typesync
Install missing TypeScript typings for dependencies in your package.json
.
Install
npm install -g typesync
You can also use it directly with npx
which will install it for you:
npx typesync
Usage
typesync [path/to/package.json] [--dry]
Path is relative to the current working directory. If omitted, defaults to package.json
.
Note: typesync
only modifies your package.json
- you still need to run npm install
, or — if drinking the k00laid — yarn
.
--dry[=fail]
If --dry
is specified, will not actually write to the file, it only prints added/removed typings.
The same is true for --dry=fail
, with the additional effect of failing the command in case there are changes.
This is useful for CI scenarios.
--ignoredeps
To ignore certain sections, you can use the --ignoredeps=
flag. For example, to ignore devDependencies
, use --ignoredeps=dev
. To ignore multiple, comma-separate them, like this: --ignoredeps=deps,peer
(ignores dependencies
and peerDependencies
).
--ignoredeps=deps
— ignoresdependencies
--ignoredeps=dev
— ignoresdevDependencies
--ignoredeps=peer
— ignorespeerDependencies
--ignoredeps=optional
— ignoresoptionalDependencies
--ignorepackages
To ignore certain packages, you can use the --ignorepackages=
flag. For example, to ignore nodemon
, use --ignorepackages=nodemon
.
To ignore multiple, comma-separate them, like this: --ignorepackages=nodemon,whatever
(ignores nodemon
and whatever
).
Using a config file
Alternatively, you can use a TypeSync config file: .typesyncrc
or a "typesync"
section in your package.json
. TypeSync will automatically search for configuration files. See cosmiconfig for details.
// .typesyncrc
{
"ignoreDeps": ["dev"],
"ignorePackages": ["nodemon"]
}
Run TypeSync Automatically After Every Install
To run TypeSync and install packages automatically after every package install, create a file called install-with-types.sh
with the following content:
npm install $1
npx typesync
npm install
If you use yarn
, use this instead:
yarn add $1
yarn typesync
yarn
Run this command to make the file executable:
chmod +x install-with-types.sh
Add the following to package.json
:
{
"scripts": {
"i": "./install-with-types.sh"
}
}
Then install packages like this:
npm run i <pkg name>
# Or, with yarn:
yarn i <pkg name>
Typings packages
TypeSync will add typings for packages that:
- have a
@types/package
available - don't already provide typings internally (the
typings
andtypes
field inpackage.json
)
TypeSync will try to respect semver parity for the code and typings packages, and will fall back to the latest available typings package.
When writing the typings package version to package.json
, the ~
semver range is used. This is because typings published via DefinitelyTyped align typings versions with library versions using major and minor only.
For example, if you depend on react@^16.14.0
, then TypeSync will only look for typings packages that match 16.14.*
.
Monorepos
TypeSync added support for monorepos in v0.4.0. It will look at packages
/workspaces
globs in package.json
and sync every matching file in one fell swoop.
Why?
Installing typings manually sucks. Flow has flow-typed
which installs type definitions by looking at a package.json
, which would be cool to have for TypeScript. Now we do!
