The main class for this package. Has methods for receiving order events and sending orders through the 0x Mesh network.
Mesh
+ new Mesh(config: Config): Mesh
Defined in mesh.ts:132
Instantiates a new Mesh instance.
Parameters:
Returns: Mesh
An instance of Mesh
Optional wrapper• wrapper? : MeshWrapper
Defined in mesh.ts:129
▸ 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(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(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(): 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(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(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(): 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›
