Class: Mesh

The main class for this package. Has methods for receiving order events and sending orders through the 0x Mesh network.

Hierarchy

  • Mesh

Constructors

constructer

+ new Mesh(config: Config): Mesh

Defined in mesh.ts:132

Instantiates a new Mesh instance.

Parameters:

Name

Type

Description

config

Configuration options for Mesh

Returns: Mesh

An instance of Mesh

Properties

Optional wrapper

wrapper? : MeshWrapper

Defined in mesh.ts:129

Methods

addOrdersAsync

addOrdersAsync(orders: SignedOrder[], pinned: boolean): Promise‹ValidationResults

Defined in mesh.ts:269

Validates and adds the given orders to Mesh. If an order is successfully added, Mesh will share it with any peers in the network and start watching it for changes (e.g. filled, canceled, expired). The returned promise will only be rejected if there was an error validating or adding the order; it will not be rejected for any invalid orders (check results.rejected instead).

Parameters:

Name

Type

Default

Description

orders

SignedOrder[]

-

An array of orders to add.

pinned

boolean

true

Whether or not the orders should be pinned. Pinned orders will not be affected by any DDoS prevention or incentive mechanisms and will always stay in storage until they are no longer fillable.

Returns: Promise‹ValidationResults

Validation results for the given orders, indicating which orders were accepted and which were rejected.

getOrdersAsync

getOrdersAsync(perPage: number): Promise‹GetOrdersResponse

Defined in mesh.ts:207

Get all 0x signed orders currently stored in the Mesh node

Parameters:

Name

Type

Default

Description

perPage

number

200

number of signedOrders to fetch per paginated request

Returns: Promise‹GetOrdersResponse

the snapshotID, snapshotTimestamp and all orders, their hashes and fillableTakerAssetAmounts

getOrdersForPageAsync

getOrdersForPageAsync(perPage: number, minOrderHash?: undefined | string): Promise‹GetOrdersResponse

Defined in mesh.ts:240

Get page of 0x signed orders stored on the Mesh node at the specified snapshot

Parameters:

Name

Type

Description

perPage

number

Number of signedOrders to fetch per paginated request

minOrderHash?

undefined | string

The minimum order hash for the returned orders. Should be set based on the last hash from the previous response.

Returns: Promise‹GetOrdersResponse

Up to perPage orders with hash greater than minOrderHash, including order hashes and fillableTakerAssetAmounts

getStatsAsync

getStatsAsync(): Promise‹Stats

Defined in mesh.ts:190

Returns various stats about Mesh, including the total number of orders and the number of peers Mesh is connected to.

Returns: Promise‹Stats

onError

onError(handler: function): void

Defined in mesh.ts:152

Registers a handler which will be called in the event of a critical error. Note that the handler will not be called for non-critical errors. In order to ensure no errors are missed, this should be called before startAsync.

Parameters:

handler: function

The handler to be called.

▸ (err: Error): void

Parameters:

Name

Type

err

Error

Returns: void

onOrderEvents

onOrderEvents(handler: function): void

Defined in mesh.ts:165

Registers a handler which will be called for any incoming order events. Order events are fired whenver an order is added, canceled, expired, or filled. In order to ensure no events are missed, this should be called before startAsync.

Parameters:

handler: function

The handler to be called.

▸ (events: OrderEvent[]): void

Parameters:

Name

Type

events

Returns: void

startAsync

startAsync(): Promise‹void›

Defined in mesh.ts:174

Starts the Mesh node in the background. Mesh will automatically find peers in the network and begin receiving orders from them.

Returns: Promise‹void›
