7 Cons of ethers.js

• 1. Learning curve: While ethers.js offers extensive functionality, it may have a slight learning curve for developers who are new to Ethereum development or TypeScript. However, the comprehensive documentation and community support can help mitigate this challenge.
• 2. Limited compatibility with other blockchains: As the name suggests, ethers.js primarily focuses on Ethereum and may not offer the same level of support for other blockchains. Developers looking to build applications on alternative blockchains may need to explore other libraries.
• 3. Limited tooling ecosystem: Compared to more established Ethereum development frameworks like Web3.js, ethers.js has a smaller tooling ecosystem. This means that developers may have fewer options when it comes to integrating additional tools and libraries.
• 4. Relatively new compared to Web3.js: While ethers.js is gaining popularity, it is still relatively newer compared to Web3.js, which has been widely used in the Ethereum ecosystem for a longer time. This may result in fewer online resources and community discussions specifically tailored to ethers.js.
• 5. Less adoption in existing projects: Since Web3.js has been the go-to library for Ethereum development for many years, existing projects may already be built using Web3.js. This could pose challenges for developers looking to integrate ethers.js into legacy codebases.
• 6. Lack of official support from Ethereum Foundation: Unlike Web3.js, which is officially supported by the Ethereum Foundation, ethers.js does not have the same level of official backing. However, it has gained significant traction and community support on its own.
• 7. Potential future changes: As with any technology, there is always the possibility of future changes that may affect compatibility or require updates to existing code. Developers using ethers.js should stay informed about updates and changes in order to ensure their applications remain compatible and secure.

Cases when ethers.js does not work

1. Unsupported Networks: ethers.js may not work with all blockchain networks. It is primarily designed to work with Ethereum and Ethereum-compatible networks. If you are trying to use ethers.js with a blockchain that is not Ethereum-based, you may encounter compatibility issues and it may not function as expected.
2. Outdated Versions: If you are using an outdated version of ethers.js, it may not work properly. Newer versions of ethers.js often come with bug fixes, performance improvements, and new features. It is important to keep your version of ethers.js up to date to ensure its functionality.
3. Unsupported Browsers: The compatibility of ethers.js can be affected by the browser environment in which it is being used. While ethers.js is designed to work with most modern browsers, there may be certain older or less common browsers that do not fully support all of its features. It is recommended to use the latest versions of popular browsers such as Google Chrome, Mozilla Firefox, or Safari for the best experience with ethers.js.
4. Incorrect Configuration: If you have misconfigured ethers.js or have not set it up correctly, it may not work as expected. This includes incorrect network settings, incorrect provider configurations, or missing dependencies. It is important to follow the documentation and guidelines provided by ethers.js to ensure proper configuration.
5. Network Connectivity Issues: The functionality of ethers.js relies on a stable and reliable internet connection. If you experience network connectivity issues, ethers.js may not be able to communicate with the blockchain network effectively. This can result in errors or unexpected behavior.
