[@vriad](https://twitter.com/vriad). The motivation for this library and a detailed comparison to various alternatives can be found at https://vriad.com/blog/zod.\n\nIf you find this package useful, leave a star to help more folks find it ⭐️🤏 -->\n\n<!-- <br/> -->\n\n> ⚠️ You might be encountering issues building your project if you're using zod@<1.10.2. This is the result of a bug in the TypeScript compiler. To solve this without updating, set `\"skipLibCheck\": true` in your tsconfig.json \"compilerOptions\". This issue is resolved in zod@1.10.2 and later.\n\n# What is Zod\n\nZod is a TypeScript-first schema declaration and validation library. I'm using the term \"schema\" to broadly refer to any data type/structure, from a simple `string` to a complex nested object.\n\nZod is designed to be as developer-friendly as possible. My goal is to eliminate duplicative type declarations wherever possible. With Zod, you declare a validator _once_ and Zod will automatically infer the static TypeScript type. It's easy to compose simpler types into complex data structures.\n\nSome other great aspects:\n\n- Zero de\n\nFile: CONTRIBUTING.md\nWhen it comes to open source, there are different ways you can contribute, all\nof which are valuable. Here's few guidelines that should help you as you prepare\nyour contribution.\n\n## Initial steps\n\nBefore you start working on a contribution, create an issue describing what you want to build. It's possible someone else is already working on something similar, or perhaps there is a reason that feature isn't implemented. The maintainers will point you in the right direction.\n\n<!-- ## Submitting a Pull Request\n\n- Fork the repo\n- Clone your forked repository: `git clone git@github.com:{your_username}/zod.git`\n- Enter the zod directory: `cd zod`\n- Create a new branch off the `master` branch: `git checkout -b your-feature-name`\n- Implement your contributions (see the Development section for more information)\n- Push your branch to the repo: `git push origin your-feature-name`\n- Go to https://github.com/vriad/zod/compare and select the branch you just pushed in the \"compare:\" dropdown\n- Submit the PR. The maintainers will follow up ASAP. -->\n\n## Development\n\nThe following steps will get you setup to contribute changes to this repo:\n\n1. Fork this repo.\n\n2. Clone your forked repo: `git clone git@github.com:{your_username}/zod.git`\n\n3. Run `yarn` to install dependencies.\n\n4. Start playing with the code! You can do some simple experimentation in `src/playground.ts` (see `yarn play` below) or start implementing a feature right away.\n\n### Commands\n\n**`yarn build`**\n\n- deletes `lib` and re-compiles `src` to `lib`\n\n**`yarn test`**\n\n- runs all Jest tests and generates coverage badge\n\n**`yarn testone`**\n\n- runs a single test file\n- example: `yarn testone src/__tests__/testFileNameHere.ts`\n\n**`yarn play`**\n\n- executes `src/playground.ts`, watches for changes. useful for experimentation\n\n### Tests\n\nZod uses Jest for testing. After implementing your contribution, write tests for it. Just create a new file under `src/__tests__` or add additional tests to the appropriate existing file.\n\nBe\n\nFile: LICENSE\nMIT License\n\nCopyright (c) 2020 Colin McDonnell\n\nPermission is hereby granted, free of charge, to any person obtaining a copy\nof this software and associated documentation files (the \"Software\"), to deal\nin the Software without restriction, including without limitation the rights\nto use, copy, modify, merge, publish, distribute, sublicense, and/or sell\ncopies of the Software, and to permit persons to whom the Software is\nfurnished to do so, subject to the following conditions:\n\nThe above copyright notice and this permission notice shall be included in all\ncopies or substantial portions of the Software.\n\nTHE SOFTWARE IS PROVIDED \"AS IS\", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR\nIMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY,\nFITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

This is the result of a bug in the TypeScript compiler. To solve this without updating, set `\"skipLibCheck\": true` in your tsconfig.json \"compilerOptions\". This issue is resolved in zod@1.10.2 and later.\n\n# What is Zod\n\nZod is a TypeScript-first schema declaration and validation library. I'm using the term \"schema\" to broadly refer to any data type/structure, from a simple `string` to a complex nested object.\n\nZod is designed to be as developer-friendly as possible. My goal is to eliminate duplicative type declarations wherever possible. With Zod, you declare a validator _once_ and Zod will automatically infer the static TypeScript type. It's easy to compose simpler types into complex data structures.\n\nSome other great aspects:\n\n- Zero de\n\nFile: CONTRIBUTING.md\nWhen it comes to open source, there are different ways you can contribute, all\nof which are valuable. Here's few guidelines that should help you as you prepare\nyour contribution.\n\n## Initial steps\n\nBefore you start working on a contribution, create an issue describing what you want to build. It's possible someone else is already working on something similar, or perhaps there is a reason that feature isn't implemented. The maintainers will point you in the right direction.\n\n<!-- ## Submitting a Pull Request\n\n- Fork the repo\n- Clone your forked repository: `git clone git@github.com:{your_username}/zod.git`\n- Enter the zod directory: `cd zod`\n- Create a new branch off the `master` branch: `git checkout -b your-feature-name`\n- Implement your contributions (see the Development section for more information)\n- Push your branch to the repo: `git push origin your-feature-name`\n- Go to https://github.com/vriad/zod/compare and select the branch you just pushed in the \"compare:\" dropdown\n- Submit the PR. The maintainers will follow up ASAP. -->\n\n## Development\n\nThe following steps will get you setup to contribute changes to this repo:\n\n1. Fork this repo.\n\n2. Clone your forked repo: `git clone git@github.com:{your_username}/zod.git`\n\n3. Run `yarn` to install dependencies.\n\n4. Start playing with the code! You can do some simple experimentation in `src/playground.ts` (see `yarn play` below) or start implementing a feature right away.\n\n### Commands\n\n**`yarn build`**\n\n- deletes `lib` and re-compiles `src` to `lib`\n\n**`yarn test`**\n\n- runs all Jest tests and generates coverage badge\n\n**`yarn testone`**\n\n- runs a single test file\n- example: `yarn testone src/__tests__/testFileNameHere.ts`\n\n**`yarn play`**\n\n- executes `src/playground.ts`, watches for changes. useful for experimentation\n\n### Tests\n\nZod uses Jest for testing. After implementing your contribution, write tests for it. Just create a new file under `src/__tests__` or add additional tests to the appropriate existing file.\n\nBe\n\nFile: LICENSE\nMIT License\n\nCopyright (c) 2020 Colin McDonnell\n\nPermission is hereby granted, free of charge, to any person obtaining a copy\nof this software and associated documentation files (the \"Software\"), to deal\nin the Software without restriction, including without limitation the rights\nto use, copy, modify, merge, publish, distribute, sublicense, and/or sell\ncopies of the Software, and to permit persons to whom the Software is\nfurnished to do so, subject to the following conditions:\n\nThe above copyright notice and this permission notice shall be included in all\ncopies or substantial portions of the Software.\n\nTHE SOFTWARE IS PROVIDED \"AS IS\", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR\nIMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY,\nFITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
