tisk

tisk is a simpler alternative to tsc, the standard TypeScript compiler CLI.

Synopsis

usage: tisk [-h] [-v] [-o OUTPUT] [-d] [-m] [-p PATH] [-W WARNING]
            [file [file ...]]

Examples

# Output to stdout
echo "console.log('Hello, world')" | tisk | node

# All warnings as errors
tisk -Werror -o lib src

# Specific warnings as errors
tisk -Werror=implicit-any -Wimplicit-this -o lib src

# Source maps
tisk -m -o lib src

# Declarations
tisk -d -o lib src

# Map external import paths based on output directory
# Input: src/main.ts: import * as vendor from '../vendor'
# Output: dist/lib/main.js: import * as vendor from '../../vendor'
tisk -p vendor -o dist/lib src
# or
# Input: src/main.ts: import * as vendor from '../vendor'
# Output: dist/lib/main.js: import * as vendor from '../../libs'
tisk -p vendor:libs -o dist/lib src

Differences from tsc

tisk follows references to imports but does not compile them. To illustrate this:

$ mkdir example && cd example
$ mkdir src && echo "export {}" > src/index.ts
$ echo "import * as m from './src';" > main.ts
$ tsc --outDir lib main.ts
$ ls lib
main.js	src
$ rm -r lib
$ tisk -o lib main.ts
$ ls lib
main.js

As you can see, tsc brings in the src directory, compiles it, and outputs the result to lib while tisk only compiles the input files provided.

Because tisk behaves this way, its output is completely predictable and you can, for example, run it in parallel, splitting the input set any way you want.

Automatic relative import path mapping

tisk will automatically fix relative import paths among the set of input files and directories. This can allow you to, for example, combine two directories:

$ tisk -o lib src1 src2

If a file in src2 imports from src1 like so:

import * as foo from '../src1/foo';

On output, it will be transformed to:

import * as foo from './foo';

To map import paths that aren't in the set of inputs (eg. they might be compiled in a separate invocation), use the -p option as shown in the examples above.
