Hacking and Contributing
|
|
------------------------
|
|
|
|
The JavaScript code is now generated from TypeScript, so make sure you modify the
|
|
TypeScript and compile it, rather than modifying the JavaScript directly. To start
|
|
auto-compiling the TypeScript code, you may use:
|
|
|
|
```
|
|
/home/ethers> npm run auto-build
|
|
```
|
|
|
|
A very important part of ethers is its exhaustive test cases, so before making any
|
|
bug fix, please add a test case that fails prior to the fix, and succeeds after the
|
|
fix. All regression tests must pass.
|
|
|
|
Pull requests are always welcome, but please keep a few points in mind:
|
|
|
|
- Compatibility-breaking changes will not be accepted; they may be considered for the next major version
|
|
- Security is important; adding dependencies require fairly convincing arguments
|
|
- The library aims to be lean, so keep an eye on the `dist/ethers.min.js` filesize before and after your changes
|
|
- Add test cases for both expected and unexpected input
|
|
- Any new features need to be supported by us (issues, documentation, testing), so anything that is overly complicated or specific may not be accepted
|
|
|
|
If in doubt, please start an issue, and we can have a nice public discussion. :)
