+# @hyperdx/cli Development Guide
+
+## What is @hyperdx/cli?
+
+A terminal CLI for searching, tailing, and inspecting logs and traces from
+HyperDX. It provides both an interactive TUI (built with Ink — React for
+terminals) and a non-interactive streaming mode for piping.
+
+The CLI connects to the HyperDX API server and queries ClickHouse directly
+through the API's `/clickhouse-proxy` endpoint, using the same query generation
+logic (`@hyperdx/common-utils`) as the web frontend.
+
+## CLI Commands
+
+```
+hdx tui -s <url>                    # Interactive TUI (main command)
+hdx stream -s <url> --source "Logs" # Non-interactive streaming to stdout
+hdx sources -s <url>                # List available sources
+hdx auth login -s <url>             # Sign in (interactive or -e/-p flags)
+hdx auth status                     # Show auth status (reads saved session)
+hdx auth logout                     # Clear saved session
+```
+
+The `-s, --server <url>` flag is required for commands that talk to the API. If
+omitted, the CLI falls back to the server URL saved in the session file from a
+previous `hdx auth login`.

+
+## Key Components
+
+### EventViewer (`components/EventViewer.tsx`)
+
+The main TUI component (~1100 lines). Handles:
+
+- **Table view**: Dynamic columns derived from query results, percentage-based
+  widths, `overflowX="hidden"` for truncation
+- **Search**: Lucene query via `/` key, submits on Enter
+- **Follow mode**: Slides time range forward every 2s, pauses when detail panel
+  is open, restores on close
+- **Detail panel**: Three tabs (Overview / Column Values / Trace), cycled via
+  Tab key. Detail search via `/` filters content within the active tab.
+- **Select editor**: `s` key opens `$EDITOR` with the current SELECT clause.
+  Custom selects are stored per source ID.
+- **State management**: ~20 `useState` hooks. Key states include `events`,
+  `expandedRow`, `detailTab`, `isFollowing`, `customSelectMap`,
+  `traceSelectedIndex`.
+
+### TraceWaterfall (`components/TraceWaterfall.tsx`)
+
+Port of the web frontend's `DBTraceWaterfallChart`. Key details:
+
+- **Tree building**: Single-pass DAG builder over time-sorted rows. Direct port
+  of the web frontend's logic — do NOT modify without checking
+  `DBTraceWaterfallChart` first.
+- **Correlated logs**: Fetches log events via `buildTraceLogsSql` and merges
+  them into the span tree (logs attach as children of the span with matching
+  SpanId, using `SpanId-log` suffix to avoid key collisions).
+- **j/k navigation**: `selectedIndex` + `onSelectedIndexChange` props controlled
+  by EventViewer. `effectiveIndex` falls back to `highlightHint` when no j/k
+  navigation has occurred.
+- **Event Details**: `SELECT *` fetch for the selected span/log, rendered via
+  the shared `ColumnValues` component. Uses stable scalar deps
+  (`selectedNodeSpanId`, `selectedNodeTimestamp`, `selectedNodeKind`) to avoid
+  infinite re-fetch loops.
+- **Duration formatting**: Dynamic units — `1.2s`, `3.5ms`, `45.2μs`, `123ns`.
+- **Highlight**: `inverse` on label and duration text for the selected row. Bar
+  color unchanged.
+
+### RowOverview (`components/RowOverview.tsx`)
+
+Port of the web frontend's `DBRowOverviewPanel`. Three sections:
+
+1. **Top Level Attributes**: Standard OTel fields (TraceId, SpanId, SpanName,
+   ServiceName, Duration, StatusCode, etc.)
+2. **Span/Log Attributes**: Flattened from `source.eventAttributesExpression`,
+   shown with key count header
+3. **Resource Attributes**: Flattened from
+   `source.resourceAttributesExpression`, rendered as chips with
+   `backgroundColor="#3a3a3a"` and cyan key / white value
+
+### ColumnValues (`components/ColumnValues.tsx`)
+
+Shared component for rendering key-value pairs from a row data object. Used by:
+
+- Column Values tab in the detail panel
+- Event Details section in the Trace tab's waterfall
+
+Supports `searchQuery` filtering and `wrapLines` toggle.
+
+## Web Frontend Alignment
+
+This package mirrors several web frontend components. **Always check the
+corresponding web component before making changes** to ensure behavior stays
+consistent:
+
+| CLI Component    | Web Component           | Notes                            |
+| ---------------- | ----------------------- | -------------------------------- |
+| `TraceWaterfall` | `DBTraceWaterfallChart` | Tree builder is a direct port    |
+| `RowOverview`    | `DBRowOverviewPanel`    | Same sections and field list     |
+| Trace tab logic  | `DBTracePanel`          | Source resolution (trace/log)    |
+| Detail panel     | `DBRowSidePanel`        | Tab structure, highlight hint    |
+| Event query      | `DBTraceWaterfallChart` | `getConfig()` → `buildTrace*Sql` |
+
+Key expression mappings from the web frontend's `getConfig()`:
+
+- `Timestamp` → `displayedTimestampValueExpression` (NOT
+  `timestampValueExpression`)
+- `Duration` → `durationExpression` (raw, not seconds like web frontend)
+- `Body` → `bodyExpression` (logs) or `spanNameExpression` (traces)
+- `SpanId` → `spanIdExpression`
+- `ParentSpanId` → `parentSpanIdExpression` (traces only)
+
+## Keybindings (TUI mode)
+
+| Key           | Action                                     |
+| ------------- | ------------------------------------------ |
+| `j` / `↓`     | Move selection down                        |
+| `k` / `↑`     | Move selection up                          |
+| `l` / `Enter` | Expand row detail                          |
+| `h` / `Esc`   | Close detail / blur search                 |
+| `G`           | Jump to newest                             |
+| `g`           | Jump to oldest                             |
+| `/`           | Search (global in table, filter in detail) |
+| `Tab`         | Cycle sources/searches or detail tabs      |
+| `Shift+Tab`   | Cycle backwards                            |
+| `s`           | Edit SELECT clause in $EDITOR              |
+| `t`           | Edit time range in $EDITOR                 |
+| `f`           | Toggle follow mode (live tail)             |
+| `w`           | Toggle line wrap                           |
+| `?`           | Toggle help screen                         |
+| `q`           | Quit                                       |
+
+In the **Trace tab**, `j`/`k` navigate spans/logs in the waterfall instead of
+the main table.
+
+## Development
+
+```bash
+# Run in dev mode (tsx, no compile step)
+cd packages/cli
+yarn dev tui -s http://localhost:8000
+
+# Type check
+npx tsc --noEmit
+
+# Bundle with tsup
+yarn build
+
+# Compile standalone binary (current platform)
+yarn compile
+
+# Cross-compile
+yarn compile:macos        # macOS ARM64
+yarn compile:macos-x64    # macOS x64
+yarn compile:linux        # Linux x64
+```
+
+## Key Patterns
+
+### Session Management
+
+Session is stored at `~/.config/hyperdx/cli/session.json` with mode `0o600`.
+Contains `apiUrl` and `cookies[]`. The `ApiClient` constructor loads the saved
+session and checks if the stored `apiUrl` matches the requested one.
+
+### ClickHouse Proxy Client
+
+`ProxyClickhouseClient` extends `BaseClickhouseClient` from common-utils. It:
+
+- Routes queries through `/clickhouse-proxy` (sets `pathname`)
+- Injects session cookies for auth
+- Passes `x-hyperdx-connection-id` header
+- Disables basic auth (`set_basic_auth_header: false`)
+- Forces `content-type: text/plain` to prevent Express body parser issues
+
+### Source Expressions
+
+Sources have many expression fields that map to ClickHouse column names. Key
+ones used in the CLI:
+
+- `timestampValueExpression` — Primary timestamp (often `TimestampTime`,
+  DateTime)
+- `displayedTimestampValueExpression` — High-precision timestamp (often
+  `Timestamp`, DateTime64 with nanoseconds). **Use this for waterfall queries.**
+- `traceIdExpression`, `spanIdExpression`, `parentSpanIdExpression`
+- `bodyExpression`, `spanNameExpression`, `serviceNameExpression`
+- `durationExpression` + `durationPrecision` (3=ms, 6=μs, 9=ns)
+- `eventAttributesExpression`, `resourceAttributesExpression`
+- `logSourceId`, `traceSourceId` — Correlated source IDs
+
+### useInput Handler Ordering
+
+The `useInput` callback in EventViewer has a specific priority order. **Do not
+reorder these checks**:
+
+1. `?` toggles help (except when search focused)
+2. Any key closes help when showing
+3. `focusDetailSearch` — consumes all keys except Esc/Enter
+4. `focusSearch` — consumes all keys except Tab/Esc
+5. Trace tab j/k — when detail panel open and Trace tab active
+6. General j/k, G/g, Enter/Esc, Tab, etc.
+7. Single-key shortcuts: `w`, `f`, `/`, `s`, `t`, `q`
+
+### Dynamic Table Columns
+
+When `customSelect` is set (via `s` key), columns are derived from the query
+result keys. Otherwise, hardcoded percentage-based columns are used per source
+kind. The `getDynamicColumns` function distributes 60% evenly among non-last
+columns, with the last column getting the remainder.
+
+### Follow Mode
+
+- Enabled by default on startup
+- Slides `timeRange` forward every 2s, triggering a replace fetch
+- **Paused** when detail panel opens (`wasFollowingRef` saves previous state)
+- **Restored** when detail panel closes
+
+### Custom Select Per Source
+
+`customSelectMap: Record<string, string>` stores custom SELECT overrides keyed
+by `source.id`. Each source remembers its own custom select independently.
