* **Configuration Design:** Aim for simplicity with sensible defaults, while allowing for advanced customization.
* **Embedded Systems Optimization:** ESPHome targets resource-constrained microcontrollers. Be mindful of flash size and RAM usage.
**Why Heap Allocation Matters:**
ESP devices run for months with small heaps shared between Wi-Fi, BLE, LWIP, and application code. Over time, repeated allocations of different sizes fragment the heap. Failures happen when the largest contiguous block shrinks, even if total free heap is still large. We have seen field crashes caused by this.
**Heap allocation after `setup()` should be avoided unless absolutely unavoidable.** Every allocation/deallocation cycle contributes to fragmentation. ESPHome treats runtime heap allocation as a long-term reliability bug, not a performance issue. Helpers that hide allocation (`std::string`, `std::to_string`, string-returning helpers) are being deprecated and replaced with buffer and view based APIs.
**STL Container Guidelines:**
ESPHome runs on embedded systems with limited resources. Choose containers carefully:

StaticVector<ServiceRecord, MAX_SERVICES> services; // Allocates all MAX_SERVICES on stack
services.push_back(record1); // Tracks count but all slots allocated
// Good - compile-time fixed size, no dynamic allocation
StaticVector<ServiceRecord, MAX_SERVICES> services;
services.push_back(record1);

Use `cg.add_define("MAX_SERVICES", count)` to set the size from Python configuration.

```
Linear search on small datasets (1-16 elements) is often faster than hashing/tree overhead, but this depends on lookup frequency and access patterns. For frequent lookups in hot code paths, the O(1) vs O(n) complexity difference may still matter even for small datasets. `std::vector` with simple structs is usually fine—it's the heavy containers (`map`, `set`, `unordered_map`) that should be avoided for small datasets unless profiling shows otherwise.
5. **Detection:** Look for these patterns in compiler output:
5. **Avoid `std::deque`:** It allocates in 512-byte blocks regardless of element size, guaranteeing at least 512 bytes of RAM usage immediately. This is a major source of crashes on memory-constrained devices.
6. **Detection:** Look for these patterns in compiler output:
- Large code sections with STL symbols (vector, map, set)
- `alloc`, `realloc`, `dealloc` in symbol names
- `_M_realloc_insert`, `_M_default_append` (vector reallocation)
- Red-black tree code (`rb_tree`, `_Rb_tree`)
- Hash table infrastructure (`unordered_map`, `hash`)
**When to optimize:**
**Prioritize optimization effort for:**
- Core components (API, network, logger)
- Widely-used components (mdns, wifi, ble)
- Components causing flash size complaints
**When not to optimize:**
- Single-use niche components
- Code where readability matters more than bytes
- Already using appropriate containers
Note: Avoiding heap allocation after `setup()` is always required regardless of component type. The prioritization above is about the effort spent on container optimization (e.g., migrating from `std::vector` to `StaticVector`).
* **State Management:** Use `CORE.data` for component state that needs to persist during configuration generation. Avoid module-level mutable globals.
