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:

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:

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:

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:

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:

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:

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›
