## install

## api
### createDataLoaderSession
create a session and add to context when you create new context(per request).
session function returns dataloader function from normal function.
#### code
```ts
const session = createDataLoaderSession()
// add it to context
const getData = (keys: string[]) => {
// find data keys: ['key1', 'key2', 'key3']
return [...data]
}
async function resolver(parent, args, context) {
context.session(getData).load('key1')
context.session(getData).load('key2')
context.session(getData).load('key3')
}
```
### dataLoaderSorter
`dataloader` does not support sorting, you need to sorter.
#### code
```ts
const resolver = (keys: string[]) => {
type Item = {
id: string
}
const sql = `
select *
from table
where id in (${keys})`
// query returns Promise
return query(sql).then(dataLoaderSorter(keys, 'id'))
}
```
