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 index.ts:641

Instantiates a new Mesh instance.

Parameters:

Name

Type

Description

config

Config

Configuration options for Mesh

Returns: Mesh

An instance of Mesh

Methods

addOrdersAsync

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

Defined in index.ts:791

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 index.ts:720

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(page: number, perPage: number, snapshotID?: undefined | string): Promise‹GetOrdersResponse›

Defined in index.ts:762

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

Parameters:

Name

Type

Description

page

number

Page index at which to retrieve orders

perPage

number

Number of signedOrders to fetch per paginated request

snapshotID?

undefined | string

The DB snapshot at which to fetch orders. If omitted, a new snapshot is created

Returns: Promise‹GetOrdersResponse›

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

getStatsAsync

▸ getStatsAsync(): Promise‹Stats›

Defined in index.ts:703

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 index.ts:661

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 index.ts:676

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

OrderEvent[]

Returns: void

startAsync

▸ startAsync(): Promise‹void›

Defined in index.ts:687

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

Returns: Promise‹void›
