Codama ➤ Renderers ➤ JavaScript

This package generates JavaScript clients from your Codama IDLs. The generated clients are compatible with @solana/kit.

Installation

pnpm install @codama/renderers-js

Usage

Add the following script to your Codama configuration file.

{
    "scripts": {
        "js": {
            "from": "@codama/renderers-js",
            "args": ["clients/js/src/generated"]
        }
    }
}

An object can be passed as a second argument to further configure the renderer. See the Options section below for more details.

Options

The renderVisitor accepts the following options.

Name	Type	Default	Description
deleteFolderBeforeRendering	boolean	true	Whether the base directory should be cleaned before generating new files.
formatCode	boolean	true	Whether we should use Prettier to format the generated code.
prettierOptions	PrettierOptions	{}	The options to use when formatting the code using Prettier.
asyncResolvers	string[]	[]	The exhaustive list of ResolverValueNode's names whose implementation is asynchronous in JavaScript.
customAccountData	string[]	[]	The names of all AccountNodes whose data should be manually written in JavaScript.
customInstructionData	string[]	[]	The names of all InstructionNodes whose data should be manually written in JavaScript.
linkOverrides	Record<'accounts' | 'definedTypes' | 'instructions' | 'pdas' | 'programs' | 'resolvers', Record<string, string>>	{}	A object that overrides the import path of link nodes. For instance, { definedTypes: { counter: 'hooked' } } uses the hooked folder to import any link node referring to the counter type.
dependencyMap	Record<string, string>	{}	A mapping between import aliases and their actual package name or path in JavaScript.
dependencyVersions	Record<string, string>	{}	A mapping between external package names — e.g. @solana/kit — and the version range we should use for them — e.g. ^5.0.0. The renderer offers default values for all external dependencies it relies on but this option may be used to override some of these values or add new ones.
internalNodes	string[]	[]	The names of all nodes that should be generated but not exported by the index.ts files.
nameTransformers	Partial<NameTransformers>	{}	An object that enables us to override the names of any generated type, constant or function.
nonScalarEnums	string[]	[]	The names of enum variants with no data that should be treated as a data union instead of a native enum type. This is only useful if you are referencing an enum value in your Codama IDL.
renderParentInstructions	boolean	false	When using nested instructions, whether the parent instructions should also be rendered. When set to false (default), only the instruction leaves are being rendered.
useGranularImports	boolean	false	Whether to import the @solana/kit library using sub-packages such as @solana/addresses or @solana/codecs-strings. When set to true, the main @solana/kit library is used which enables generated clients to install it as a peerDependency.
syncPackageJson	boolean	false	Whether to update the dependencies of the existing package.json — or create a new package.json when missing — at the provided packageFolder option if provided.
packageFolder	string		The package folder of the generated JS client — i.e. where the package.json lives. Note that this option must be provided for the syncPackageJson option to work.
