Codama ➤ Renderers ➤ JavaScript Umi

This package generates JavaScript clients from your Codama IDLs. The generated clients are compatible with Metaplex's Umi framework.

Installation

pnpm install @codama/renderers-js-umi

[!NOTE] This package is not included in the main codama package.

However, note that the renderers package re-exports the renderVisitor function of this package as renderJavaScriptUmiVisitor.

Usage

Once you have a Codama IDL, you can use the renderVisitor of this package to generate JavaScript clients compatible with Umi. You will need to provide the base directory where the generated files will be saved and an optional set of options to customize the output.

// node ./codama.mjs
import { renderVisitor } from '@codama/renderers-js-umi';

const pathToGeneratedFolder = path.join(__dirname, 'clients', 'js', 'src', 'generated');
const options = {}; // See below.
codama.accept(renderVisitor(pathToGeneratedFolder, options));

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.
throwLevel	'debug' \| 'trace' \| 'info' \| 'warn' \| 'error'	'error'	When validating the Codama IDL, the level at which the validation should throw an error.
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.
internalNodes	string[]	[]	The names of all nodes that should be generated but not exported by the index.ts files.
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.
