node-types
Types to be used with Substrate node
The types to provide polkadot-js, sidecar, etc when working with testnet or mainnet. The file v22.js contains types to be used till spec version 22. The file v23.js contains types to be used starting from spec version 23. Coincidentally, the types are same for testnet and mainnet.
Starting from spec version 27 (v27.js), PoS chain starts. Note that spec_name is different.
When using polkadot-js, the object exported from bundle.js should be passed to typesBundle argument of ApiPromise.create.
Add to your project as yarn add @docknetwork/node-types or npm install @docknetwork/node-types.
Sidecar
When using sidecar, build the package first with yarn build. This will create a dist folder in the same directory. Then run the following command to connect to mainnet
SAS_SUBSTRATE_TYPES_BUNDLE=<path to dist/index.cjs.js> SAS_SUBSTRATE_WS_URL=<websocket endpoint of the node> yarn dev
For mainnet, the endpoint is wss://mainnet-node.dock.io/. Also note that we have tested sidecar versions from 8.0.3 to 9.1.0 only.
