Summary

This release adds numerous quality-of-life API improvements. Though there are technically breaking changes, you are unlikely to encounter them.

🎁 Features

• tx.get() and tx.scan() now accept an optional type parameter:

  // before:
  (await tx.get("foo")) as Todo|undefined
  (await tx.scan().toArray()) as Todo[]
  
  // now:
  await tx.get<Todo>("foo");
  await tx.scan<Todo>.toArray();
  

• push() and pull() now support an optional now: true argument:

  r.push({now: true});
  r.pull({now: true});
  

  This bypasses all debouncing and runs the push/pull immediately.

• push() and pull() now return a Promise. The promise resolves if the next push/pull succeeds, and rejects otherwise.

  try {
  	await r.push();
  	console.log("yay, push succeeded!");
  } catch {
  	console.error("boo, push failed");
  }
  

• Replicache.subscribe now supports an isEqual option to implement custom comparison of results. The default implementation is deepEqual, which is what it has always been.

  r.subscribe(
  	tx => new Map(...await getMapData(tx)), {
  		isEqual: (a, b) => a === b,
  	}
  );
  

• Replicache.subscribe now allows passing a bare callback function directly to the second parameter, rather than wrapping in an options object:

  // before:
  r.subscribe(tx => tx.get("foo"), { onData: val => console.log(val) });
  
  // now:
  r.subscribe(tx => tx.get("foo"), val => console.log(val));
  

• tx.put() has been renamed to tx.set() for consistency with ES6 Map. tx.put() remains but is deprecated.

  // before:
  tx.put("foo", "bar");
  
  // now:
  tx.set("foo", "bar");
  

• Replicache.clientID is now synchronous, not asynchronous.

  // before:
  console.log(await r.clientID);
  
  // now:
  console.log(r.clientID);
  

  Note that await r.clientID will still work since it’s fine to await anything in JavaScript. It just doesn’t do anything.

• tx.environment renamed to tx.location to avoid confusion with environment variables.

  // before:
  launchMissles: tx => {
    if (tx.environment === 'server') {
      // check auth
  	}
  	...
  }
  
  // now:
  if (tx.location === 'server')
  

  The old field name remains but is deprecated.
