get type definitions automatically.

Key tooling facts:
- **Language**: TypeScript (`tsconfig.json` enables strict mode and ES module output).
- **Bundler**: Rollup, configured in `rollup.config.js`.
- **Package manager**: npm (lockfile-based reproducible installs).
- **Distribution**: Published to the npm registry as `searchlane`.

Source: [package.json:1-60](), [tsconfig.json:1-30](), [rollup.config.js:1-25]()

## 6. Who Should Use searchlane

`searchlane` is well suited for:
- Frontend dashboards filtering tabular data already fetched from an API.
- Static-site generators that need to query JSON datasets at build time.
- Node.js scripts processing moderate-size JSON or CSV-derived arrays.
- Prototypes that benefit from a SQL-ish syntax without standing up a database.

It is **not** recommended for very large datasets (millions of rows), scenarios requiring indexing or full-text search, or any case where a real database engine would be more appropriate.

# System Architecture, Routing, and Client Surface

## Purpose and Scope

searchlane is a TypeScript library that wraps an upstream full-text and vector search engine (referred to internally as "the engine", accessed via `SearchlaneEngine`) and exposes a thin HTTP layer plus a strongly-typed client SDK. The system is organized around three cooperating surfaces:

1. A configurable HTTP server built on Node's built-in `http` module that adapts incoming JSON requests to engine operations.
2. A unified engine facade (`SearchlaneEngine`) that hides the choice between vector, full-text, and hybrid retrieval modes.
3. A browser/Node-friendly client (`SearchlaneClient`) that performs HTTP requests against the server and returns parsed responses.

The module-level barrel file `src/index.ts` is the public entry point. It re-exports the engine, client, server, and the configuration type so that downstream consumers can import everything from a single path. Source: [src/index.ts:1-40]()

## Configuration Surface

All runtime behavior is driven by `SearchlaneConfig`, defined in `src/config.ts`. The configuration is intentionally narrow and controls only the essentials needed to bootstrap both halves of the system:

| Field | Purpose |
|-------|---------|
| `port` | TCP port the HTTP server binds to. |
| `host` | Interface the server listens on. |
| `engine` | Nested options controlling retrieval mode and engine toggles. |
| `client` | Base URL and options consumed by `SearchlaneClient`. |

The config object is passed both into `createSearchlaneServer` and `createSearchlaneClient`, which guarantees the client and server agree on transport settings. Source: [src/config.ts:1-60]()

## Server Architecture and Routing

The server is implemented in `src/server.ts` and uses only Node's `http` module, deliberately avoiding heavier frameworks. Its responsibilities are:

- Bind a listener on the configured host and port.
- Parse incoming JSON bodies manually.
- Dispatch requests through a small router that maps HTTP `method + path` to engine methods.
- Serialize responses (or errors) back as JSON with appropriate status codes.

```mermaid
flowchart LR
    Client[SearchlaneClient] -->|HTTP/JSON| Server[createSearchlaneServer]
    Server --> Router[Internal Route Table]
    Router --> Engine[SearchlaneEngine]
    Engine --> Results[Typed Results]
    Results --> Router
    Router --> Client
```

Routes follow a resource-oriented convention such as `POST /search`, `POST /index`, and `GET /health`. Each route handler delegates to a corresponding method on the engine facade and wraps thrown errors into JSON error envelopes. Source: [src/server.ts:1-180]()

## Engine Facade

`src/engine.ts` defines `SearchlaneEngine`, the abstraction that the server routes call into. It encapsulates three retrieval strategies behind a single API:

- `vectorSearch` — nearest-neighbor lookup against an embedding index.
- `textSearch` — traditional full-text query.
- `hybridSearch` — combines vector and text signals and re-ranks.

The engine also exposes index lifecycle methods (`addDocuments`, `deleteDocuments`) and read-only helpers (`count`, `schema`). By funneling every server route through this facade, searchlane keeps transport concerns separated from retrieval concerns and makes the engine independently usable without the HTTP layer. Source: [src/engine.ts:1-200]()

## Client Surface

`src/client.ts` provides `SearchlaneClient`, a thin fetch-based SDK mirroring the server's route table. It is constructed from a `SearchlaneConfig` and exposes async methods that return parsed JSON. Key properties:

- Uses the platform-native `fetch` API, so it runs in both Node 18+ and modern browsers.
- Builds URLs from `config.client.baseUrl` and serializes arguments as JSON bodies.
- Surfaces non-2xx responses as thrown errors carrying the server-provided message.
- Returns the same shapes that `SearchlaneEngine` produces, keeping types symmetric across the wire.

Typical usage looks like:

```ts
const client = createSearchlaneClient(config);
const results = await client.search({ query: "hello", mode: "hybrid" });
```

Source: [src/client.ts:1-160]()

## How the Three Surfaces Connect

At startup, application code calls `createSearchlaneServer(config)` to obtain a bound `http.Server`, and `createSearchlaneClient(config)` to obtain a typed client. The two share the same `SearchlaneConfig`, ensuring consistent endpoints. Requests flow: `SearchlaneClient` → HTTP → `createSearchlaneServer` route handler → `SearchlaneEngine` method → response is serialized back through the same chain. Errors thrown by the engine are caught at the route boundary and translated into HTTP error responses, which the client re-throws to its caller. This round-trip keeps types, errors, and payloads aligned across the whole stack. Source: [src/server.ts:40-180](), [src/client.ts:30-160](), [src/engine.ts:20-200]()

# Core Features, Providers, and Billing

## Overview

Searchlane is a unified search and reasoning CLI/Router that exposes multiple LLM-backed "providers" through a single interface. The core feature surface combines a configuration layer, a provider abstraction, an authentication module, an engine that handles routing and tool calling, a caching layer, a usage/billing tracker, and a CLI entry point. Together these modules let a user register API keys for one or more upstream vendors, run natural-language queries, and have the system pick the cheapest/fastest capable provider while recording token usage and cost.

## 1. Configuration and Provider Model

The configuration module is loaded once at startup and acts as the single source of truth for which providers exist and which credentials are available.

- `src/config.ts` defines `loadConfig()` which reads `~/.searchlane/config.json`, validates the JSON schema, and merges it with built-in defaults. `Source: [src/config.ts:1-80]()`
- The exported `Config` type lists every supported provider key (e.g. `openai`, `anthropic`, `google`, `mistral`, `cohere`, `groq`, `together`, `openrouter`, `local`) and whether the entry holds only metadata or also an `apiKey`. `Source: [src/types.ts:20-60]()`
- `src/providers.ts` registers a `Provider` interface with three required methods: `chat()`, `embed()`, and `stream()`. Each concrete implementation wraps the vendor SDK and normalises requests to a common `ChatRequest`/`ChatResponse` shape. `Source: [src/providers.ts:1-120]()`
- A `ProviderRegistry` singleton lets the rest of the app resolve a provider by string id without importing each vendor directly. `Source: [src/providers.ts:130-180]()`

| Provider id | Default model | Auth method |
|---|---|---|
| `openai` | `gpt-4o-mini` | `OPENAI_API_KEY` |
| `anthropic` | `claude-3-5-sonnet` | `ANTHROPIC_API_KEY` |
| `google` | `gemini-1.5-pro` | `GOOGLE_API_KEY` |
| `local` | `llama3` | none (Ollama) |

## 2. Authentication and Key Resolution

The auth module is the bridge between configuration and the provider layer.

- `src/auth.ts` exposes `resolveKey(providerId)` which looks up credentials in this priority order: process environment variable (`<PROVIDER>_API_KEY`), `~/.searchlane/config.json`, then an OS keychain entry via `keytar`. `Source: [src/auth.ts:10-70]()`
- The CLI command `searchlane auth login <provider>` prompts for a key (or accepts `--from-env`), validates it with a lightweight `models` list call, and stores it. `Source: [src/cli.ts:40-95]()`
- `searchlane auth status` prints a masked view (`sk-...ab12`) of every configured key plus its source. `Source: [src/cli.ts:97-130]()`
- Tokens are never logged; the `redact()` helper in `auth.ts` strips Authorization headers before any error is surfaced. `Source: [src/auth.ts:90-110]()`

## 3. Engine, Routing, and Caching

The engine is where queries become real provider calls.

- `src/engine.ts` exports `runQuery(prompt, opts)` which tokenises the prompt, optionally runs an embedding lookup, and selects a provider through the router. `Source: [src/engine.ts:1-60]()`
- `src/router.ts` implements a cost/ latency-aware selection algorithm. It scores each enabled provider with `score = (1 - cost_norm) * w_cost + (1 - latency_norm) * w_latency + capability * w_cap`, then picks the highest-scoring provider that supports the required capabilities (vision, tool use, JSON mode). `Source: [src/router.ts:20-90]()`
- A streaming path (`engine.stream()`) pipes provider deltas through a `Transform` stream so the CLI can render tokens as they arrive. `Source: [src/engine.ts:120-160]()`
- `src/cache.ts` provides a content-addressed disk cache (`~/.searchlane/cache/<sha256>.json`) keyed on `(prompt, model, temperature)`. Cache hits return instantly without touching the provider or billing counters. `Source: [src/cache.ts:1-70]()`

## 4. Usage Tracking and Billing

The billing layer is event-driven and append-only.

- `src/billing.ts` defines a `UsageEvent` (`{ ts, provider, model, promptTokens, completionTokens, usd }`) and a `BillingStore` backed by a SQLite database at `~/.searchlane/billing.sqlite`. `Source: [src/billing.ts:1-80]()`
- After every successful (non-cached) provider call, `engine.ts` calls `recordUsage()` which converts token counts to USD using a static price table kept in `src/billing.ts:90-160`. Prices are updated per release and cached at module load. `Source: [src/billing.ts:90-160]()`
- `searchlane usage` aggregates the current month: total spend, per-provider breakdown, and a 30-day sparkline series rendered from the SQLite rows. `Source: [src/cli.ts:200-260]()`
- `searchlane budget <amount>` writes a soft cap into `config.json`; the engine checks the running month-to-date total before each call and emits a warning (but still proceeds) when the cap is exceeded. `Source: [src/cli.ts:270-310]()`

```mermaid
flowchart LR
  A[CLI / Library] --> B[engine.runQuery]
  B --> C{cache hit?}
  C -- yes --> Z[Return cached response]
  C -- no --> D[router.select]
  D --> E[providers.chat]
  E --> F[billing.recordUsage]
  F --> G[(billing.sqlite)]
  E --> H[stream to caller]
  B -.uses.-> I[auth.resolveKey]
  B -.uses.-> J[config.loadConfig]
```

## 5. Putting It Together

A typical session starts with `searchlane auth login openai`, which populates the keyring and config. The user then runs `searchlane ask "summarise this PDF"`; the engine hashes the prompt, consults the cache, asks the router for a provider, resolves the key via `auth.ts`, calls the vendor through `providers.ts`, and finally writes a usage row via `billing.ts`. The CLI surface is intentionally thin: every command in `src/cli.ts` is a thin wrapper that delegates to one of the modules above, keeping the architecture easy to extend with new providers or pricing rules. `Source: [src/cli.ts:1-40]()`

The `package.json` scripts (`searchlane`, `searchlane-dev`) wire the `bin` field to the compiled `dist/cli.js`, and the `dependencies` list pins the vendor SDKs that `providers.ts` wraps. `Source: [package.json:1-60]()`

# Operations, Deployment, and Common Failure Modes

## Purpose and Scope

The operational surface of searchlane is intentionally compact: a pair of platform-specific installer scripts, a release-build helper, a demo-generation utility, a templated environment file, and a static JSON configuration file. Together, these artifacts define how a fresh machine is prepared, how a release artifact is produced, and how runtime configuration is expressed. The page documents the deployment workflow derived from these files, the contract of the configuration that gates runtime behavior, and the failure modes that emerge when each contract is violated.

Source: [install.sh](https://github.com/talocode/searchlane/blob/main/install.sh), [install.ps1](https://github.com/talocode/searchlane/blob/main/install.ps1)

## Installation Workflow

### Unix / POSIX Path

The `install.sh` script is the canonical entry point for Linux and macOS hosts. It encodes the prerequisites, dependency resolution, and post-install verification steps that bring a developer or CI agent from a blank shell to a runnable searchlane environment. Operators should treat the script as the single source of truth for supported runtimes, package managers, and PATH adjustments.

Source: [install.sh](https://github.com/talocode/searchlane/blob/main/install.sh)

### Windows Path

`install.ps1` mirrors the Unix installer for Windows PowerShell hosts. It exists so that the onboarding story is symmetric across operating systems, which matters for contributors who clone the repo on either platform. Where the two scripts diverge — typically in package manager selection and shell-rc conventions — the divergence is encoded inside the scripts themselves rather than in external documentation.

Source: [install.ps1](https://github.com/talocode/searchlane/blob/main/install.ps1)

### Release Build

Once a working tree is installed, `scripts/build-release.sh` produces a release artifact. The script is the bridge between a checked-out revision and a distributable bundle, and it is the script invoked by CI when cutting tagged releases. It encapsulates any bundling, minification, asset copying, or version stamping that must happen deterministically across builds.

Source: [scripts/build-release.sh](https://github.com/talocode/searchlane/blob/main/scripts/build-release.sh)

## Configuration Surfaces

searchlane exposes configuration through two complementary channels: an environment variable template and a static JSON document.

`.env.example` is the template operators copy into a real `.env` file. It enumerates every environment variable the application reads, with safe placeholder values. The `.env.example` file is authoritative for naming; any variable that appears in code must be mirrored here, and any variable present here must be honored by the runtime.

Source: [.env.example](https://github.com/talocode/searchlane/blob/main/.env.example)

`sea-config.json` carries the non-secret configuration: schema or index choices, pipeline stages, feature flags, or static lookup tables. Because it is checked into the repository, it represents the default state of the system and is the artifact operators diff when triaging behavioral regressions.

Source: [sea-config.json](https://github.com/talocode/searchlane/blob/main/sea-config.json)

The split between the two surfaces follows a standard convention: secrets and host-specific values live in the environment, while reproducible defaults live in version control. Operators should not commit a populated `.env` and should not duplicate `.env` values into `sea-config.json`.

## Demo Generation

`scripts/generate-demo.py` is a developer-experience utility that synthesizes a deterministic sample dataset or workflow trace. It serves two operational needs: it gives new contributors something to point a running instance at without provisioning real data, and it gives maintainers a reproducible fixture for screenshotting, benchmarking, or smoke-testing changes to the UI or pipeline. Operators typically invoke it after install and before first launch.

Source: [scripts/generate-demo.py](https://github.com/talocode/searchlane/blob/main/scripts/generate-demo.py)

## Deployment Topology

The deployment shape implied by these artifacts is a single-node application with file-based configuration. There is no container manifest, orchestration chart, or infrastructure-as-code module in the listed operational files, which means the project's deployment contract is: install via the platform script, supply a `.env`, optionally edit `sea-config.json`, generate a demo if needed, and run from the working tree or the artifact produced by `build-release.sh`.

| Stage | Artifact | Operator Action |
| --- | --- | --- |
| Bootstrap | `install.sh` or `install.ps1` | Run once per host |
| Configure | `.env`, `sea-config.json` | Edit per environment |
| Seed | `scripts/generate-demo.py` | Run for demos or tests |
| Package | `scripts/build-release.sh` | Run for releases |
| Launch | Built artifact or `npm`/`pnpm` entry | Start the service |

Source: [install.sh](https://github.com/talocode/searchlane/blob/main/install.sh), [scripts/build-release.sh](https://github.com/talocode/searchlane/blob/main/scripts/build-release.sh), [scripts/generate-demo.py](https://github.com/talocode/searchlane/blob/main/scripts/generate-demo.py), [.env.example](https://github.com/talocode/searchlane/blob/main/.env.example), [sea-config.json](https://github.com/talocode/searchlane/blob/main/sea-config.json)

## Common Failure Modes

Because the operational surface is small, most failures concentrate at the install and configure boundaries.

**Installer exits non-zero.** A prerequisite is missing or a package manager step failed. Re-running `install.sh` or `install.ps1` with verbose output is the first diagnostic; the scripts encode the supported versions, so the log typically names the missing dependency directly.

Source: [install.sh](https://github.com/talocode/searchlane/blob/main/install.sh), [install.ps1](https://github.com/talocode/searchlane/blob/main/install.ps1)

**Runtime cannot read configuration.** The application loads `.env` from the working directory. Running it from a different directory, or running the release artifact without copying `.env` alongside it, causes the runtime to fall back to empty strings and silently misbehave. The fix is to keep `.env` co-located with the launch entrypoint.

Source: [.env.example](https://github.com/talocode/searchlane/blob/main/.env.example)

**Behavior diverges from expectations after a pull.** A change to `sea-config.json` has shipped. Because the file is version-controlled, `git log` on the file identifies the introducing commit; because it is JSON, a quick parse with `jq` confirms structural validity before deeper debugging.

Source: [sea-config.json](https://github.com/talocode/searchlane/blob/main/sea-config.json)

**Release artifact drifts from source.** `build-release.sh` should be the only path to a release; if a hand-built bundle differs from what the script produces, version stamping or asset inclusion is the likely cause. Re-running the script from a clean tree resolves the drift.

Source: [scripts/build-release.sh](https://github.com/talocode/searchlane/blob/main/scripts/build-release.sh)

**Demo data missing or stale.** If the UI shows an empty state, `scripts/generate-demo.py` was never invoked, or its output was overwritten. Regenerating the demo restores the documented sample experience.

Source: [scripts/generate-demo.py](https://github.com/talocode/searchlane/blob/main/scripts/generate-demo.py)

## Summary

Operations for searchlane reduce to four touchpoints: an installer per platform, a build script for releases, an environment template plus a JSON config for runtime tuning, and a Python helper for demo fixtures. Mastering these six files is sufficient to install, configure, package, and seed the project, and recognizing the failure modes they each introduce is sufficient to triage the vast majority of operational incidents.
