A Modified TypeScript implementation of the PMTiles library. It is backwards compatible but offers support for the S2 Projection.
For now this spec supports deflating metadata/directories inside the browser, but it will be removed in the future.
#bun

# pnpm
pnpm add s2-pmtiles
# yarn
yarn add s2-pmtiles

cargo install s2-pmtilesimport { PMTilesReader, PMTilesWriter } from 's2-pmtiles'
// The File Reader you can run on bun/node/deno
const testFixture1 = new PMTilesReader(`test/fixtures/test_fixture_1.pmtiles`);
// get an WM tile
let x = 0;
let y = 0;
let z = 0;
let face = 0;
testFixture1.getTile(x, y, z); // undefied | Uint8Array
// get an S2 tile
testFixture1.getTileS2(face, x, y, z); // undefined | Uint8Array
// The File Writer you can run on bun/node/deno
const testFixture2 = new PMTilesWriter(`tmpFile.pmtiles`);
// write a tile
testFixture2.writeTileXYZ(x, y, z, Uint8Array.from([]));
// write an S2 tile
testFixture2.writeTileS2(face, x, y, z, Uint8Array.from([]));
// when you finish you commit to build the metadata
testFixture2.commit();
// The File Reader you can run in the browser
import { S2PMTilesReader } from 's2-pmtiles/browser';
// you want to add a true after the path for generic PMTiles, as it ensures 206 byte requests.
const browserFixture = new S2PMTilesReader(`https://www.example.com/test.pmtiles`, true);
// get an WM tile
browserFixture.getTile(x, y, z); // undefied | Uint8Array
// get an S2 tile
browserFixture.getTileS2(face, x, y, z); // undefined | Uint8ArraySome tsconfigs might need some extra help to see the s2-pmtiles/browser package.
To fix this update your tsconfig.json with the following:
{
"compilerOptions": {
"baseUrl": "./",
"paths": {
"s2-pmtiles/browser": ["./node_modules/s2-pmtiles/dist/browser.d.ts"]
}
}
}You need the tool tarpaulin to generate the coverage report. Install it using the following command:
cargo install cargo-tarpaulinThe bacon coverage tool is used to generate the coverage report. To utilize the pycobertura package for a prettier coverage report, install it using the following command:
pip install pycoberturaTo run the tests, use the following command:
# TYPESCRIPT
## basic test
bun run test
## live testing
bun run test:dev
# RUST
## basic test
cargo test
# live testing
bacon testTo generate the coverage report, use the following command:
cargo tarpaulin
# bacon
bacon coverage # or type `l` inside the tool
