As niklasf points out here, dests is supposed to be a map instead of an object. Replace the calcMovable function with this code and it should work:
const calcMovable = () => {
const dests = new Map()
chess.SQUARES.forEach(s => {
const ms = chess.moves({ square: s, verbose: true })
if (ms.length) dests.set(s, ms.map(m => m.to))
})
return {
free: false,
dests,
color: "white"
}
}
from react-chessground.
const calcMovable = () => {
const dests = new Map()
chess.SQUARES.forEach(s => {
const ms = chess.moves({ square: s, verbose: true })
if (ms.length) dests.set(s, ms.map(m => m.to))
})
return {
free: false,
dests,
color: "white"
}
}
This work, thanks. I thought map shouldn't work, because movable props has object type.
Anyway, example demo code should be corrected.

I went ahead and created pull request #37.
from react-chessground.
The 1.5 build of react-chessground uses chessground ^7.6.12 which has some bugs where dests is expected to be a Map in some cases and a POJO in others. I was able to work around this issue with the following code. I've left my debugging code in.
const onAction = (action) => (data) => {
console.log(`${action}`, data)
}
const calcMovable = () => {
const dests = new Map()
chess.SQUARES.forEach(s => {
const ms = chess.moves({square: s, verbose: true})
if (ms.length) dests.set(s, ms.map(m => m.to))
})
const destsObj = {}
dests.forEach((v,k)=>destsObj[k]=v)
destsObj.get = (k) => destsObj[k]
console.log('destsObj', destsObj)
const config = {
free: false,
dests: destsObj,
color: "white",
events: {
after: onAction('cg.events(move).after'),
afterNewPiece: onAction('cg.events(move).afterNewPiece'),
}
}
console.log('calcMovable', config)
return config
}
