Nest.js Paginate

Pagination and filtering helper method for TypeORM repositories or query builders using Nest.js framework.

• Pagination conforms to JSON:API
• Sort by multiple columns
• Search across columns
• Select columns
• Filter using operators ($eq, $not, $null, $in, $gt, $gte, $lt, $lte, $btw, $ilike, $sw, $contains)
• Include relations and nested relations
• Virtual column support
• Cursor-based pagination

Installation

npm install nestjs-paginate

| ⚠️ TypeORM appears unmaintained. | |------------------------------------------------------------| | Please npm i typeorm@npm:@helveg/typeorm@^0.3.21 instead. |

The fork contains several fixes used in this package. In some rare edge cases this package might not work without it.

Usage

Global configurations

You can configure the global settings for all paginated routes by updating the default global configuration using below method. Ideally, you need to do it as soon as possible in your application main bootstrap method, as it affects all paginated routes, and swagger generation logic.

import { updateGlobalConfig } from 'nestjs-paginate'

updateGlobalConfig({
  // this is default configuration
  defaultOrigin: undefined,
  defaultLimit: 20,
  defaultMaxLimit: 100,
});

Example

The following code exposes a route that can be utilized like so:

Endpoint

http://localhost:3000/cats?limit=5&page=2&sortBy=color:DESC&search=i&filter.age=$gte:3&select=id,name,color,age&withDeleted=true

Result

{
  "data": [
    {
      "id": 4,
      "name": "George",
      "color": "white",
      "age": 3
    },
    {
      "id": 5,
      "name": "Leche",
      "color": "white",
      "age": 6
    },
    {
      "id": 2,
      "name": "Garfield",
      "color": "ginger",
      "age": 4
    },
    {
      "id": 1,
      "name": "Milo",
      "color": "brown",
      "age": 5
    },
    {
      "id": 3,
      "name": "Kitty",
      "color": "black",
      "age": 3
    }
  ],
  "meta": {
    "itemsPerPage": 5,
    "totalItems": 12,
    "currentPage": 2,
    "totalPages": 3,
    "sortBy": [["color", "DESC"]],
    "search": "i",
    "filter": {
      "age": "$gte:3"
    }
  },
  "links": {
    "first": "http://localhost:3000/cats?limit=5&page=1&sortBy=color:DESC&search=i&filter.age=$gte:3",
    "previous": "http://localhost:3000/cats?limit=5&page=1&sortBy=color:DESC&search=i&filter.age=$gte:3",
    "current": "http://localhost:3000/cats?limit=5&page=2&sortBy=color:DESC&search=i&filter.age=$gte:3",
    "next": "http://localhost:3000/cats?limit=5&page=3&sortBy=color:DESC&search=i&filter.age=$gte:3",
    "last": "http://localhost:3000/cats?limit=5&page=3&sortBy=color:DESC&search=i&filter.age=$gte:3"
  }
}

Example (Cursor-based Pagination)

The following code exposes a route using cursor-based pagination:

Endpoint

http://localhost:3000/cats?limit=5&sortBy=lastVetVisit:ASC&cursor=V998328469600000

Result

{
  "data": [
    {
      "id": 3,
      "name": "Shadow",
      "lastVetVisit": "2022-12-21T10:00:00.000Z"
    },
    {
      "id": 4,
      "name": "Luna",
      "lastVetVisit": "2022-12-22T10:00:00.000Z"
    },
    {
      "id": 5,
      "name": "Pepper",
      "lastVetVisit": "2022-12-23T10:00:00.000Z"
    },
    {
      "id": 6,
      "name": "Simba",
      "lastVetVisit": "2022-12-24T10:00:00.000Z"
    },
    {
      "id": 7,
      "name": "Tiger",
      "lastVetVisit": "2022-12-25T10:00:00.000Z"
    }
  ],
  "meta": {
    "itemsPerPage": 5,
    "cursor": "V998328469600000"
  },
  "links": {
    "previous": "http://localhost:3000/cats?limit=5&sortBy=lastVetVisit:DESC&cursor=V001671616800000",
    "current": "http://localhost:3000/cats?limit=5&sortBy=lastVetVisit:ASC&cursor=V998328469600000",
    "next": "http://localhost:3000/cats?limit=5&sortBy=lastVetVisit:ASC&cursor=V998328037600000"
  }

   * }
   * ```
   */
  buildCountQuery: (qb: SelectQueryBuilder<T>) => SelectQueryBuilder<any>,
}

Usage with Query Builder

You can paginate custom queries by passing on the query builder:

Example

const queryBuilder = repo
  .createQueryBuilder('cats')
  .leftJoinAndSelect('cats.owner', 'owner')
  .where('cats.owner = :ownerId', { ownerId })

const result = await paginate<CatEntity>(query, queryBuilder, config)

Usage with Relations

Similar as with repositories, you can utilize relations as a simplified left-join form:

Example

Endpoint

http://localhost:3000/cats?filter.toys.name=$in:Mouse,String

Code

const config: PaginateConfig<CatEntity> = {
  relations: ['toys'],
  sortableColumns: ['id', 'name', 'toys.name'],
  filterableColumns: {
    'toys.name': [FilterOperator.IN],
  },
}

const result = await paginate<CatEntity>(query, catRepo, config)

Note: Embedded columns on relations have to be wrapped with brackets:

const config: PaginateConfig<CatEntity> = {
  sortableColumns: ['id', 'name', 'toys.(size.height)', 'toys.(size.width)'],
  searchableColumns: ['name'],
  relations: ['toys'],
}

Usage with Nested Relations

Similar as with relations, you can specify nested relations for sorting, filtering and searching:

Example

Endpoint

http://localhost:3000/cats?filter.home.pillows.color=pink

Code

const config: PaginateConfig<CatEntity> = {
  relations: { home: { pillows: true } },
  sortableColumns: ['id', 'name', 'home.pillows.color'],
  searchableColumns: ['name', 'home.pillows.color'],
  filterableColumns: {
    'home.pillows.color': [FilterOperator.EQ],
  },
}

const result = await paginate<CatEntity>(query, catRepo, config)

Usage with to-many relationships

You can filter parents by conditions on their to-many relations (one-to-many or many-to-many) using quantifiers. Quantifiers define how many related rows must satisfy the condition:

• $any (default): at least one related row matches the condition
• $all: all related rows match the condition
• $none: no related rows match the condition

Examples

Assume CatEntity has a one‑to‑many relation toys: CatToyEntity[] where CatToyEntity has a string column name.

• At least one toy named exactly "Ball":

  GET /cats?filter.toys.name=$any:$eq:Ball

• At least one toy whose name contains "red" (case-insensitive):

  GET /cats?filter.toys.name=$any:$ilike:red

• All toys must have names that start with "Chew":

  GET /cats?filter.toys.name=$all:$sw:Chew

• No toys named "Squeaky", including cats without any toys:

  GET /cats?filter.toys.name=$none:$eq:Squeaky

• One or more toys not named "Squeaky":

  GET /cats?filter.toys.name=$any:$not:$eq:Squeaky

Usage with Eager Loading

Eager loading should work with TypeORM's eager property out of the box:

Example

Code

@Entity()
export class CatEntity {
  // ...

  @OneToMany(() => CatToyEntity, (catToy) => catToy.cat, {
    eager: true,
  })
  toys: CatToyEntity[]
}

const config: PaginateConfig<CatEntity> = {
  loadEagerRelations: true,
  sortableColumns: ['id', 'name', 'toys.name'],
  filterableColumns: {
    'toys.name': [FilterOperator.IN],
  },
}

const result = await paginate<CatEntity>(query, catRepo, config)

Filters

Filter operators must be whitelisted per column in PaginateConfig.

Examples

Code

const config: PaginateConfig<CatEntity> = {
  // ...
  filterableColumns: {
    // Enable individual operators on a column
    id: [FilterOperator.EQ, FilterSuffix.NOT],

    // Enable all operators on a column
    age: true,
  },
}

?filter.name=$eq:Milo is equivalent with ?filter.name=Milo

?filter.age=$btw:4,6 where column age is between 4 and 6

?filter.id=$not:$in:2,5,7 where column id is not 2, 5 or 7

?filter.summary=$not:$ilike:term where column summary does not contain term

?filter.summary=$sw:term where column summary starts with term

?filter.seenAt=$null where column seenAt is NULL

?filter.seenAt=$not:$null where column seenAt is not NULL

?filter.createdAt=$btw:2022-02-02,2022-02-10 where column createdAt is between the dates 2022-02-02 and 2022-02-10

?filter.createdAt=$lt:2022-12-20T10:00:00.000Z where column createdAt is before iso date 2022-12-20T10:00:00.000Z

?filter.roles=$contains:moderator where column roles is an array and contains the value moderator

?filter.roles=$contains:moderator,admin where column roles is an array and contains the values moderator and admin

Jsonb Filters

You can filter on jsonb columns by using the dot notation. Json columns is limited to $eq operators only.

?filter.metadata.enabled=$eq:true where column metadata is jsonb and contains an object with the key enabled.

Multi Filters

Multi filters are filters that can be applied to a single column with a comparator.

Examples

?filter.createdAt=$gt:2022-02-02&filter.createdAt=$lt:2022-02-10 where column createdAt is after 2022-02-02 and before 2022-02-10

?filter.roles=$contains:moderator&filter.roles=$or:$contains:admin where column roles is an array and contains moderator or admin

?filter.id=$gt:3&filter.id=$and:$lt:5&filter.id=$or:$eq:7 where column id is greater than 3 and less than 5 or equal to 7

Note: The $and comparators are not required. The above example is equivalent to:

?filter.id=$gt:3&filter.id=$lt:5&filter.id=$or:$eq:7

Note: The first comparator on the the first filter is ignored because the filters are grouped by the column name and chained with an $and to other filters.

...&filter.id=5&filter.id=$or:7&filter.name=Milo&...

is resolved to:

WHERE ... AND (id = 5 OR id = 7) AND name = 'Milo' AND ...

Cursor-based Pagination

• paginationType: PaginationType.CURSOR
• Cursor format:
  • Numbers: [prefix1][integer:11 digits][prefix2][decimal:4 digits] (e.g., Y00000000001V2500 for -1.25 in ASC).
  • Dates: [prefix][value:15 digits] (e.g., V001671444000000 for a timestamp in DESC).
• Prefixes:
  • null: A (lowest priority, last in results).
  • ASC:
    • positive-int: V (greater than or equal to 1), X (less than 1)
    • positive-decimal: V (not zero), X (zero)
    • zero-int: X
    • zero-decimal: X
    • negative-int: Y
    • negative-decimal: V
  • DESC:
    • positive-int: V
    • positive-decimal: V
    • zero-int: N
    • zero-decimal: X
    • negative-int: M (less than or equal to -1), N (greater than -1)
    • negative-decimal: V (not zero), X (zero)
• Logic:
  • Numbers: Split into integer (11 digits) and decimal (4 digits) parts, with separate prefixes. Supports negative values, with sorting adjusted per direction.
  • Dates: Single prefix with 15-digit timestamp padded with zeros.
  • ASC: Negative → Zero → Positive → Null.
  • DESC: Positive → Zero → Negative → Null.
• Notes:
  • Multiple columns: sortBy can include multiple columns to create and sort by the cursor (e.g., sortBy=age:ASC&sortBy=createdAt:DESC), but at least one column must be unique to ensure consistent ordering.
  • Supported columns: Cursor sorting is available for numeric and date-related columns (string columns are not supported).
  • Decimal support: Numeric columns can include decimals, limited to 11 digits for the integer part and 4 digits for the decimal part.

Swagger

You can use two default decorators @ApiOkResponsePaginated and @ApiPagination to generate swagger documentation for your endpoints

@ApiOkPaginatedResponse is for response body, return http status is 200

@ApiPaginationQuery is for query params

  @Get()
  @ApiOkPaginatedResponse(
    UserDto,
    USER_PAGINATION_CONFIG,
  )
  @ApiPaginationQuery(USER_PAGINATION_CONFIG)
  async findAll(
    @Paginate()
    query: PaginateQuery,
  ): Promise<Paginated<UserEntity>> {

  }

There is also some syntax sugar for this, and you can use only one decorator @PaginatedSwaggerDocs for both response body and query params

  @Get()
  @PaginatedSwaggerDocs(UserDto, USER_PAGINATION_CONFIG)
  async findAll(
    @Paginate()
    query: PaginateQuery,
  ): Promise<Paginated<UserEntity>> {

  }

It is also possible to customize a swagger UI completely or partially, by following the default implementation and creating your own version of PaginatedSwaggerDocs decorator

Let's say you want some custom appearance for SortBy, you need to create a decorator for it

export function CustomSortBy(paginationConfig: PaginateConfig<any>) {
  return ApiQuery({
    name: 'sortBy',
    isArray: true,
    description: `My custom sort by description`,
    required: false,
    type: 'string',
  })
}

Now you can create your version of the whole docs decorator and use it

const CustomApiPaginationQuery = (paginationConfig: PaginateConfig<any>) => {
  return applyDecorators(
    ...[
      Page(),
      Limit(paginationConfig),
      Where(paginationConfig),
      CustomSortBy(paginationConfig),
      Search(paginationConfig),
      SearchBy(paginationConfig),
      Select(paginationConfig),
    ].filter((v): v is MethodDecorator => v !== undefined)
  )
}

function CustomPaginatedSwaggerDocs<DTO extends Type<unknown>>(dto: DTO, paginatedConfig: PaginateConfig<any>) {
  return applyDecorators(ApiOkPaginatedResponse(dto, paginatedConfig), CustomApiPaginationQuery(paginatedConfig))
}

You can use CustomPaginatedSwaggerDocs instead of default PaginatedSwaggerDocs

Troubleshooting

The package does not report error reasons in the response bodies. They are instead reported as debug level logging.

Common errors include missing sortableColumns or filterableColumns (the latter only affects filtering).
