Function: initFusion()

function initFusion<TContext>(): FusionInstance<TContext>;

Defined in: packages/core/src/core/initFusion.ts:346

Initialize a Fusion instance with a fixed context type.

Call once per project. All factory methods on the returned instance automatically inherit the context type — zero generic repetition.

Type Parameters

Type Parameter	Default type	Description
TContext	void	The application-level context type

Returns

FusionInstance<TContext>

A FusionInstance with context-typed factories

Example

// Single definition, typically in src/fusion.ts
export const f = initFusion<AppContext>();

// Build tools with the Fluent API
const listUsers = f.query('users.list')
    .describe('List all users')
    .withOptionalNumber('limit', 'Max results (default: 50)')
    .handle(async (input, ctx) => {
        return ctx.db.users.findMany({ take: input.limit ?? 50 });
    });
