TilerFactory

✓ from titiler.application import TilerFactory

✗ from titiler.application import TilerFactory

Minimal FastAPI app with COG and multi-band tiler endpoints.

from fastapi import FastAPI from titiler.application import TilerFactory from titiler.core.factory import MultiBandTilerFactory from titiler.core.resources.enums import ImageType app = FastAPI() # COG tiler with default settings cog_tiler = TilerFactory() app.include_router(cog_tiler.router, prefix="/cog") # Multi-band tiler multi_tiler = MultiBandTilerFactory() app.include_router(multi_tiler.router, prefix="/multi") # Optional: enable CORS from titiler.core.middleware import CORSMiddleware app.add_middleware(CORSMiddleware, allow_origins=["*"])

Debug

Known issues

breakingIn v2.0.0, the default TilerFactory no longer auto-includes all endpoints. You must explicitly add routers or configure settings.

fix

Review the new factory pattern: use TilerFactory() and .include_router() explicitly.

affects: >=2.0.0

deprecatedThe titiler.mosaic metapackage is deprecated; use titiler-application directly.

fix

Install titiler-application instead of titiler.mosaic.

affects: >=1.2.0

gotchaWhen deploying with AWS Lambda, you must set CPYTHON_GC_RETAIN to avoid memory issues with GDAL.

fix

Set environment variable CPYTHON_GC_RETAIN=1 in Lambda configuration.

affects: all

gotchaIn v2, the 'assets' parameter is required for STAC and mosaic endpoints; use 'assets=:all:' to select all bands.

fix

Always provide assets parameter, e.g., assets=:all:.

affects: >=2.0.0
