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 index.ts:576
Instantiates a new Mesh instance.
Parameters:
Returns: Mesh
An instance of Mesh
▸ addOrdersAsync(orders: SignedOrder[], pinned: boolean): Promise‹ValidationResults›
Defined in index.ts:650
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.
▸ onError(handler: function): void
Defined in index.ts:596
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 index.ts:611
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 index.ts:622
Starts the Mesh node in the background. Mesh will automatically find peers in the network and begin receiving orders from them.
Returns: Promise‹void›
