Azle 0.21.0 Documentation

[lastmjs]

• add new bitcoin examples
• Document all features
• Put in limitations: CORS is not respected
• add all new express examples to the examples section and hello_world readme
• update documentation about dfx, I believe the path stuff has now changed...I only had to restart my terminal, not sure what others might need to do. We can probably just...maybe say nothing because the installation has helpful output
• update dfx path stuff documentation
• explain that fd_readdir does not work
• add authentication documentation
• document that the Headers object cannot be used for authentication
• document that the following will not work: cache, keepalive and everything else that might not work
• document that the fetch is designed currently for the browser and not for nodejs
• explain that many of the default headers that the browser might attach will be missing
• explain that azle/client is really designed to be a web client
• Ethereum and all other supporting documentation (fetch, authentication)
• Document native compilation, explain installing rust, operating system dependencies, wasi2ic, and wasmedge_quickjs
• Do we have documentation explaining that if they override the init and/or postupgrade method they need to set the node server in their overrides? This is for hybrid canisters, essentially a Server that also has Canister methods
• HTTP outcalls/fetch from a canister have a number of limitations that we might should point out, see here for more information: Backend fetch http #1706 (comment)
