It allows developers to introduce TypeScript incrementally by leveraging the parsing of TypeScript compiler output (tsc)\n\n## Usage\n\n```bash\nnpm install typestep --save-dev\n```\n\n\u003e [!WARNING]\n\u003e Do Not Use `--pretty` option with `tsc`\n```bash\ntsc --noEmit \u003e tsc-output.log\n```\n\n### Config file\n\n#### Init config file\n\nThe `typestep init` command creates your Typestep config file by analyzing the tsc output, for each file that has TypeScript errors, it will automatically generate a configuration that ignores the specific error codes found in that file. This allows for a granular approach to TypeScript migration, where you can selectively ignore certain types of errors while addressing others.\n\n```bash\ntypestep init tsc-output.log\n```\n\n#### Or create your config file\n\n```ts\n// typestep.config.ts\nimport type { TypestepConfig } from 'typestep'\n\nexport default {\n  ignoredFiles: {\n    'src/foo.ts': true, // ignore all errors\n    'src/bar.ts': {\n      ignoredTsErrorCodes: ['TS2339', 'TS2345'] // ignore only ts error codes\n    }\n  },\n  ignoredTsErrorCodes: [ // global ts error codes to ignore\n    'TS2322'\n  ],\n  fullOutputErrors: false, // get full output errors (default: false)\n} satisfies TypestepConfig\n```\n\n### Run typestep\n\nThe `typestep run` command analyzes the tsc output file and compares it with your Typestep configuration. It shows you:\n- TypeScript errors that need to be fixed in non-ignored files\n- Files and error codes that can be removed from the configuration as their corresponding errors no longer exist\n\n```bash\ntypestep run tsc-output.log\n```\n\n## License\nMIT\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjoris-gallot%2Ftypestep","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjoris-gallot%2Ftypestep","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjoris-gallot%2Ftypestep/lists"}
