import { ChainRegistryFetcher, ChainRegistryFetcherOptions } from '@chain-registry/utils';
const options: ChainRegistryFetcherOptions = {
urls: [
'https://raw.githubusercontent.com/cosmos/chain-registry/master/osmosis/chain.json',
'https://raw.githubusercontent.com/cosmos/chain-registry/master/osmosis/assetlist.json',

};
const registry = new ChainRegistry(options);
await registry.fetchUrls();
We currently only support fetching JSON schemas as defined in https://github.com/cosmos/chain-registry. Supported are assetlist.schema.json
, chain.schema.json
and ibc_data.schema.json
.
You can set the ChainRegistry.urls
property and call ChainRegistry.fetchUrls()
registry.urls = [
// urls to fetch
];
await registry.fetchUrls();
Or, you can simply call ChainRegistry.fetch()
await registry.fetch('https://some-json-schema.com/some-schema.json');
You can get generated asset lists directly from the registry:
// generated asset lists
const generated: AssetList[] = registry.getGeneratedAssetLists('osmosis');
You can get generated AssetList[]
objects directly from the ChainRegistry
via the assetLists
method:
// you can also get generated assets from ChainInfo object
const chainInfo: Chain = registry.getChainInfo('osmosis');
const generatedAssets: AssetList[] = chainInfo.assetLists;
You can get Chain
object directly from the ChainRegistry
via the getChain
method:
// get Chain from registry
const chain: Chain = registry.getChain('osmosis');
or get the ChainInfo
object:
const chainInfo: ChainInfo = registry.getChainInfo('osmosis');
// AssetList[] of the generated assets
const assetes: AssetList[] = chainInfo.assetLists;
// Chain
const chain: Chain = chainInfo.chain;
// AssetList[] of the native assets
const assetes: AssetList[] = chainInfo.nativeAssetLists;
