A TypeScript library suite for development on the Tezos blockchain

Taquito is a TypeScript library suite made available as a set of npm packages aiming to make building on top of Tezos easier and more enjoyable.

Get up and running using and contributing to the library quickly: Taquito is written in an idiomatic TypeScript style and includes a set of ready-made React components.

Usable in any JavaScript project on the front- or back-end with minimal dependencies, Taquito has no reliance on any stack by default (except the canonical Tezos RPC node).

Taquito comes complete with:

• a well-documented API using TypeDoc
• nightly and continuous integration tests against the Tezos node
• versioned releases published to npmjs.org

taquito is organized as a mono repository from which several npm packages are built and published. Packages are in the packages/ directory, each one with a README file.

We publish gpg signed packages to npmjs.org under the @taquito handle.

The TypeDoc style API documentation is available here

Version releases use "Semantic Versioning" style version numbers that deviate from SemVer norms when it comes to the "Major" number.

We use SemVer style versions for Taquito, but we make the "Major" version number track against the latest Tezos economical protocol we have tested on.

For example, in August 2019, the economic protocol was 004-Pt24m4xi, and 005-PsBABY5H was (is) working its way through the on-chain amendment process. Therefore the current version number for Taquito would be v4.0.0. During this time, we would start working on v5.0.0-beta.1 on the expectation (but not the assumption) that it shall become our new economic protocol.

When we are confident that the next protocol proposal will be promoted, AND we have implemented and tested interoperability with the new protocol (and potentially node RPC changes), we shall then release v5.0.0 BEFORE the chain transitions to the new protocol.

It is essential that the packages supporting the new protocol be released before the chain transitions to the new economic protocol so that developers who build on top of Taquito have time to update and test their projects.

During "Major" version updates, breaking changes in the Taquito public APIs MAY include breaking changes, for which we will make a strong effort to announce and document in our release notes. The Minor and Patch version numbers follow SemVer norms.

All releases are backward compatible with chain data back to the genesis block. Support for older Tezos node RPCs is maintained where feasible but will be dropped eventually. Tezos node RPC support also depends on what versioning strategy gets adopted by the Tezos node developed by Nomadic Labs. At the time of writing, this is unclear.

Supported versions of the Taquito packages will be maintained for the current and next protocol versions. Teams using older versions are encouraged to update, but they are encouraged to contact us if blockers exist.

Releases are "rolled" by the project maintainers outside of CI infrastructure and pushed to npmjs.org repositories and the Github releases page. The maintainers sign all official releases.

We hope to reduce the attack surface for software supply chain attacks by doing releases from outside of the CI processes. We reduce some attack surfaces for software supply chain attacks by making releases from outside of the CI infrastructure.

Releases will be (git tags and npm packages) will be signed either by keybase/jevonearth or keybase/simrob. Releases not signed or signed by other keys should not be expected.

See the top-level package.json file. Some common targets are:

• npm run test: Run tests
• npm run build: Generate bundles and typings, create docs
• npm run lint: Lints code
• npm run example: Run an example node js app that does a tour of all the functionality
• npm run commit: Commit using conventional commit style

• Install lerna globally npm install -g lerna
• Run npm install
• Run lerna bootstrap --force-local
• Run npm run build

• Run npm run lint
• Run npm run test
• To commit, please use npm run commit

The Tezos Taquito website is built using Docusaurus To run the Taquito website in development mode locally, run the following commands:

cd website
yarn
yarn start
