Constructors
constructor
• new ConvexReactClient(address, options?)
Parameters
| Name | Type | Description |

Methods
setAuth
▸ setAuth(fetchToken, onChange?): void
Set the authentication token to be used for subsequent queries and mutations.
fetchToken will be called automatically again if a token expires.
fetchToken should return null if the token cannot be retrieved, for example
when the user's rights were permanently revoked.
Parameters
| Name | Type | Description |
|---|---|---|
fetchToken | AuthTokenFetcher | an async function returning the JWT-encoded OpenID Connect Identity Token |
onChange? | (isAuthenticated: boolean) => void | a callback that will be called when the authentication status changes |
Returns
void
Defined in
clearAuth
▸ clearAuth(): void
Clear the current authentication token if set.
Returns
void
Defined in
watchQuery
▸ watchQuery<Query>(query, ...argsAndOptions): Watch<FunctionReturnType<Query>>
Construct a new Watch on a Convex query function.
Most application code should not call this method directly. Instead use the useQuery hook.
Type parameters
| Name | Type |
|---|---|
Query | extends FunctionReference<"query"> |
Parameters
| Name | Type | Description |
|---|---|---|
query | Query | A FunctionReference for the public query to run. |
...argsAndOptions | ArgsAndOptions<Query, WatchQueryOptions> | - |
Returns
Watch<FunctionReturnType<Query>>
The Watch object.
Defined in
mutation
▸ mutation<Mutation>(mutation, ...argsAndOptions): Promise<FunctionReturnType<Mutation>>
Execute a mutation function.
Type parameters
| Name | Type |
|---|---|
Mutation | extends FunctionReference<"mutation"> |
Parameters
| Name | Type | Description |
|---|---|---|
mutation | Mutation | A FunctionReference for the public mutation to run. |
...argsAndOptions | ArgsAndOptions<Mutation, MutationOptions<FunctionArgs<Mutation>>> | - |
Returns
Promise<FunctionReturnType<Mutation>>
A promise of the mutation's result.
Defined in
action
▸ action<Action>(action, ...args): Promise<FunctionReturnType<Action>>
Execute an action function.
Type parameters
| Name | Type |
|---|---|
Action | extends FunctionReference<"action"> |
Parameters
| Name | Type | Description |
|---|---|---|
action | Action | A FunctionReference for the public action to run. |
...args | OptionalRestArgs<Action> | An arguments object for the action. If this is omitted, the arguments will be {}. |
Returns
Promise<FunctionReturnType<Action>>
A promise of the action's result.
Defined in
query
▸ query<Query>(query, ...args): Promise<FunctionReturnType<Query>>
Fetch a query result once.
Most application code should subscribe to queries instead, using the useQuery hook.
Type parameters
| Name | Type |
|---|---|
Query | extends FunctionReference<"query"> |
Parameters
| Name | Type | Description |
|---|---|---|
query | Query | A FunctionReference for the public query to run. |
...args | OptionalRestArgs<Query> | An arguments object for the query. If this is omitted, the arguments will be {}. |
Returns
Promise<FunctionReturnType<Query>>
A promise of the query's result.
Defined in
connectionState
▸ connectionState(): ConnectionState
Get the current ConnectionState between the client and the Convex backend.
Returns
ConnectionState
The ConnectionState with the Convex backend.
Defined in
close
▸ close(): Promise<void>
Close any network handles associated with this client and stop all subscriptions.
Call this method when you're done with a ConvexReactClient to dispose of its sockets and resources.
Returns
Promise<void>
A Promise fulfilled when the connection has been completely closed.
