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:142

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 mesh.ts:292

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:221

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 mesh.ts:263

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 mesh.ts:204

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:162

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:177

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 mesh.ts:188

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

Returns: Promise‹void›
