7. Enable stricter type checking options like "reportOptionalSubscript", "reportOptionalMemberAccess", "reportOptionalCall", and "reportUntypedFunctionDecorator".
8. On a file-by-file basis, enable all type checking options by adding the comment `# pyright: strict` somewhere in the file.
### Running Pyright as part of Continuous Integration (CI)
Here is a simple bash script that installs the latest version of Pyright and runs it on a code base. It can be used in a CI environment.
```
#!/bin/bash
PATH_TO_PYRIGHT=`which pyright`
vercomp () {
if [[ $1 == $2 ]]
then
return 0
fi
local IFS=.
local i ver1=($1) ver2=($2)
# fill empty fields in ver1 with zeros
for ((i=${#ver1[@]}; i<${#ver2[@]}; i++))
do
ver1[i]=0
done
for ((i=0; i<${#ver1[@]}; i++))
do
if [[ -z ${ver2[i]} ]]
then
# fill empty fields in ver2 with zeros
ver2[i]=0
fi
if ((10#${ver1[i]} > 10#${ver2[i]}))
then
return 1
fi
if ((10#${ver1[i]} < 10#${ver2[i]}))
then
return 2
fi
done
return 0
}
# Node version check
echo "Checking node version..."
NODE_VERSION=`node -v | cut -d'v' -f2`
MIN_NODE_VERSION="10.15.2"
vercomp $MIN_NODE_VERSION $NODE_VERSION
# 1 == gt
if [[ $? -eq 1 ]]; then
echo "Node version ${NODE_VERSION} too old, min expected is ${MIN_NODE_VERSION}, run:"
echo " npm -g upgrade node"
exit -1

# Do we need to sudo?
echo "Checking node_modules dir..."
NODE_MODULES=`npm -g root`

# If we can't find pyright, install it.
echo "Checking pyright exists..."
if [ -z "$PATH_TO_PYRIGHT" ]; then
echo "...installing pyright"
${SUDO} npm install -g pyright
else
# already installed, upgrade to make sure it's current
# this avoids a sudo on launch if we're already current
echo "Checking pyright version..."
CURRENT=`pyright --version | cut -d' ' -f2`
REMOTE=`npm info pyright version`
if [ "$CURRENT" != "$REMOTE" ]; then
echo "...new version of pyright found, upgrading."
${SUDO} npm upgrade -g pyright
