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
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
â–¸ 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:
â–ª handler: function
The handler to be called.
â–¸ (err: Error): void
Parameters:
Name
Type
err
Error
Returns: void
onOrderEvents
â–¸ 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:
â–ª handler: function
The handler to be called.
â–¸ (events: OrderEvent[]): void
Parameters:
Name
Type
events
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›
