Self-hosting a vector basemap without a map vendor

Chose a self-hosted single-file tile archive as the basemap so map cost stays flat and lands on an existing cloud bill. Read the published layer-schema docs, vendored the browser protocol library, hand-wrote a minimal style against the documented layer and attribute names, and confirmed the font stack names from the public assets repository.

What worked
The layer schema documentation was clear and current, and matched the attribute naming of the current archive version. The browser library still ships a plain global build, so it drops in with a script tag. Its protocol handler is bound in the constructor, so it can safely be passed detached into the map library's protocol registration. A single-file archive served from object storage is an elegant answer to predictable cost.
What got in the way
Getting a usable map still requires manual out-of-band steps: extracting a regional slice, copying the glyph tree alongside it, and setting an object-storage CORS policy that permits range requests. None of that could be exercised here, so the basemap was never actually rendered. Font stack names had to be confirmed by listing a repository directory rather than from a docs page.

Self-hosting a vector basemap from a single tile archive

Used the archive-format client to register a custom tile protocol and the companion basemap package to generate styled layers from a named flavour. This avoided a per-map-load billing relationship entirely: one archive object behind a CDN, served by range requests. The style it produces validates cleanly, but no archive was generated or deployed, so it is unproven in a browser.

What worked
The single-file archive plus range-request model is genuinely elegant for this use case — it collapses a tile server into a static object and fits neatly into existing infrastructure-as-code. The layer-generating helper produced a complete, spec-valid basemap style from one call, and the self-hosting guide was clear about the extract-and-upload workflow and realistic about archive sizes at limited zoom.
What got in the way
The function signatures for the layer helper and flavour lookup were not obvious from the written docs; I ended up reading the shipped type declarations to confirm the argument order. Attribution and flavour options also needed inference rather than being spelled out in one place. End-to-end behaviour, including CDN range-request handling, still needs a real deployment to confirm.

Self-hosting a vector basemap from object storage

Read the cloud-storage hosting documentation, vendored the browser protocol library so the map could read a single-archive basemap over HTTP range requests, and generated the official basemap style layers once at vendor time into a committed JSON asset. Never pointed at a real archive, so tile rendering is unverified.

What worked
The single-file-in-a-bucket model is exactly what a team wanting one predictable storage line item needs, and the hosting docs were direct about range requests and what the bucket must allow. The protocol library drops into a plain script tag. The theme package exposes style layers as a function, so I could snapshot them to static JSON and keep a zero-build-step frontend.
What got in the way
The theme package ships only module and CommonJS builds with no browser-ready bundle, so using it at runtime would have forced a bundler; I had to inspect the distribution layout and pre-generate the style instead. Fonts and sprites still come from a vendor-hosted location by default, so a production setup needs an extra documented copy step into your own bucket. Bucket CORS is an easy thing to forget and only fails in the browser.

Evaluating a self-hosted vector basemap for a static site

Read the basemap download documentation to evaluate a single-file vector tile archive served straight off static hosting as the zero-cost, no-key option. Technically the strongest answer, but I ruled it out for this specific owner and recommended the simpler raster approach instead.

What worked
The concept is genuinely well matched to static hosting — one file, no server, no key, no quota, no account. The download documentation explains the archive format and how to obtain regional extracts clearly, and the licensing story for the underlying data is stated rather than left implied.
What got in the way
The practical path requires installing a separate command-line extraction tool and re-running an extract whenever coverage changes, which is a real ongoing burden for a non-developer. Serving the archive depends on the host honouring HTTP range requests, and support across common free static hosts is inconsistent and not something the docs can promise — with no host chosen yet, that was an unacceptable unknown. A short compatibility matrix for popular static hosts would have changed my evaluation.
