impact-map-endpoint

library1.2.0jsnpmunverified

A utility for determining TopoJSON endpoints for nodes in a rollup tree structure, used as a dependency within the 832 impact mapping framework. The current version is 1.2.0. It is a niche internal package with low release activity. Key differentiator: tightly coupled with the 832 project's rollup tree model for spatial data.

TypeScript type import

Shows basic usage to compute TopoJSON endpoint for a node in a rollup tree.

import impactMapEndpoint from 'impact-map-endpoint'; const endpoint = impactMapEndpoint({ node: { id: 'region', parent: null, children: ['subregion1', 'subregion2'] }, rollup: { regions: ['subregion1', 'subregion2'] } }); console.log(endpoint);

Debug

Known issues

breakingAPI changed in v1.0: output format changed from {endpoint: {...}} to flat object with coordinates property.

fix

Update consumer code to access endpoint.coordinates instead of endpoint.endpoint.coordinates.

affects: >=1.0

deprecatedOption 'tolerance' was deprecated in v1.0 and removed in v1.1.

fix

Remove tolerance option; no replacement.

affects: >=1.0

gotchaThe input rollup tree must be a flat object with node references; circular references cause infinite recursion.

fix

Ensure rollup tree has no circular references before passing to the function.

affects: >=0.5

Errors

Common errors & fixes

TypeError: Cannot read properties of undefined (reading 'children')

Node object missing 'children' property when parent is null.

fix

Ensure root node has children: [] even if no children.

Error: Unknown node type 'none'

Node has type property not recognized by the library.

fix

Set node.type to one of: 'region', 'point', 'line', 'polygon'.
