This repository contains a codemod script for use with JSCodeshift that help add try catch statements to asyc await calls.
yarn global add jscodeshiftgit clone https://github.com/vivek12345/async-await-codemod.git- Run
yarn installin the async-await-codemod directory jscodeshift -t <codemod-script> <path>codemod-script- path to the transform file, see available scripts below;path- files or directory to transform;- use the
-doption for a dry-run and use-pto print the output for comparison; - use the
--extensionsoption if your files have different extensions than.js(for example,--extensions js,jsx); - see all available jscodeshift options.
Converts async await functions like below:-
async function completeApplicationFlow() {
// wait for get session status api to check the status
let response;
response = await getSessionStatusApi();
// wait for getting next set of questions api
response = await getNextQuestionsApi();
// finally submit application
response = await submitApplication();
}To the following with try catch statements:-
async function completeApplicationFlow() {
// wait for get session status api to check the status
let response;
try {
response = await getSessionStatusApi();
} catch(e) {
console.log(e);
}
// wait for getting next set of questions api
try {
response = await getNextQuestionsApi();
} catch(e) {
console.log(e);
}
// finally submit application
try {
response = await submitApplication();
} catch(e) {
console.log(e);
}
}jscodeshift -t transforms/async-await-with-try-catch.js <path>If you want to replace the default console.log(e) with your custom function call for example error.handleError(e),
you can pass that as an option --catchBlock
jscodeshift -t transforms/async-await-with-try-catch.js <path> --catchBlock="error.handleError(e)"This will transform your code to:-
async function completeApplicationFlow() {
// wait for get session status api to check the status
let response;
try {
response = await getSessionStatusApi();
} catch(e) {
error.handleError(e)
}
// wait for getting next set of questions api
try {
response = await getNextQuestionsApi();
} catch(e) {
error.handleError(e)
}
// finally submit application
try {
response = await submitApplication();
} catch(e) {
error.handleError(e)
}
}Options to recast's printer can be provided
through the printOptions command line argument
jscodeshift -t transform.js <path> --printOptions='{"quote":"double"}'Show your ❤️ and support by giving a ⭐. Any suggestions and pull request are welcome !
