relay-sequelize-pagination
Relay Cursor-Based Pagination Support for Sequelize
This microlibrary exports a function that will mutate the limit
and criteria
fields of a Sequelize FindOptions
object with values based on Relay's pagination fields (e.g. first
, after
, last
, and before
).
const {addCursorPagingCriteria} = require("relay-sequelize-pagination").default;
resolve: (root, args) => {
const criteria = makeCriteriaForMyDomain(args); // An 'order' property should be added to the criteria here or in your repository.
addCursorPagingCriteria(criteria, args);
return connectionFromPromisedArraySlice(
myRepository.findAll(criteria),
args,
{
sliceStart: criteria.offset,
arrayLength: Number.MAX_VALUE // or the result of a count query
}
);
}
