Usage

findTsConfig

Retrieves the TsConfig by searching for the "tsconfig.json" file from a given current working directory.

import { findTsConfig } from "@visulima/tsconfig";

const tsconfig = await findTsConfig(); // => { path: "/Users/../Projects/visulima/packages/tsconfig/tsconfig.json", config: { compilerOptions: { ... } } }

writeTsConfig

Writes the provided TypeScript configuration object to a tsconfig.json file.

import { writeTsConfig } from '@visulima/package';

writeTsConfig({ compilerOptions: { ... } }/* ,{ cwd: "./" }*/);

readTsConfig

Reads the TypeScript configuration from a tsconfig.json file.

import { readTsConfig } from "@visulima/package";

const tsconfig = await readTsConfig("/Users/../Projects/visulima/packages/tsconfig.json" /* { tscCompatible: false } */);

tscCompatible: If true, the configuration will be parsed in a way that is compatible with the TypeScript compiler.
