Query API
The Query API provides a programmatic API for running CRUD operations against your GraphQL API.
For each list in your system the following API is available at context.query.<listName>
.
{findOne({ where: { id }, query }),findMany({ where, take, skip, orderBy, query }),count({ where }),createOne({ data, query }),createMany({ data, query }),updateOne({ where: { id }, data, query }),updateMany({ data, query }),deleteOne({ where: { id }, query }),deleteMany({ where, query }),}
The arguments to these functions closely correspond to their equivalent GraphQL APIs, making it easy to switch between the programmatic API and the GraphQL API.
The query
argument, which defaults to 'id'
for all the functions, is a string which indicates which fields should be returned by the operation.
Unless otherwise specified, the other arguments to all functions are required.
The functions in the API all work by directly executing queries and mutations against your GraphQL API.
findOne
const user = await context.query.User.findOne({where: { id: '...' },query: 'id name posts { id title }',});
findMany
All arguments are optional.
const users = await context.query.User.findMany({where: { name: { startsWith: 'A' } },take: 10,skip: 20,orderBy: [{ name: 'asc' }],query: 'id name posts { id title }',});
count
All arguments are optional.
const count = await context.query.User.count({where: { name: { startsWith: 'A' } },});
createOne
const user = await context.query.User.createOne({data: {name: 'Alice',posts: { create: [{ title: 'My first post' }] },},query: 'id name posts { id title }',});
createMany
const users = await context.query.User.createMany({data: [{name: 'Alice',posts: [{ create: { title: 'Alices first post' } }],},{name: 'Bob',posts: [{ create: { title: 'Bobs first post' } }],},],query: 'id name posts { id title }',});
updateOne
const user = await context.query.User.updateOne({where: { id: '...' },data: {name: 'Alice',posts: { create: [{ title: 'My first post' }] },},query: 'id name posts { id title }',});
updateMany
const users = await context.query.User.updateMany({data: [{where: { id: '...' },data: {name: 'Alice',posts: [{ create: { title: 'Alices first post' } }],},},{where: { id: '...' },data: {name: 'Bob',posts: [{ create: { title: 'Bobs first post' } }],},},],query: 'id name posts { id title }',});
deleteOne
const user = await context.query.User.deleteOne({where: { id: '...' },query: 'id name posts { id title }',});
deleteMany
const users = await context.query.User.deleteMany({where: [{ id: '...' }, { id: '...' }],query: 'id name posts { id title }',});
