# @polkadot-api/metadata-builders
This package has multiple functions that read a metadata object, denormalizes it, and builds other structures needed for different processes
## getLookupFn
```ts
function getLookupFn(
lookupData: Metadata["lookup"],
): (id: number) => LookupEntry
```
Given the lookup property of a metadata, returns a function that will give the `LookupEntry` for an id.
The `LookupEntry` is a denormalized data structure for one entry in the metadata. It also "shortcuts" type references when those are pointers (composites or tuples of length 1). Essentially, it's a union of each of the different types that can be found in the lookup, mostly equivalent to something like:
```ts
type TerminalVar =
| PrimitiveVar // u8, str, char, i128, etc.
| CompactVar
| BitSequenceVar
| AccountId32
type ComposedVar =
| TupleVar
| StructVar
| SequenceVar
| ArrayVar
| OptionVar
| ResultVar
| EnumVar
type LookupEntry = TerminalVar | ComposedVar
```
Where, for instance, a StructVar is of the shape
```ts
type StructVar = {
type: "struct"
value: Record<string, LookupEntry>
}
```
It's useful to get types referenced by storage calls, etc.
## getDynamicBuilder
```ts
function getDynamicBuilder(lookupData: Metadata): {
buildDefinition: (id: number) => Codec
buildConstant: (pallet: string, name: string) => Codec
buildEvent: (pallet: string, name: string) => VariantEntry
buildError: (pallet: string, name: string) => VariantEntry
buildCall: (pallet: string, name: string) => VariantEntry
buildStorage: (pallet: string, entry: string) => StorageEntry
buildRuntimeCall: (api: string, method: string) => RuntimeEntry
}
```
Generates all the codecs needed to SCALE encode or decode the data for any interaction with the chain.
`buildDefinition` returns the codec for the type identified by the parameter `id`
`buildConstant` returns the codec for the requested constant (equivalent as calling `buildDefinition` with the type id of that constant)
`buildEvent`, `buildError` and `buildCall` return an object with the codec, and the indices of the pallet and entry within the metadata:
```ts
interface VariantEntry {
location: [number, number] // [palletIdx, entryIdx],
codec: Codec
}
```
`buildStorage` creates all the encoders/decoders needed to encode a storage call and decode its result:
```ts
interface StorageEntry {
// Encodes the arguments of the storage call.
enc: (...args: any[]) => string
// Decodes the result from the storage call.
dec: (value: string) => any
// Decodes the arguments of the storage call
keyDecoder: (value: string) => any[]
// Expected number of arguments
len: number
// Decoded fallback value as defined in the metadata entry
fallback: unknown
}
```
Similarly, `buildRuntimeCall` returns the codecs for both encoding the arguments of the runtime call, and the codec for decoding the result
```ts
interface RuntimeEntry {
args: Codec<any[]>
value: Codec<any>
}
```
## getChecksumBuilder
```ts
function getChecksumBuilder(metadata: Metadata): {
buildDefinition: (id: number) => string | null
buildRuntimeCall: (api: string, method: string) => string | null
buildStorage: (pallet: string, entry: string) => string | null
buildCall: (pallet: string, name: string) => string | null
buildEvent: (pallet: string, name: string) => string | null
buildError: (pallet: string, name: string) => string | null
buildConstant: (pallet: string, constantName: string) => string | null
}
```
Generates the checksums for the different components defined in the metadata.
`buildDefinition` builds the checksum of one of the types in the lookup. The rest of the methods build the checksum for each of the interfaces of the chain.
